Ultralife 12.8V 20Ah (256Wh) LiFePO4 Battery

The ULTRALIFE URB12200 is a high-performance 12.8V Lithium Iron Phosphate (LiFePO4) battery that offers significant performance advantages over traditional AGM and lead-acid batteries.

Internally, the URB12200 contains fifty-two LiFePO4 18650 size cells, connected in a 4-series, 13-parallel array to develop 12.8V 20.0Ah (256Wh). An electronic Battery Management System (BMS) provides protection against over-voltage, under-voltage, over-current, short circuit and over temperature. The BMS also provides a cell balancing function which enhances both safety and performance over the life of the battery.

The URB12200 is a drop-in replacement for AGM / lead-acid batteries in most cases due to its comparable charging voltage of 13.6V to 14.4V and has superior discharge performance in terms of energy delivered across both temperature and rate.

The URB12200 is certified to UN 38.3 (transport), IEC 62133:2012 (safety), and UL 2054 (safety). If your application requires the battery to be certified to IEC 62133-2:2017 please contact us.

The URB12200 can replace AGM and Lead Acid batteries in medical devices, UPS, emergency lighting, etc.
