features and functions. Users could set the terminal voltage by themselves and connect it to PC for PC control and firmware upgrade. What\'s more, users could also use it as lithium battery meter and battery internal resistance meter. There are automatic charging current limit, capacity limit, temperature threshold and processing Time limit which makes the charger safer than V1. SKYRC B6AC V2 is a high-performance, micro processor control charge/discharge station with battery management suitable for use with all current battery types, with integral equalizer for six-cell Lithium- Polymer (LiPo), Lithium iron phosphate(LiFe) and Lithium-Ion (LiIon) batteries; maximum 6A charge current and maximum 50W charge power. It can be powered by 11-18V DC source or from 100-240V via the built in switch-mode power supply. Features: SKYRC B6AC V2 employs an individual-cell-voltage balancer. The charger can store up to 10 different charge/discharge profiles for your convenience. The user can check battery\'s total voltage, the highest voltage, the lowest voltage and each cell\'s voltage by this charger. Automatic Charging Current Limit: Capacity Limit, Temperature Threshold, Processing Time Limit. The charger allows user to change the end voltage. (for expert user only)
