Feature: 1. This battery active equalizer suite for ternary lithium battery, lithium iron phosphate battery, and LTO battery. 2. Using ultra low internal resistance MOS and premium Printed Circuit Board, ensuring excellent balance effect. 3. The working voltage is 1.8V to 4.2V, and when it's lower than 3.0V, it will automatically stop and enter dormant state. 4. The balance accuracy is 5MV, the sleep current is less than 0.1mA, and the efficiency is very high. 5. No external power supply is required, and the transfer is carried out by means of the internal energy transfer of the battery and the balance of the entire battery pack. Specification: Item Type: Battery Active Equalizer Material: Printed Circuit Board Function: Suitable for NCM battery, LFP battery, LTO battery.
