Description: This battery equalizer is used to maintain the charge and discharge balance between each battery in series connected battery. It can compensate for the battery in both directions. With reverse polarity protection, the low voltage disconnect can provide longer battery life time. It can also be connected in series for a long time in the battery, so as to automatically maintain the balance of the battery state. Intelligent battery voltage equilibrium system keeps batteries in heath and saves battery lifespan.
