Product Description

12.8V 38.4 (492Wh) Lithium Iron Phosphate Smart U1 Battery

ULTRALIFE’s new URB12400-U1-SMB Lithium Iron Phosphate smart battery offers incredible performance in a wide range of transportable and stationary equipment, including medical carts, delivery robots and UPS systems. The inclusion of Ultralife’s SMART CIRCUIT™ battery management electronics provides the user with accurate runtime information in addition to a balancing and protection system which maximises both safety and performance.

The URB12400-U1-SMB is specifically designed to replace and outperform lead acid batteries. The tough, bi-coloured UL 94V-0 flame retardant polycarbonate case ensures internal cells and electronics are protected at all times and unlike a lead acid battery the URB12400-U1-SMB can be mounted in any direction and does not require charging in a vented area. When used in a cyclic application more than 2000 cycles are possible, making it a truly ‘fit & forget’ proposition for many applications.
