Feature: 1. HIGH EFFICIENCY: The lithium battery balance board has high efficiency capacity transfer, high accuracy 5MV whole group balance, not adjacent balance. 2. SLEEP PROTECTION: If the working voltage is too low, it will automatically stop and enter the sleep state, and the standby power consumption is less than 0.1mA. 3. APPLICABLE BATTERY: Suitable for active balancing of 4S lithium battery packs, suitable for ternary lithium, lithium iron phosphate and lithium titanate batteries. 4. WORKING PRINCIPLE: Adopt capacitive working principle to achieve energy transfer balance, scan the entire battery voltage, and transfer high voltage electricity to low voltage. 5. VOLTAGE AND CURRENT: The equalizing voltage is 1.8V‑4.5V, and the equalizing current is 0‑5.5A, the greater the battery voltage difference, the greater the equalizing current. Specification: Item Type: Lithium Battery Balance Board Balance Voltage: 1.8V-4.5V Scope of Application: For Ternary lithium, lithium iron phosphate, lithium titanate battery Balance Current: 0-5.5A, the greater the battery voltage difference, the greater the balance current. Package List: 1 x Battery Equalizer Board 1 x Connecting Line
