22V 20A Charge Protection Board Li-ion Lithium Battery 24V 18650 Charger Protection Board Module is a small PCB mount Li-ion Lithium Battery charger protection module. This small battery charger protection module comes with various features like Short circuit protection, Overcharge protection, Over-discharge protection, Overcurrent protection. It is very easy to install and convenient to use in all your DIY portable projects.
Description:
The main 22V 20A Charge Protection Board 18650 Charger (lithium-ion Battery Management System). A charge controller, charge regulator, or battery regulator limits the rate at which electric current is added to or drawn from electric batteries. It prevents overcharging and may protect against overvoltage, which can reduce battery performance or lifespan and may pose a safety risk.
The protection board can be used as a four-component polymer lithium battery pack with a nominal voltage of 14.4V, 14.8V, 16.8V, and four series of 18650 lithium batteries for overcharge and over-discharge, short circuit protection.
Specification :
- Overcurrent detection voltage: 150mV
- Overcurrent detection delay: 9MS
- The Overcurrent protection current: 30 ± 3A
- Overcharge detection voltage: 4.28 ± 0.05V
- Overcharge protection delay: 0.1S
