Turmera 4S 14.4V 16.8V 30A 40A BMS 18650 Lithium Battery Protect Board Balance With DC Plug for Electric Drill Screwdriver Batteries Use

Features:

The protection board is for 4 series Li-ion batteries, mainly used for electric power tools.

It uses special IC for 4S lithium batteries as processor to detect real-time voltage, charge and discharge current and ambient temperature of each battery.

Stable various protective functions for charging and discharging, such as overcharge protection, over-discharge protection and short circuit protection.

Low power consumption,the working current is about 25uA and quiescent current is about 6uA.

Choosing the correct protection board and applying it appropriately is vital to the longevity your batteries.
