Description: Lipo battery is powerful and with high capacity for longer run time, but proper care is a must for all lipo battery. This device is make for a quick reference of your lipo battery with instant voltage reading. Besides, this device also act as a "dead cell" detector to indicate which cell is need to be replaced. Features: This high precision large screen balance discharger can solve the unbalance problem of battery after use. It can monitor each battery voltage, discharge protection function, and can balance each battery voltage, which is the best assistant of RC models. Specially designed for Li-Po battery and Li-Fe battery, accurately measure the battery total voltage and single voltage, balance several batteries in series, can be used to discharge battery for long time storage and avoid damage to the battery. The balancer can balance battery before or after charging and discharging, also can be used with a charger at the same time, for partial voltage and balance during charging. Large LCD display can show up to voltage of 6s batteries at the same time. Besides above function, this device also act as lipo balancer to condition your lipo before charge. And also a discharger to discharge the lipo when you play in field. This device can also testing your receiver battery with JST or JR type plug. Simply plug-in your lipo via the balance charger plug to this device and you will have all the information you needed. Easy to use! must have item for your lipo!
