Saft has already supplied power sources for the Land warrior program. The company based its design on the high performance, compact format MP series prismatic Li-ion cells, which are already in use with many existing military radio communications customers. A key advantage of the MP cell is its unique rectangular shape which gives it an extremely high capacity, compared to conventional cylindrical cells – a single prismatic cell has some 20 per cent higher volumetric energy density than an equivalent pack of cylindrical cells. The battery performs in an operating temperatures range from -30°C to +60°C (in discharge), and will retain 95 per cent of its charge after one month’s storage. These batteries are supplied in a ruggedized, water resistant metal housing, complete with protection circuitry, state of charge indicator and a commercial off the shelf connector.
