Versatile: The cell counter displays estimated voltages for LiPo, LiFe, and Li-ion battery packs (2-7 cells) as well as single cells, and for NiCd and NiMH batteries (4-7 cells) used in TX and RX systems. The battery capacity checker quickly estimates the remaining capacity of lithium battery packs and indicates if recharging is needed before use. Battery type: NiCd / NiMH (4 to 7 cells), lithium type (2 to 7 cells) Display mode: Battery cell voltages, total voltage, lowest cell voltage, voltage deviation between highest and lowest cell, and remaining battery capacity Application: Designed for checking batteries. Provides a convenient way to read cell voltage. High quality, safe, durable, compact, and easy to use. Lightweight with reliable performance.
