3S 20A Li-ion BMS Protection Board for 18650 Batteries 12.6V PCB Charging Module for LiPo Cells with Overload Protection for Drilling Motor
This BMS (Battery Management System) protection board is designed for 3S Li-ion and LiPo 18650 batteries operating at a voltage of 12.6 V. The module provides reliable protection against overcharging, overload, and short circuits, thereby ensuring a longer lifespan for the batteries and their safe usage. It is suitable for use in drilling motors, cordless tools, and other projects requiring stable power supply.
Thanks to its compact size of 59 × 20 × 3.4 mm and a lightweight of just 4.3 g, it is easy to install into battery packs. The board is designed for continuous discharge current of up to 20 A and charge current of up to 10 A, allowing reliable use even under higher loads. In environments with poor heat dissipation, it is recommended to reduce the current to maintain safety and stability.
- Designed for 3S Li-ion and LiPo 18650 batteries – compatibility with 12.6V systems
- Maximum continuous discharge current of 20 A – suitable for more demanding applications
- Continuous charge current of 10 A – stable charging and long lifespan of cells
- Protection against overcharging, overload, and short circuits – safe use of batteries
- Compact dimensions of 59 × 20 × 3.4 mm and weight of 4.3 g – easy installation
- Package contents: 1× BMS protection board 3S 20A for 18650 batteries
This BMS module is a key component for the proper functioning and protection of lithium batteries.
