POWER Bảng Mạch Bảo Vệ Pin Sạc 18650 Lithium 3s 10.8v / 12.6v

Giới thiệu POWER Bảng Mạch Bảo Vệ Pin Sạc 18650 Lithium 3s 10.8v / 12.6v

This protection board uses a mature 3S dedicated lithium battery protection chip for central control
It has the characteristics of high integration and high sensitivity
Real-time protection of battery overcharge, overdischarge, discharge overcurrent, short circuit, charge overcurrent, etc., by detecting the charge and discharge current and voltage of each battery
The adjustment of the parameters can also be achieved through an external circuit.
The design of the protection board is mature and the quality is excellent
Guangfan is applied to the battery pack that uses 3 18650 lithium battery electric drills, it is your reliable product!
