5.5A 5S to 21S 5S 6S 7S 8S 9S 10S 12S 14S 16S 17S 21S Smart Active Balancer Active Equalizer Balancer for li-ion NCM Lifepo4 LFP LTO Battery Energy Capacitor (17S-21S)

5.5A Smart Active Balancer 5mV Precision 3S-4S for Lifepo4 Lithium li-ion NCM Lithium / 5S-21S for Lifepo4 Li-ion LTO Battery Active Battery Energy Transfer Equalization Capacitor Important note: This item requires a few wires to be soldered. Please ensure you can perform this task, or have it soldered by a professional installer if you lack relevant installation experience. Before connecting the balance wire to the balance board, verify that all wiring connections are correctly made, and that the bottom plate and battery connection terminals are insulated to prevent short circuits and burning.
Main features: 5.5A smart active balancer; high balancing efficiency; balanced energy transfer, low energy consumption, reduced heat generation, high safety, and long-term protection of the battery, extending battery lifespan, lowering maintenance costs, and saving money. This smart active balancer is a capacitive energy transfer balancer that delivers continuous all-round balancing 24 hours a day. Using capacitive transfer technology, no external power supply is needed; whole-group balance is achieved through internal energy transfer of the battery, with extremely low loss.
Cascading Capability: equalizers support cascading, enabling users to expand their battery management system
