Battery protection board
Battery protection board, as the name suggests lithium battery protection board is mainly for the rechargeable (generally refers to lithium battery) to protect the integrated circuit board. Lithium-ion batteries (rechargeable) need protection because of their own characteristics. Because the material of the lithium battery itself determines that it can not be overcharged, overdischarged, overcurrent, short circuit and ultra-high temperature charging and discharging, so the lithium battery lithium module will always follow a protection plate with sampling resistance and a current insurance device.
