General FAQ’s

Do I have to buy a special charger for Lithium Pros' batteries?

Not really. 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.

Can Lithium Pros' batteries be mounted in any position?

Sure.

Can your batteries take vibration?

Absolutely. Our customers range from tunnel boat racers to professional anglers. From the Baja to the drag strip to the Great Lakes, our products take a beating every day without issue.

How long will your batteries last?

It depends on your application but in general Lithium Pros batteries 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. See our instructions for more details.

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

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.

Why are they so expensive?

There are two reasons. First we use only the best high power lithium ion cells and these come with a cost, usually about 3~4 times higher than lead acid for the same capacity.

Second, the battery management system contributes much to the cost depending on its complexity. This system checks for high voltage, low voltage, over current, short circuit, or over temperature. If these conditions exist the battery management system will protect the battery from harm.

Can a dead lithium ion battery be jump started?

Lithium ion batteries are especially susceptible to cell damage when they are empty. For this reason, jump starting is not recommended. However it can be done with some special precautions and techniques. See the instructions for more details.

Racing FAQ’s

Why should I use Lithium Pros in racing?

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 Pros batteries 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.

Well, will it start my car?

Sure! 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 Pros batteries weighing only one 1/3rd to 1/6th 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.

Can I use my Turbo-Start or XS Power 16V Charger?

16V Lithium Pros batteries do 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 maximum voltage of 18.3V.

Therefore, 16V lead acid chargers should NEVER be used on a Lithium Pros 16V battery.

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 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.

Marine FAQ’s

Why Lithium Pros in a boat?

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 Pros batteries 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 Pros…a 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.

Do I have to buy a special charger?

Not really. 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.

Can they get wet?

Sure. They’re marine batteries. We assume they’re gonna get wet.

Can you explain the ratings?

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. In addition this is the maximum alternator voltage set point. If your vehicle has a higher voltage set point, contact us for direction.
