Unique Selling Points:

  • The Rock-12-120 lithium battery LiFePO4 is safe and reliable whilst small and lightweight, with a long cycle life and fast charging.
  • Compared to lead-acid batteries, the volume and weight of Rock-12-100 are just around 1/3 and 1/2 respectively.
  • The built-in battery management system (BMS) provides multiple protection: over-charge, over-discharge, over-current, and over-temperature.
  • ROCK-12-120 will provide you with a minimum of 4000 complete charge and discharge cycles and still provide over 80% of usable capacity.
  • It can also be charged and discharged under a high current without affecting its expected lifespan.
  • The internal battery protection system is a high-tech innovative design made to protect lithium cells. Features include:
  • Low Voltage Protection Switch - Automatically disconnects at 10V
  • Over Voltage Protection Switch - Automatically disconnects at 15V
  • Short Circuit Protection Switch - Automatically disconnects
  • Reverse Polarity Protection Switch - Automatically disconnects
  • Internal cell balancing - Automatically balances cells
  • Charge Balancing - Independent balancing for multiple batteries connected in parallel or series.

Charging Sources:


Most factory 12V alternators on ICE (internal combustion engine) vehicles will sufficiently charge ROCK-12-120 and do not require any changes.


Most inverters have a battery-type switch that can either be selected to AGM for the closest setting to lithium or have a custom voltage setting that can be programmed to optimize your lithium battery.


You can set your inverter charger's voltage to charge bulk and absorb between 14.4V and 14.8V. The float should be set to 13.6V.

Standard Lithium Battery Charger:

Our batteries' internal BMS allows you to use a standard battery charger, in some cases a standard charger may not fully charge our lithium battery and you may need to purchase a lithium charger to get the full usable capacity from it.
