  • BMS stands for "Battery Management System" - the brain of our deep cycle battery. Our BMS protects your battery from most common causes of battery failure, such as temperature volatility or ground faults. The BMS regulates the amount of power taken out of the battery and acts as a shut-off system to protect the cells (and you) from unsafe operating conditions.
  • Suggest charge the battery with a battery charger or charge controller that is compatible with lithium iron phosphate batteries.When the battery voltage drops to OV, please activate the battery using an external charging source that has a lithium battery activation function(or using 12-15V power adapter).
  • Battery Terminal: M6, 1/3 inch diameter of the screw, fit for inner diameter of tray cable 1/3 inch to 1/2 inch, suitable for most battery connecting cables; Battery Size: 12.83*6.69*9.13 inch. Please match the size to perfect fit if install it in a battery box.
  • Lithium Iron Phosphate (LiFePO4): Lithium phosphate cells are incombustible in the event of mishandling during charge or discharge, they are more stable under overcharge or short circuit conditions and they can withstand high temperatures without decomposing. When abuse does occur, the phosphate based cathode material will not burn and is not prone to thermal runaway. Phosphate chemistry also offers a longer cycle life.

Product Features

  • Specification - Voltage: 12v; Amp: 16Ah; Dimension: 5.94*3.9*3.7inches (L/W/H); Weight: 1.8kg/3.97lbs, Terminal: F2.
  • 2000 Charging Cycles - Lead-acid batteries last 100-300 cycles is a lot more typical while lithium-iron batteries will go 2000 cycles with no problem. If being used daily, an AGM will need to be replaced approx. 6 times before the LiFePO4 needs replacing. Lithium batteries can be fully discharged without risk and without loss of future capacity as well.
  • Flat Discharge - LiFePO4 technology gives a very flat discharge curve which means sustained power to the end of the cycle. If you are powering lights they will remain brighter for longer, giving you sustained performance
