This massively useful electronic fuel gauge monitors each individual cell and measures the real-time current and remaining capacity of your LiPo battery before reporting the sensor data to your Multiplex M-LINK remote control. The automatic detection of the remaining capacity ensures safe operation even when using partially charged batteries. Part of Multiplex' intelligent Sensor Bus system (MSB) the LiPo saver can be connected in series with up to 15 other sensors direct to your Multiplex telemetry receiver - no additional sensor box required!
