12V 25A 3S 18650 Lithium Battery Protection Board BMS Module

Overview of this 12V 25A 3S 18650 Lithium Battery Protection Board BMS

Introducing the Roboway 12V 25A 3S 18650 Lithium Battery Protection Board BMS Module at the best price in India with Roboway. This board is specially made for 3S (3 cells in series) 18650 lithium-ion batteries, which usually give a nominal voltage of around 11.1V and full charge voltage of 12.6V. It can safely handle up to 25 amps of continuous current for making it suitable for medium-power applications like DIY power banks, e-bikes, LED lights, solar storage, and small inverters.

The 12V 25A 3S 18650 Lithium Battery Protection Board automatically stops charging when any cell reaches its safe limit (around 4.2V), preventing battery damage and extending battery life also the board instantly disconnects in case of short circuit or if the current goes beyond its safety limit, ensuring both the battery and connected devices remain safe.
