Product descriptions: LVNOON 5.5A 3S to 21S 4S 5S 6S 7S 8S 9S 10S 12S 14S 16S 17S 20S 21S Smart Active Balancer Active Equalizer Balancer for li-ion NCM Lifepo4 LFP LTO Battery Energy Capacitor

Cascading Capability: equalizers support cascading, enabling users to expand their battery management system

This smart active balancer is a capacitive energy transfer balancer that can provide continuous all-round balance for 24 hours. Using capacitive transfer technology, no external power supply is required, and the whole group balance is achieved by internal energy transfer of the battery, with extremely low loss.

Main features: 5.5A smart active balancer; high balancing efficiency; balanced energy transmission, low energy consumption, less heat generation, high safety, and long-term protection of the battery, prolong battery lifespan, reduce maintenance fees, save money.

Important note : This item needs to be soldered a few wires, please make sure you can do this job or solder it by a professional installer if you don’t have any relevant installation experience. <br> Before connecting the balance wire to the balance board, please check whether all the wiring connections are all connected properly, and the bottom plate and the battery connection terminals must be insulated to prevent short circuit and burning.
