Description: Durable. Battery equalizer made of high performance material,durable. Replacement. Equalizer,nice replacement accessory for your old or broken one,. Purpose: Current 1.2A energy transfer battery voltage balancer, significantly balance the battery voltage and improve the overall efficiency of the battery pack. Working voltage:2.0V-4.5V,Equalization module common for ternary iron lithium battery, not for LTO lithium titanate battery. Balance current:The adjacent voltage difference is more than 0.1V (the current is about 0.5-0.7A;the adjacent voltage difference is more than 0.2V (to reach the equilibrium current of 1.2A) Specification: Balance Instructions: 1. When the equalization light is on, the equalization work is turned on, 2. The equalization light is off, the equalization circuit is in sleep state, 3. The equalization light flashes, indicating that the string is dropped, or the circuit is faulty. Size Chart: Material: Electronic Component Size:Approx.50x20x6.5mm/1.97x0.79x0.26inch Package Includes: 1 Piece 4 Strings Battery Equalizer
