and high quality. Equalizer is used for the 12V battery is which are connected in series to keep battery voltage balance. 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. The maximum equalizing current can reach 4A, and the intelligent equalizing speed is fast. It protects each battery, prolongs the service life of the battery pack, and increases the endurance. When the battery voltage difference is large, equalizer automatically adjusts the current to reduce the equalizing current and pulse duty cycle, which is more intelligent and efficient. Built in MCU chip, multiple protection integrated management scheme, more accurate data acquisition and faster processing. Anti reverse connection protection function: Effectively protect the equalizer and prevent damage to the equalizer and battery caused by incorrect connection of positive and negative electrodes. The equalizer is widely used and compatible with various battery types:It is suitable for ead-acid, Gel, lithium iron phosphate, ternary lithium and other battery types. Solid heat dissipation: High quality metal aluminum shell design, using solid heat transfer adhesive, greatly increases the heat dissipation speed. Battery Standard voltage:24V Compensation Current:0-4A Standby Current:Less than 3mA Operating temperature:-20 ℃ - +55 ℃ Protection:Reverse Polarity Protection Note:Due to dif
