3S 20A BMS 18650 Lithium Battery Protection Board 11.1V 12V 12.6V
- Description
- Reviews
The 3S 20A BMS lithium battery protection board is designed for 3-cell lithium-ion battery packs rated 11.1V to 12.6V. It provides essential protection features including overcharge, over-discharge, overcurrent, and short-circuit protection, ensuring safe and reliable battery operation.
This module includes a built-in balance function with approximately 100mA balancing current to maintain equal cell voltage and extend battery lifespan. Supporting up to 20A continuous charge and discharge current, it integrates multiple low-resistance MOSFETs for improved thermal and electrical performance. Its compact design makes it suitable for DIY battery packs using 18650, 26650, or lithium polymer cells.
Commonly used in electric drills, LED lighting systems, sprayers, small inverters, robotics, and portable power solutions, this 3S BMS board offers efficient battery management for medium-power applications.
Package Includes:
1 x 3S 20A BMS 11.1V 12.6V 18650 Lithium Battery Protection Board with Balance
