Suitable - Use for LiPo / LiFe / Li-ion / NiMH / Nicd / battery, it can also display the voltage of each cell, so you know when they need to be balanced. Battery Capacity Checker - It can display the estimated capacity and voltage for battery. Use this function to quickly check if your battery requires charging before use. LCD - The screen displays highest and lowest voltage of cells and the difference between highest lowest cells. Display Mode - Battery cell voltages, total voltages, lowest cell voltage, highest cell voltage gap between highest cell voltage and lowest cell voltage, remaining battery capacity(%). Balance Function - Optimize your batterys performance, and extend the overall lifespan, by ensuring the individual cells are balanced.
