Specification: Item Type: Active Equalizer Material: PCB, copper Purpose: Inductive energy transfer balance board, high current 1.2A energy transfer battery voltage balancer, significantly balance the battery voltage, improve the overall efficiency of the battery pack Working Voltage: 2.0V-4.5V, universal for ternary lithium iron battery, not applicable for LTO lithium titanate battery Balance Current: The adjacent voltage difference is above 0.1V (current is about 0.5-0.7A); The adjacent voltage difference is above 0.2V (reaching an equilibrium current of 1.2A); The smaller the voltage difference, the smaller the equalizing current Wire Length: Approx. 30cm / 11.8in (pure copper 22AWG terminal wire) Package List: 1 x Balance Module 1 x Connection Line Note: This board is based on the principle of adjacent equalization and cannot be used as a maintenance tool. To connect the battery, it must be used with lithium battery protection. The voltage difference generated by charging and discharging triggers the work of the equalization board to achieve energy transfer balance. Package List 1 x Balance Module 1 x Connection Line
