Frequently Asked Questions: 

Which Direction do I have to mount my Feather-Lite Batteries® Unit?

Your Feather-Lite Batteries® Unit can be mounted in any direction as long as it's safely secured.

How do Feather-Lite Batteries® handle severe vibration commonly found in racing?

Feather-Lite Batteries® are designed to deal with the severe conditions that racing can put them through, vibration and shaking are no problem. Our batteries have been put through the worst Top Fuel can throw at them to racing on paddle tires in the mud.

So Many Lithium Batteries Blow up or Catch on Fire, will Feather-Lite Batteries®?

  • Feather-Lite Batteries® does not use the same materials to make our batteries that are used in other batteries that have had explosion or fire risk. 

  • The term Lithium-Ion refers to a Lithium battery that can be recharged, not the chemical make-up of the battery’s cells. There are many variations of cell construction that fall under Lithium, varying from extremely volatile to inherently safe materials. The price of these materials is also directly paralleled to the danger level of the cell construction.

  • From the cell design to cell construction Feather-Lite Batteries® has agonized over the details to make sure their batteries are as safe as possible. This is also why any battery known to be used in anything other than a "Total Loss" system within a race vehicle is protected with an extra layer of FLB circuitry protection system which acts as the front line between the battery cells and the outside world of uncontrollable factors.

Will This Tiny, Lightweight Battery really Start and Run my Race Car?

Your Feather-Lite Batteries® unit will start your car better than lead acid/ AGM batteries and most every lithium battery you probably had. If you choose a comparable or properly sized unit for your application, you will be pleasantly surprised.

Can I use my current Charger, It's a Smart Charger?

Feather-Lite Batteries® chargers have a specific charging algorithm and test cycle used to charge them SAFELY and FULLY. If you have a charger from your lead acid or AGM you CANNOT use it to charge our batteries. A lead acid battery does not charge in the same manner as a Feather-Lite Batteries® unit.

I have a Lithium Charger already do I need to buy one of Feather-Lite Batteries®?

If you have a Lithium Charger from another manufacturer that you want to use, Feather-Lite Batteries® will NOT warranty your unit fully or possibly at all, since we do not know the condition or charging algorithm of your charging unit. Charging with another company’s charger will  BE AT OWNERS OWN RISK AND AT COST TO THE OWNER FOR ALL EXPENSES AND DAMAGES INCURRED!

Whats the Life Expectancy out of a Feather-Lite Batteries® unit?

Feather-Lite Batteries® expected life expectancy is 7-10 years plus. Key factors that affect the life expectancy of batteries is depth of discharge (DOD), operating temperature, & ambient temperature during charging. We calculate the life expectancy of the battery at 90% depth of discharge, which in normal conditions can be recharged 2500 times before battery performance will see any change. In markets that the battery is exposed to hotter than average or colder than average temperatures during use, charging results may vary slightly. Also, if the depth of discharge is less than 90%, the life expectancy should increase. (Depth of discharge is how far drawn down into the reserve the battery gets during use.)

How do I know what battery I need?

The simplest way to figure out what battery you need from the Feather-Lite Batteries® is to check the numbers on the battery you will be replacing and match the specs to what series you are looking at.  If you still are unsure or have questions you can reach out to one of our customer service members via chat, email, or by phone and they would be glad to offer you a suggestion to suit your needs.

What do all these terms mean?

Feather-Lite Batteries® terms:

  • Lithium-Ion - Means rechargeable Lithium battery and does NOT identify the chemical makeup of the battery.

  • State of Charge (SOC) - Simply states how charged the battery is.

  • Depth of Discharge (DOD) - How depleted the battery reserve is after standard use.

  • Reserve - Is the capacity of the battery. (otherwise stated as Ah)

  • Amp Hours (Ah) - This is the capacity of the battery (the amount of power it can store.) Expressed in how long it will run @ a certain amperage drain. Typically stated at 20-amp load.

  • Nominal Voltage - The voltage of the unit at its rested state, meaning where it normally levels off at. Not just off the charger.

  • Cranking Amps (CA) - This is a term typically used in Lead acid or AGM batteries it is the number of amps the battery can discharge for a set time of 15 seconds.

  • Cold Cranking Amps (CCA) - This is also a lead acid/ AGM term. It is the number of Cranking amps a battery can produce for 15 seconds at freezing or below temperatures.

  • Pulse Cranking Amps (PCA)This is a term typically used ONLY in the Lithium battery market. All it shows is what the absolute peak cranking amp number that the battery can reach for a 1-2 second load.

I just can't justify paying that much for a battery?

Feather-Lite Batteries® understands that the upfront cost is much higher for one of their batteries than a typical lead acid battery. And if the weight savings isn't what you are interested in them for, which is the cheapest way to shave pounds off your project, Then maybe looking at it as a simple math equation will help justify the cost difference. 

If you buy a lead acid/AGM battery at a cost of $250 USD,  at best it is good for 400-500 charge cycles and a Feather-Lite batteries® unit is good for up to 2500 charge cycles, you will have to buy 5-6.25 batteries over the same time frame that one Feather-Lite Batteries® unit is good for.

So, $250*5= $1250 OR $250*6.25= $1562.50 

Never mind the bad days when you go to turn the key and it goes Click, Click. Yes, the upfront cost is more but in the long run it is a cost savings.

Can Feather-Lite Batteries® get wet?

Feather-Lite Batteries® ARE capable of getting wet (CANNOT BE SUBMERGED IN WATER!) all battery units are sealed to an extent. Feather-Lite Batteries® Marine Series batteries are sealed with a different process that is specific for the use on water, where they are expected to be wet frequently. This process is also available on other batteries but you will have to contact a sales rep to request this service if you plan on using something like a race battery in race boat for instance. An extra fee and lead time may incurred for this process.
