Feature: 1. Great Balance: By detecting the unbalanced voltage difference between adjacent battery strings, high voltage is transmitted to low voltage to achieve voltage balance between battery strings. 2. Reliable Uses: Can automatically detect and start to balance the voltage when the quantitative difference is reached. 3. 2 Input Ports: Also supports 2.0 and 2.54 dual row input ports, very convenient to connect various battery pack port. 4. Safer Working: The aluminium alloy shell is waterproof, which can prevent electric leakage and better protect circuit. 5. For Batteries: Suits perfectly for ternary polymer lithium battery and for LiFePO4, has high efficiency and reliability. Specification: Item Type: Battery Active Equalizer Material: PCB + Aluminium Alloy Applicable Battery Type: For ternary polymer lithium battery, for LiFePO4.
