Cold Temperature Storage of Battle Born Batteries


Recommended Posts

With Winter coming on, there have been many posts about cold weather storage of Lithionics batteries in newer Oliver trailers with solar packages.   Many of us have converted from lead/acid batteries to Battle Born brand LiFePOH.   In their storage instructions, they reference extreme conditions, but don’t specify what those temps are.   I thought that would be useful info to some who might live or camp in very cold climates, so I called Jacob at BB Tech Support.  He explained their batteries can be safely stored down to -10F (internal  battery temp), but they should be charged to 100% and disconnected.  Below that temp, they recommend warmer storage.   

The following are specific details from the BB manual about safe operating & charging temperatures:

  • The BMS will not allow a charging or discharging current if the internal temperature of the battery has reached 135°F (57.2°C).
  • The BMS will not allow a charging current under 25°F (-3.9°C) but will continue to discharge down to -4°F (-20°C).
  • NOTE: The BB10012|BB10012H has an operating temperature range of -4°F (-20°C) to 135°F (57.2°C).
  • How to Properly Store Batteries
    • We recommend bringing the Battle Born batteries to a 100% state of charge. Then, disconnect the battery from any loads by removing the negative cable from one battery. On average, the batteries lose approximately 2-3% capacity per month. This is subject to increasing if stored in extreme environmental conditions.
