Main purpose: Battery equalizers are used to maintain the charge and discharge balance between cells in the battery pack and are widely used in battery configurations such as cars, boats, motorcycles, and solar panels. Features: 1. Battery protection: The battery equalizer has an intelligent voltage compensation system to keep the battery in an idle state and automatically shut down when the voltage is insufficient to extend battery life. 2. Automatic balancing: The battery equalizer can be connected in series with the battery for a long time to maintain the charge and discharge balance between the batteries in series. 3. LED display: The battery equalizer can display real-time voltage through the LED screen, and the voice control display reduces energy consumption. 4. IP67 protection level: This battery equalizer is made of PCB plastic, which has high flame retardancy and impact resistance, is not easily broken or damaged, has a waterproof level of IP67, and has a long service life.
