CSR Li-Poly Balancing Charger will handle 1-4 cell packs and eliminate the danger of over-charging out-of-balance packs. Charging (from 0.5 - 2.0 amps) and balancing take place simultaneously. Input voltage is 11.5 - 14 volts. This charger has a fuse and cooling fan to insure long life for the internal electronic components. Two 7.4 volt (2 cell) packs can be charged and balanced at the same time. Additional connectors with wire leads are supplied so you can charge any brand of battery.
