5-Level LiPo Battery Voltage LED Indicator (2S/3S/4S)

Push-button battery level indicator for LiPo and other lithium packs: a row of five LEDs shows roughly how much charge is left. It suits battery boxes, field chargers, FPV ground stations and RC models where a full voltage checker is more than you need. Choose the 2S, 3S or 4S version to match your pack.
