Heltec Wholesale Active Equalizer Balancer 5A 3S-21S 4S 6S 7S 8S 14S 16S 17S 20S 21S Lifepo4/Lipo/LTO Battery Energy Capacitor

Feature

Working voltage: 1.8V-4.5V

Suitable for ternary lithium, lithium iron phosphate, lithium titanate.

Working principle, the capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB

Equilibrium current 0-5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv!

The quiescent current is about 12 mA. It is recommended that the battery capacity is 60-300AH.

With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA.

Ternary Lithium/Lifepo4 In Default,LTO need to change the welding like below

3S-4S, does not support LTO battery, only supports lithium ternary/lifepo4 batteries

Voltage Displays4S/ 6S /8S
