With an easy-to-read LCD display and built-in safety features, the convenience and accuracy of this tool can’t be beat. The battery checking function precisely reviews the voltage of each cell of a lithium polymer pack while displaying the remaining total capacity. The balance operation equalizes the individual voltages of each cell until the difference between each reaches 0.01 volts or less. Although most LiPo packs' balancing ports will plug directly into the LiPo Checker, an adapter for Thunder Power and Flight Power style plugs is also included. Please be certain only to use lithium polymer battery packs up to 6 cells (6S).
