12V Lithium Pros batteries can be charged with any three stage battery charger (Constant Current/Constant Voltage) without a desulfation mode that is made for “Gel” batteries.The battery charger must exit absorption mode and go to float mode at 1.25A or higher. Battery chargers for “flooded/maintenance free/standard batteries” should not be used.Battery maintainers and any float mode on a three stage battery charger must be limited to 13.6V or less. At no time should the battery charger exceed the max amperage and voltage rating on the battery label.For maximum battery life, a true lithium ion battery charger is recommended.True lithium ion battery chargers have special algorithms to handle lithium ion batteries. They typically charge the battery differently when it is deeply discharged, rapid charge the battery when possible, and stop charging when the battery is full to prevent over-charge.Float charging should be avoided when possible. In general lithium ion batteries do not like to be held at 100% SoC.However, in applications where there is a constant parasitic load on the battery, float charging is allowed. It depends on your application but in general Lithium Prosbatteries operating within their accepted voltage range, at 70% DOD or less, and used at room temperature will last 10 years.The DOD, the storage temperature, and the ambient temperature during operation all work together to reduce the life of any lithium ion battery from its projected life span.For longest life do not charge the batteries when at the temperature extremes, either extreme cold or extreme heat. In marine, high temperatures are a concern.

Because of their occasional use, a Jump Starter with a Lithium-ion battery should be good because of its performance over an extended period. It is necessary to note that the best Lithium-ion jump starter should be able to perform well ever after a long period without being used. Durability and Reliability. The Freeman P800AJS 800 Amp Jump Starter and Power Supply is a compact and portable lithium-ion battery that can jump start 12V batteries in gasoline and diesel vehicles up to 10L including a compact car, sedan, SUV, full size pickup truck, boat, motorcycle, ATV, lawnmower, and more.

See our instructions for more details. Lithium Pros batteries are very safe. “Lithium ion battery” is the name for a type of battery with many variations, and each of those variations have their levels of risk.We use Lithium Iron Phosphate cells for their inherent safety. Further Lithium Pros has pioneered the concept of using a battery management system in a racing battery.This state of the art system is in place to keep the battery safe at all times.

The combination makes the Lithium Pros the most abuse tolerant battery in racing today and a great choice in marine. Good question. The reasons for moving to a Lithium Pros battery are many.1. Light weight.

Because of their 3x higher specific energy numbers, Lithium Pros batteries are inherently light and small. They are perfect for auto racing where every gram counts. If you are in an environment where weight is a premium such as racing, Lithium Pros is the way to go. If you are considering carbon fiber or titanium upgrades to your vehicle, you should have already made the switch to Lithium Pros.2. Higher power output. The Lithium Pros battery will deliver higher power during cranking and will hold a higher voltage during discharge than a comparably sized lead acid battery. That means a hotter ignition and faster starts.3.

Fast recharging. Lithium Prosbatteries can accept charge current at up to 5x faster than a lead acid battery. In many cases the Lithium Pros battery will be recharged in less than an hour. In fact our Pro Mod drag racing customers recharge in 15 minutes. A Lithium Pros battery cranks like no other and that is why they are so well accepted in professional drag racing, turning 800+ cubic inch engines every weekend!In fact many people are shocked at how well a small, ultralight Lithium Pros battery will start their engine.It is not uncommon for Lithium Prosbatteries weighing only one 1/3 rd to 1/6 th the original lead acid battery to easily start engines in warm weather.In cold weather (-4⁰F) the Lithium Pros battery should be the same actual amp-hour size of the lead acid it is replacing.

Lithium Pros batteries should not be used for engine starting under -4⁰F.For more examples of racers who are winning with the Lithium Pros battery, check us out on. PHCA – This is the Pulse Hot Crank Amps. This is the amount of amperage the battery can continuously deliver at room temperature for 0.1 seconds.

This is mainly provided as an indication of cranking ability.Again, a Lithium Pros battery will crank your engine like no other. We guarantee it!RC – This is the number of minutes the battery can supply 25A at room temperature and remain above 10.5V.WHR – This is the watt-hours which is simply the nominal voltage during discharge times the amp-hours. Shipping requirements vary based on the watt-hour rating of the battery.Volts – This is the nominal voltage during discharge all the way to 100% DOD.Max charge rate – This is the max charge amperage that should ever be applied to the battery. Typical battery chargers will not exceed this but your alternator easily could. It is important to consider this rating when matching a battery to your vehicle. The alternator will supply the amperage requirements of the vehicle including recharging the battery.

The amount of amperage available from the alternator beyond the vehicle’s needs should never exceed this rating.Max charge volts – This is the maximum voltage that should ever be applied to the battery during charging. In addition, this is the maximum alternator voltage set point. If your vehicle has a higher voltage set point, contact us for direction. Good question. The reasons for moving to a Lithium Pros battery are many.1. Light weight. Lithium Pros batteries are inherently light and small.

In fact, some models are so light they float! They are perfect for boating where weight savings equals fuel savings and shallower draft. The smaller the boat, the larger the advantage.2. Super Deep cycling capable. Lithium Ion batteries are the ultimate deep cycle battery. Compared with lead acid marine deep cycle batteries, Lithium Pros offers over 5 times the cycle life at 80% DOD. Lithium Pros batteries easily handle 2,000 cycles.3.

Fast and efficient recharging. Lithium Prosbatteries can accept charge current at up to 5x faster than a lead acid battery. In many cases the Lithium Pros battery can be charged in one hour! Your only real limit will be the capacity of the charger or alternator.How is this a big advantage? If you are running a generator or an engine and alternator to charge lead acid batteries you will save fuel and time charging Lithium Prosa lot of fuel and time!Please insure your battery chargers and alternators are gel battery compatible. Further, considering Lithium Pros batteries are 96% efficient at converting input energy into stored energy (vs. About 75% for lead acid), solar panels and wind generators are more productive.4.

Higher power output. The Lithium Pros battery will deliver higher power during cranking and will hold a higher voltage during discharge than a comparably sized lead acid battery. That means a hotter ignition, faster starts, and more watts for your accessories.5. Low self discharge.

Lithium Pros batteries can be stored for up to one year between boost charges without damage.For more examples of anglers who are winning with Lithium Pros batteries, check us out on. 12V Lithium Pros batteries can be charged with any three stage battery charger (Constant Current/Constant Voltage) without a desulfation mode that is made for “Gel” batteries. The battery charger must exit absorption mode and go to float mode at 1.25A or higher.Battery chargers for “flooded/maintenance free/standard batteries” should not be used. Battery maintainers and any float mode on a three stage battery charger must be limited to 13.6V or less.At no time should the battery charger exceed the max amperage and voltage rating on the battery label. 24V and 36V Lithium Pros batteries do require special chargers.Three and four bank chargers cannot be directly used to charge 24V and 36V batteries.For maximum battery life, a true lithium ion battery charger is recommended.

True lithium ion battery chargers have special algorithms to handle lithium ion batteries. They typically charge the battery differently when it is deeply discharged, rapid charge the battery when possible, and stop charging when the battery is accepting less than 1A to prevent over-charge.DualPro chargers can be reprogrammed for this purpose.

Contact DualPro for more information.Float charging should be avoided when possible. In general lithium ion batteries do not like to be held at 100% SoC. However, in applications where there is a constant parasitic load on the battery, float charging is allowed. MCA Eq – This is a rating unique to Lithium Pros and represents what the cell pack can deliver at 8V. This is given as a way to compare the engine cranking power of Lithium Pros to traditional lead acid batteries.Because of their high power output a Lithium Pros battery will deliver twice the power at 10.5V compared to a lead acid battery. For that reason, a Lithium Pros battery will crank your engine like no other.

We guarantee it!RC – This is the number of minutes the battery can supply 25A at room temperature and remain above 10.5V. This is the closest “apples to apples” comparison in capacity of a Lithium Pros battery vs. A lead acid battery.Max Amps – The pulse current the internal battery management system will allow without interruption.Continuous Amps – The current the internal battery management system will allow without interruption until the battery is completely discharged.WHR – This is the watt-hours which is simply the nominal voltage during discharge times the amp-hours. Shipping requirements vary based on the watt-hour rating of the battery.Volts – This is the nominal voltage during discharge all the way to 80% DOD.Max Charge Rate – This is the max charge amperage that should ever be applied to the battery.

Typical battery chargers will not exceed this but your alternator easily could. It is important to consider this rating when matching a battery to your vehicle. The alternator will supply the amperage requirements of the vehicle including recharging the battery.

The amount of amperage available from the alternator beyond the vehicle’s needs should never exceed this rating.Max Charge Volts – This is the maximum voltage that should ever be applied to the battery during charging.

There are some compact lithium-ion powered devices on the market that claim that they can start cars and trucks. Youtube is full of videos with reviews and people actually starting cars with them. And thousands of positive reviews on Amazon. Normally I'd buy one immediately, but given what I know about rechargeable lithium batteries, I just can't believe they are able to start cars.Someone did a teardown of one here:They advertise it as a '1000A' jump starter.

Some are even rated for 4000A!In the video you can clearly see the battery is a rechargeable pouch lithium-ion 12Wh battery. Probably 3 cells in series with 2Ah capacity. How can a 3S lithium-ion battery do even a pulse discharge of 100A, let alone 1000A?

The highest discharge cell I've seen on the market gives like 40A. No car will start with 40A. It just doesn't sound possible. But somehow thousands of people can start cars with it. Am I missing something here?

Did they patent some miracle technology? How is this possible?Another video, where somebody did a amp draw test:You can see on the clamp meter that the device puts out 350A for 10 seconds, and it stays above 8V during this time, so I guess it is able to start a car if the video is real. Around 40 times on a single charge. But I'm still puzzled about how can they do this with current li-ion technology?! How can such a small battery output 350A for 10 secs? The 1000A-4000A ratings I figured are part of the usual marketing bs, but 350A is still a lot for such a small li-ion battery.Another thing I noticed here:The internal battery has printed on it 11.V, 120C, 8000 mAh. That's just crazy.

Almost 1000A. I'm not aware of any LiPo with anything close to those discharge rates. If anyone knows one please post a link to the official datasheet with such specs. Yes, Lithium Ion batteries are capable of delivering the power required to turn over an engine.

The thing I am most experienced with is the kind of batteries you put in remote controlled devices, so I will use those for reference. For all intents and purposes they are basically a consumer-friendly version of the bare cells you will find in the devices you are talking about.How much power (simplify this down to current, since current is a function of the power, voltage and resistance, and for all intents and purposes the voltage and resistance is relatively constant) a lithium ion battery can deliver is a function of how much surface area the electrodes within the battery have. How much voltage the battery has is a function of how many cells it has.Because more surface area = effectively higher current capabilities, a larger battery pack generally means a pack that can deliver higher current.

The batteries discharge rate is measured as a function of its capacity as a results of this. A battery that is 10000mAh (10Ah) and has a 15C constant discharge rating - C standing for the capacity of the pack - means that the battery can be discharged constantly at 15 x 10A = 150A. In other words, you can (I can't suggest hooking one of the directly up to you car's battery, though).To add to this, the devices you are talking about aren't just a battery pack on it's own, they also include all sorts of charge circuitry and whatever else the manufacturer has put in them. As a result of this I would say it's safe to hazard a guess they aren't just battery packs like what I have described here (Even though we have come to the conclusion a battery pack on its own can deliver the power required for to turn over a reasonably sized modern engine), I would say they probably have a small capacitor bank alongside the battery.

Basically, capacitors can deliver significantly higher sustained current, but do not have much capacity. Think of a capacitor as a bucket, the cable from the battery to the capacitor as a hose, and the battery as a 50 gallon drum. You can only fill up the bucket as fast as the water moves through the hose, but once the bucket is full you can dump the entire bucket at once on whatever it is you need. Because a starter only needs it's peak current for a very short time, you could use a capacitor bank as a buffer from the battery to the starter to turn over the motor with very high currents.In short, a battery alone could turn over an engine relatively easily, but a battery alongside a bank of capacitors would do it without breaking a sweat. Throw in some circuitry for over-current protection and you can make the whole thing work perfectly with little worry of it going wrong and blowing up in your face.With regards to asking for a similar battery online. Its possible the manufacturer of the device is sourcing directly from a battery manufacturer to their desired specifications. This is a pretty heavy duty pack that I can't imagine has much mass-market appeal due to what would be incredibly rapid discharge times running at its rated load.

You can find 2S 8000mAh 60C lipos online, put two of these parallel and you effectively have a 4S 8000mAh 120C lipo. This is 1S over the one in the video but you get the idea. You could maybe team up a 1S and a 2S but i'd be worried of getting cells that are too different.

A least with 2 identical pack's you have more chance of them being near identical.It's also possible that the 120C rating is the pack 'burst' rating, not its continuous current rating. This is more likely as it's very easy to find 3S 60C 8000mAh packs with a burst rating of up to 120C, the manufacturer might be boasting the burst rating for this specific product as that is the bit that will matter with this, since the peak load with be short lived.If you want to see how high continuous load you can go this route, there's also products, thats 504A continuous current. At that rate you should be able to deliver 504A for 30 seconds before the pack is discharged. That's a lot better than the 350A for 10 seconds you are talking about in your question and again, this is just from hobbyist gear off the shelf. The manufacturer of these devices probably has a much wider range of suppliers to choose from, I can't tell if they are the producer of the battery pack in the device (since it's branded the same as the actual device) or if they are re-branding the packs, but it only strengthens the argument that these are packs produced specifically for this purpose. @Alex like I say, how much current a pack can deliver is a function of the surface area of the electrode.

In cylindrical cells like the 18650 as far as I am aware they 'coil' the electrodes to fit in the package, this obviously limits how much area they can squeeze in, especially since there are defined dimensions to stay within. With a pouch they can just make the electrodes lay out flat to the surface area of the pack, and make the pack as big or as small as they desire. That's why these packs can deliver better than your typical cylindrical cell.–Feb 20 '18 at 9:03. I also doubt the numbers they claim on the package but the real question is.

Can you start a truck with it? Yes you can!What you seem to forget is that the car or truck you connect this battery to has its own battery which can handle much higher current.

As soon as you connect the jump starter pack it will start charging the trucks battery. If the charge current is 10A you you might already have transferred enough energy after 30 seconds (there is enough to give 100A for 3 seconds from the trucks battery now, add to that another 20-30A from the jump starter and there you go).

Firstly: Of course the batteries can supply current far beyond the datasheet recommended levels.
