Single cell connection cords for lithium batteries with JST-EHR plug system. For automatic conversion of lithium batteries. Suited for robbe chargers & equalizers. Compatible with Graupner & Kokam. For charging, the connection of Equalizer is connected at this voltage sensor in order to individually balance each of the cells. Moreover each cell is checked for maximum voltage & if necessary, the charging is stopped in order to prevent overcharging. The voltage sensor connection is useful even in convenient operation (discharge), a MC-Balancer (No. 8636 (7S) or No. 8643 (14S) controls the individual cells for low voltage & if necessary, directs some current back for discharging & to prevents damage to the lithium cells.
