Features

Overcharge Protection – This board stops charging the battery once it reaches around 8.4V, so the cells do not get damaged from extra charging.

Over-discharge Protection – It cuts off the battery when voltage drops too low (around 2.8V per cell), which helps increase battery life and avoids deep discharge.

Overcurrent / Short Circuit Protection – If the current is too high or the battery wires are shorted, the board automatically disconnects to prevent overheating or damage.

Balanced Charging – Ensures that both cells in the 2S battery pack charge evenly, so one cell doesn’t get overcharged or undercharged.

High Efficiency – It designed to handle up to 3A current, making it suitable for small devices, DIY projects, and rechargeable packs.
