Phocos BCM AA battery charger is an innovative AA NiMH, NiCd battery charger. Designed specifically for photovoltaic systems, it can be used with any 12 V battery. BCM charging current is small and constant, charging voltage is intelligently controlled, it can effectively prevent overcharging and significantly extend battery life.
The Phocos BCM is a compact AA battery charger designed for photovoltaic systems. It can charge up to four AA cells simultaneously, each cell being individually controlled, allowing mixed types and capacities. The charger provides smooth constant‑current charging, excess‑energy management, and LED indicators for power status.
Technical specifications include a rated input voltage of 12 V (10.5‑15 V range), four 1.5 V outputs, a maximum charge current of less than 60 mA per cell, and support for 500‑2,500 mAh batteries. Charging times range from ~14 h for 500 mAh to ~70 h for 2,500 mAh. The unit measures 80 × 100 × 32 mm, weighs 180 g, and operates from –40 °C to +50 °C. It mounts on a standard DIN rail.
