Sterling Lithium Batteries 12V

Please Note: Due to shipping restrictions these batteries can only be purchased in our stores

12V Lithium Iron Phosphate Batteries with BMS and safety shutdown.

Unlike traditional lead acid batteries, which have a usable capacity of approx. 50%, Lithium batteries have a 100% usable capacity. Lithium batteries are not as affected by depth of charge and discharge resulting in an approximately 20 times greater life expectancy. Plus, they are also less than half the weight of the equivalent lead acid, which means that the available energy per weight ratio is 4 times better with lithium batteries.

These Lithium Batteries from Advanced Mobile Power Systems by Sterling Power have a built-in Battery Management System and Safety Shutdown feature.


Battery Management System and Safety Features:

  • Automatic fault recovery system
  • Internal cell thermal safety fuse
  • Flame retardant electrolyte
  • Fire retardant plastic case
  • Explosion proof stainless steel cells
  • Automatic battery protection system – internal
  • Automatic low voltage - disconnects at 10V
  • Instant automatic short circuit protection
  • Protects the battery when high/low voltage, too high current, too high temperature


Battery Specifications:

  • Positive & negative terminals with bolt/thread & washer
  • Prismatic cell type
  • LiFePO4 12V (nominal).
  • Max charge V=14.8V, Recommended =14.6V, Float V=13.8V
  • Cut off voltage: 10V, Cut off temperature: 50°C
  • Charge Curve style: CC/CV
  • Operational temperature: -30 to +60°C
  • Internal consumption: Operational = 10mA, Dormant 0.1mA

CHARGING - Lithium Batteries MUST be charged using the correct voltage profile and current rate.

The following recommendations should be followed:

For DC to DC charging (i.e. from an alternator), charging must be via a Battery to Battery charger (see Product Code: 130099). Either 30A (for 1 battery) or 60A (for 2 batteries). For AC to DC charging (from mains or generator), charging can be via a Pro Charge Ultra 12V 50A or smaller battery charger (see Product Code: M130066)
