High-quality 3-in-1 battery balancer, discharger, and cell monitor. This balancer can be used for LiPo and LiFe batteries. It measures the cell condition and can be used as a balancer to optimally balance the cells. In discharging mode, the cells can also be prepared for winter storage, for example. The cell charge status is displayed throughout the balancing process, allowing for quick detection of faulty cells before risking a crash during flight. Supported battery types: Li-Polymer / Li-Fe: 2 - 6 cells / 7.4V - 22.2V. Balance setting range (lower limit): 2V - 4.2V (preset at 3.3V). Discharge setting range (lower limit): 2V - 4.2V (preset at 3.9V).
