Features Function: This high-precision large-screen balance discharger can solve the imbalance problem of the battery after use. It can monitor the voltage of each battery, has discharge protection function, and can balance the voltage of each battery, which is the best assistant for RC models. Precise Design: Specially designed for Li-Po batteries and Li-Fe batteries, accurately measure the total voltage and single voltage of the battery, balance multi-series batteries, and can be used for long-term battery discharge to avoid damage to the battery. Safe Charging: The balancer can balance the battery before and after charging and discharging, and can also be used with the charger to divide and balance the voltage during the charging process. Unique Design: The large LCD display can display the voltage of up to 6s battery at the same time. The device can also test your receiver battery with a JST or JR type plug. Ease of Use: In addition to the above features, the device can also act as a fat balancer, regulating your fat before charging. There's also a discharger to drain fat while you're playing in the wild. Just plug your lipo into this device via the balanced charger plug and you will have all the information you need. Easy to use! 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. Specifications: Supported Battery Type: Li-Po/Li-Fe 2~6 cell (nominal voltage 7.4V~25.2V use differential voltage connector) Receiver Battery: 1.2V~12V DC (unlimited battery type, but should externally connect to 7.4V~25.2V, use JST connector) Balance Voltage Set Range(lower limit): 2.0V~3.9V(default 3.3V) Discharge Voltage Set Range(lower limit): 3.0V~4.2V(default 3.9V) Discharge Current(4.0V/Cell): About 450mA Support Battery Connector: Common battery linear connector, JST plug connector, Rx connector Size: 9.3*6cm/3.7*2.4in Weight: 79g(approx.)
