Battery Checker (ICC2010)

Compact Battery Checker for LiPo, LiHv, LiFe, and LiIon packs, supporting up to 8S. It keeps you informed with a bright 1.3-inch OLED display, four LEDs, and two 85 dB buzzers for loud, clear alerts. With three operating modes and an automatic alarm function, it makes it easy to monitor voltage status and catch potential issues before they affect flight or charging.

At just 54 x 30 x 9 mm and around 15 g, this checker is designed for field use. It reads per-cell voltages from 1.0 to 5.0 V with about ±5 mV accuracy and supports 1-8S packs. A voltage history histogram shows how the battery behaved during use, highlighting the lowest voltage recorded and the current voltage on screen. For on-board measurement, connect to the balance port on 1-8S packs starting from the BAT- terminal, and rely on an ARM 32-bit CPU for fast processing. A lower voltage threshold of 2.6 V per cell for 1S packs helps prevent over-discharge, making this device a practical tool for extending pack life and ensuring safe operation.
