This is one of our best-sellers! Finally a (more) affordable Lithium-ion battery, made by Battle Born, a Reno, Nevada, based company. Also see our Finding Happiness with Lithium-Ion article, explaining the care and feeding of these batteries.

Just 1/3 the weight of lead-acid, zero maintenance, and thousands more cycles vs. lead-acid. Battle Born Batteries offer an economic alternative when space and weight matter, such as for boat trolling motors and RV applications.

Battle Born lithium-ion batteries are true deep-cycle batteries, they can repeatedly be discharged a full 100% without damage. The battery has a build-in battery management system (BMS). The BMS allows them to be charged with regular solar PV charge controllers, with the same settings as for any other sealed battery (such as AGM batteries). The BMS also takes care of protecting the batteries from over- and under-charge, low Voltage disconnect, over-current, and automatic balancing of the cells.

Charge settings for Battle Born batteries:

  • Bulk/absorb = 14.2 – 14.6 Volt, with 14.4 Volt ideal
  • Absorb time = about two hours, or until the current drops to 5A or less.
  • Float = not needed, set to 13.6 Volt or less
  • No equalize, or set to 14.4 Volt if it can’t be disabled
  • No temperature compensation, set to 0
  • Charge rate of 25 – 30A or less is preferred for longevity, though up to 60A is possible
  • Battery has to be warmer than -4 Centigrade (25F), or the BMS will not allow charging, discharge works fine up to -20C (-4F)

The maximum discharge rate is 60 Amp continuous, 100 Amp for 30 seconds, and far more for 1/2 second.

Battle Born batteries can be connected in series and parallel to increase the bank Voltage and Ah rating. For example, two BB5012 batteries in series will make a 24 Volt / 50 Ah battery bank. Two in series and two in parallel will make for 24 Volt / 100 Ah etc. Any number of batteries can be connected in series/parallel. Parallel strings of batteries will increase the charge and discharge rates (i.e. 100A for two parallel strings etc.). Ask us if you have any questions about properly sizing a battery bank.

Battle Born batteries use LiFePO4 chemistry (Lithium-Iron-Phosphate). This is very stable and is not sensitive to spontaneous combustion, in comparison to laptop and cell-phone lithium-ion batteries (which use Lithium-Cobalt-Phosphate chemistry). The cells have build-in protection for over-pressure, over-temperature, contain a fire-retardant in the electrolyte and casing, and have a stainless steel jacket. These are very safe batteries!

Because lithium-ion batteries can be discharged to 100% DOD, and this can be done for more cycles, a smaller battery bank can suffice vs. lead-acid. Since there is no off-gassing these batteries can be mounted indoors.
