Feature: 1. BALANCE CURRENT: When the equalizer board is connected to the battery, it starts equalization work, the equalization current is 0‑5A, the more balanced the battery, the smaller the current. 2. SLEEP SWITCH WIRING: Reserve the wiring position for the sleep switch, the working current in the sleep power off mode is less than 0.1mA, and the accuracy of the balance voltage is within 5mV. 3. SLEEP PROTECTION: With undervoltage sleep protection, it will automatically stop and enter sleep mode when the voltage is below 3.0V, and the standby power consumption is less than 0.1mA. 4. GOOD PERFORMANCE: Adopting ultra low internal resistance MOS and 2OZ copper thick PCB, ensuring stable performance and high efficiency of the lithium battery equalizer board. 5. APPLICABLE BATTERY: The battery equalizer board is suitable for ternary lithium, lithium iron phosphate, lithium titanate battery, etc., recommended for battery with a capacity of 60‑300AH. Specification: Item Type: Battery Equalizer Board Model: EK C4S5A Material: PCB Working Voltage: 1.8V-4.5V Applicable Battery: Suitable for ternary lithium battery, lithium iron phosphate, Lithium titanate, Li ion, LTO NCM, LFP Current: 5A Battery Board Size: Approx. 66 x 46 x 16mm / 2.6 x 1.8 x 0.6in.
