Model KS-ARC120 ARCTIC SERIES ultra low temperature 120AH 12V lithium leisure battery

The KS-ARC120 Arctic LiFEPO 12V 120AH is a ultra low temperature high current leisure/equipment battery featuring an advanced internal cell construction using a unique bolt/cradle fixing system. Each bank is encased in an electrically self-heating silicon rubber blanket which is controlled by the smart battery management system. Both normal charging ability and discharge is possible from minus 30 degrees Celsius.

Automatic monitoring of the central temperature for each cell bank enables the smart BMS to maintain a safe operational temperature, regardless of the real time external ambient temperatures. The battery continue to charge or discharge normally upon demand. The system if fully autonomous with no required user intervention or any additional wiring. When charging, additional power is taken from the charger (via the battery poles) to provide heat. The battery may be externally lagged to improve the efficiency making additional power available for charging from any standard 14.4/14.6 cc/cv charger.
