3S 20A 18650 Lithium Battery Protection Board (BMS)
3S 20A 18650 Li-ion battery protection board (BMS)—overcharge, over-discharge, and overcurrent protection for 3-cell Li-ion battery packs.
The 3S 20A 18650 Lithium Battery Protection Board (BMS) is designed to safeguard 3-cell (3S) 18650 Li-ion battery packs from overcharge, over-discharge, and overcurrent conditions. With a 20A continuous current rating, it ensures safe operation and extends the lifespan of your battery packs in DIY and portable electronics projects.
This BMS features short-circuit protection, overcurrent protection, and thermal safeguards, ensuring stable and safe performance. It also provides balanced charging for all three cells, maintaining uniform voltage and preventing damage to individual batteries.
Ideal for DIY power banks, electric scooters, portable devices, Arduino/ESP32 battery packs, and other battery-powered electronics, this 3S 20A BMS offers reliable protection while being compact and easy to integrate.
