Why Lithium?

Why Lithium Pros? Good question. The reasons for moving to a Lithium Pros battery are many.

1) Light weight. Because of their 3x higher specific energy and energy density numbers, Lithium Pros batteries are inherently light and small. They are perfect for auto racing where every grams counts.

If you are in an environment where weight is a premium such as racing, boating, flying, or anything carried by hand, Lithium Pros is the way to go.

2) Super deep cycling ability. A Lithium Pros battery can be thought of as the ultimate deep cycling battery. Depending on the depth of discharge, a Lithium Pros battery can do 5x as many cycles as a lead acid. Also the Lithium Pros battery can easily handle 80% Depth of Discharge (DOD) whereas the lead acid is good only for 50% DOD. The deeper you go, the more the Lithium Pros battery will outperform the lead acid battery.

If you are replacing a lead acid battery in two years or less due to deep cycling damage, you will save money in the long run moving to a Lithium Pros battery.

3) Fast recharging. Lithium Pros batteries can accept charge current at up to 5x faster than a lead acid battery. What's more, the charge efficiency is about 97% for the Lithium Pros battery in contrast to 75% for lead acid batteries. This means less mechanical energy is wasted in the process of recharging.

Well, will it start my car?

Sure! Lithium Pros battery batteries can be configured for engine starting. 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 Pros battery batteries weighing only one 1/3rd to 1/6th the original lead acid battery to easily start engines in warm weather. In cold weather (-20?C) the Lithium Pros battery should be the same actual Amp-hour size of the of the lead acid it is replacing. The challenge here is making a battery management system that can handle the out-rush current of the starter and the in-rush current from the alternator during heavy recharge.

One thing to keep in mind though is that here at Lithium Pros we are focused on making the lowest ESR lithium ion batteries on the market. That makes a huge difference compared to our competitors when you start the engine. 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!

I heard these batteries were unsafe and a fire hazard. Will they blow up?

Every battery of any chemistry has the potential to fail, sometimes catastrophically. In addition, lithium metal batteries which are more volatile, are not to be confused with lithium ion batteries. However our lithium ion chemistry is the safest on the market. Remember, there are many lithium ion chemistries and variations. Some are more volatile than others but all have made advances in recent years. Also note that all lithium ion batteries undergo rigorous UN testing before they can be shipped worldwide further insuring their safety.

There are many choices for cell suppliers worldwide with a wide range of expertise and equipment. We are using lithium iron phosphate cells for their intrinsic safety and these cells are produced by a licensed PhostechTM manufacturer.

Why are they so expensive?

There are two reasons. First the cost of the cells is high, usually about 3~4 times higher than lead acid for the same capacity. This will no doubt come down as worldwide supply goes up.

Second, every lithium ion battery has (or should have ;D ) a battery management system. This system checks for high voltage, low voltage, over current, short circuit, or over temperature. If these conditions exist the BMS literally disconnects the battery from its load and turns off the output terminals. This mini-computer inside a battery adds cost especially if it is sized to handle your starter! For this reason larger lithium ion battery packs are usually less expensive per watt-hour than smaller ones.

Do I have to buy a special charger?

Not really. 12V Lithium Pros batteries can be charged with any voltage regulated battery charger without a desulfation mode. Trickle chargers should not be used. AGM type battery chargers are highly recommended since the finishing voltage is regulated and typically lower than for a flooded lead acid battery. At no time should the battery charger exceed the max amperage and voltage rating on the battery.

16V Lithium Pros batteries require a special charger simply due to the fact that 16V lead acid batteries charge at a higher voltage. Most 16V lead acid chargers on the market charge at 19.6VDC. This is 1.3V higher than the max. voltage of 18.3V Therefore 16V lead acid chargers should NEVER be used on a Lithium Pros 16V battery.

For maximum battery life, a true lithium ion battery charger is highly 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.

Can they be mounted in any position?


How long will they last?

Depends on your application but in general Lithium Pros batteries operating within their accepted voltage range, at 50% 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.

Can you jump start a dead lithium ion battery?

No. Lithium ion batteries are especially susceptible to cell damage when they are empty. A good lithium ion charger will actually "soft start" and roll the output current back when it detects a lithium ion battery at a very low SOC. This being the case, jump starting would send an uncontrolled amperage into a very low lithium ion battery. Bad idea. Don't do that. Use a lithium ion battery charger or a 12V AGM charger at its lowest setting (1~2A) and slow charge the Lithium Pros battery back to 20% SOC. After that it can be charged like normal.

Can you explain the ratings?

PHCA This is the Pulse Hot Crank Amps. This is the amount of amperage the battery can continuously deliver at room temperature for 5 seconds. This is mainly provided as an indication of cranking ability. Again, a Lithium Pros battery will crank you engine like no other. We guarantee it!

Important Terms

RC This is the number of minutes the battery can supply 25A at room temperature and remain above 10.5V.

AHR (PB EQ) This is 3x the actual amp hour rating at a five hour discharge rate. Considering Lithium Pros batteries have 1/3 the internal resistance of a similar capacity lead acid battery and they can be safely discharged to 90% DOD and they hold a higher voltage during discharge, a Lithium Pros battery in a starting application can replace lead acid batteries of 3x the size in amp-hours. Therefore the AHR (PB EQ) is a way of comparing the starting work this battery can do vs. a lead acid battery. If you have a 30Ah lead acid battery in the vehicle today, you can safely replace it with a 30AHR (PB EQ) battery from Lithium Pros in most cases.

In a deep cycle, slow discharge application such as trolling or in total loss systems (no alternator), you can safely replace a lead acid battery with Lithium Pros battery at a 2x rate. i.e. if you are replacing a 50Ah lead acid battery you will need a 25Ah, or 75AHR (PB EQ), Lithium Pros battery.

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 rating is important. 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.

How can you determine this? You could get precise and measure it with an inductive DC clamp meter or by putting a large ammeter in line with the battery, discharge it 20% or so, and start the vehicle. The ammeter should show the current flowing from the alternator into the battery. (When you are connecting them, be sure to measure the current flowing into the battery only. You do not need to know the current flowing out of the alternator to other loads like the ignition system, fans, lights, etc.) That will give you the exact answer.

If your vehicle has the OEM sized alternator still installed, a simple guide is to take the alternator's rating and divide it by two. In general, this will represent the current typically available for battery recharge after the other needs of the vehicle are met. (i.e. Using this guide, a Chevy Tahoe with a 124A alternator would have about 62 amps available for recharging the battery.) Short bursts of amperage greater than this max charge rate of less than seven seconds that are simply replacing the energy used for a starting event are not a concern. On the other hand, recharging the battery from anything below 20% DOD with amperage beyond the max charge rate will overheat and damage the battery, will be viewed as abuse, and may void the warranty. If in doubt, buy the next size up.

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.
