Type C BMS 4S 2A 18650 Lithium Battery Charger Board for Li-Po Polymer Power Bank

Type-C Charging Port – The board comes with a Type-C input, which is widely used and provides fast, reliable, and easy charging compared to older USB ports.

Supports 4S Battery Pack – It is designed for 4-cell (4S) 18650 lithium-ion or Li-Po batteries, making it perfect for medium-power applications like power banks and DIY battery packs.

Balanced Charging – The board balances each cell while charging, which helps improve battery life, ensures equal charging, and prevents one cell from overcharging.

2A Charging Current – It can supports up to 2A charging current, which gives a good balance of safe charging speed and efficiency without overheating the battery pack.

Overcharge Protection – It automatically stops charging once the battery reaches full voltage, preventing damage and extending battery lifespan.
