BMS 3S (12.6V -20A ) Lithium Battery Protection Module

BMS 3S (12.6V -20A ) Lithium Battery Protection Module is a high-quality electronic component designed for Arduino, prototyping, and educational electronics.

Features:

Module name: 3S 12.6V Li-ion Lithium Battery 18650 Charger Protection PCB Board
Suitable range: For nominal voltage 3.6V 3.7V lithium battery(Including 18650,26650, lithium polymer batteries)
Product Size: 64mmx20mmx3.4mm
Material:Metal
Charging voltage: 12.6V
Maximum output current: 20A
Maximum output power / charging power: 252W

Precautions:

1.Strictly according to the diagram wiring: 0V/4.2V/8.4V/12.6V,Otherwise it will cause damage to the chip.
2.After connection,it need to first charge activation, then will have the output.

Attention:

Do not mix the good battery and poor battery to use.
The internal resistance of 3 battery capacity are closer will be better.

It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
