EVPEAK CQ3 LiPo Battery Balance Charger,100Wx4 10A Four Channel LiPo, LiHV, Life, NiCd, NiMh Battery Balance Charger Discharger The power source can be 11-18V DC input, it can be powered up at any plance with a 12V car battery or 110V or 220V AC input. The power supply is built in and users could connect the AC Power cord to the main AC socket directly. Whats more the AC input voltage is 110V or220V so that the users could use charger all over the world and dont need to worry about any damage caused by improper input voltage. Adjustable cutoff voltage; During the process of discharging, CQ3 Charger can monitor and balance each cell of the battery individually. Error message will be indicated and process will be ended automatically if the voltage of any single one cell is abnormal. The charging capacity is always calculated as the charging current multiplied ba time. if the charging capacity exceeds the limit, the process will be terminated automatically when you set the maximumvalue. Purposes to charge lithium battery varies, fast charge reduce the duration of charging, whereas store state can control the final voltage of your battery, so as to store for a long time and protect useful time of thebattery Discharge mode: CC/CV optional;Pre charge function;Temperature control fan;Firmware upgrade cia USB kit;Biuld-in 500W SMPS
