Review on Anmbest Balancer 4S 16.8V 30A 18650 Charger - Efficient Lithium Battery Protection Board for Li-ion & Lipo Cells by Rosemary Wright

Revainrating 3 out of 5

Working but not on 15A

Overview refers to 6S board. Is working. It limits the high and low voltage for each individual cell. But it heats up at 3A and gets very hot at 8A. It will not work in a battery pack (cells wrapped around it). I tested it at 10A discharge and 5A charge but it requires a heatsink. 10A is ok for my application but with a 60x50x15 heatsink. 15A will likely require a larger heatsink or fan.
