Specification: Certification: NONE Origin: Mainland China Accessory Type: Battery Accessories Lithium battery active equalizer energy transfer board 2-17 series inductance transduction 1.2A high current equalization module Specifications: 2/3/4/5/6/7/8/9/10/12/13/14/16 strings (optional) Product parameters: The working voltage is 2.0V-4.5V, ternary lithium iron battery is universal, LTO lithium titanate battery is not applicable. Balance current: The adjacent voltage difference is more than 0.1V (the current is about 0.5-0.7A); The adjacent voltage difference is above 0.2V (reaching the maximum balanced current of 1.2A); The smaller the voltage difference, the smaller the equalizing current. Product Size: 25*22*7mm (2 strings) 40*22*7mm (3 strings) 55*23*7mm (4 strings) 45*45*7mm (5 strings) 55*45*7mm (6 strings) 55*45*7mm (7 strings) 70*45*7mm (8 strings) 70*45*7mm (9 strings) 85*45*7mm (10 strings) 100*45*7mm (12 strings) 100*45*7mm (13 strings) 110*45*7mm (14 strings) 105*45*7mm (16 strings) Precautions: 1. This board works on the principle of adjacent equalization and cannot be used as a maintenance tool. It must be used together with lithium battery protection to connect to the battery. The pressure difference generated by charging and discharging triggers the equalization board to work to achieve energy transfer balance. 2. Inductive energy transfer equalization board, high current 1.2A energy transfer battery voltage balancer, can significantly balance the battery voltage and improve the overall efficiency of the battery pack. Wiring definition: B-, the total negative pole of the battery pack (the negative pole of the first battery) B1, the positive terminal of the first battery B2, the positive terminal of the second battery B3.......and so on. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
