Ultralife 6.4V 4.5Ah (29Wh) LiFePO4 Battery

The ULTRALIFE URB6450 is a high-performance 6.4V Lithium Iron Phosphate (LiFePO4) battery that offers significant performance advantages over traditional AGM and lead-acid batteries.

Internally, the URB6450 contains twelve LiFePO4 18650 size cells, connected in a 4-series, 3-parallel array to develop 12.8V 4.50Ah (29Wh). 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 URB6450 is a drop-in replacement for AGM / lead-acid batteries in most cases due to its comparable charging voltage of 6.8V to 7.2V and has superior discharge performance in terms of energy delivered across both temperature and rate.

The URB6450 is certified to UN 38.3 (transport) and IEC 62133:2012 (safety). If your application requires the battery to be certified to IEC 62133-2:2017 please contact us.

The URB6450 can replace AGM and Lead Acid batteries in medical devices, UPS, emergency lighting, etc.
