3S 4S 5S 6S 7S 8S 10S 12S 14S 16S 17S 21S 5A Capacitive Active Equalizer Balancer LFP Lifepo4 Lithium Ion/Lithium Titanate LTO Battery Energy Transfer Active Equalizer (EK-21S5A)

Capacitive active equalization board serves as the core component of the next-generation battery management system. It is designed for lithium battery packs and supercapacitor modules, achieving efficient voltage equalization between battery cells via capacitive energy storage and transfer technology. The working voltage is 1.8V - 4.5V, featuring a balance voltage accuracy within 5MV and high efficiency. The balance current ranges from 0-5.5A, where a smaller balance results in a smaller current. The sleep mode current is under 0.1mA. The quiescent current is approximately 12mA. Batteries in the 30-300AH range are recommended. This board is suitable for high-energy-density applications like electric vehicles, energy storage power stations, and drones, where it enhances battery pack performance and safety. Package includes: Equalizer *1, terminal cable *1.
