The LipoMate is a high-precision measurement tool for Li-Poly batteries. It integrates the functions of measuring cell voltage, displaying battery power capacity, and balancing cells by displaying the balance status immediately. The small, yet surprisingly clear LCD contributes to its unique appearance. You will be alerted by a flashing alarm when cell voltages are low. Operation runs off the Li-Poly attached requiring no external power source. When the voltage difference between cells reaches 0.01V, the balancer will work until all the cells are balanced. The corresponding "V" will be flickering when it is balancing.
