4S 30A 16.8V BMS for Lithium-Ion Battery with Balance Charging

This product is a 4 series 3.7v lithium battery protection board. Large current protection board, 30A direct current battery protection panel for the integrated circuit board which can be used for protection of rechargeable (generally known as lithium batteries). Lithium battery (rechargeable) Must be protected by its own characteristics. materials due to the lithium battery itself determine that it can not be overcharge, discharge, over current, short circuit and ultra high temperature charge and discharge, so lithium battery components always follow a sampling resistance protection board of belt and a piece of chain protection device

The Scope of Nominal voltage of 3.7V lithium battery (including 18650,26650, a polymer lithium battery) where Charging voltage can be range between 16.8V to 18.1V The board operates smoothly with Continuous charge current of (upper limit): 20A.
