PRODUCT DESCRIPTION
Li-ion batteries are widely used in a range of indoor and outdoor devices due to their high charge storage capacity. They are more compact, efficient, and offer greater energy density compared to other battery types. However, they do have some limitations that require careful monitoring during both charging and discharging. Discharging a battery below a certain voltage can damage the cell and reduce its overall capacity, while overcharging can present serious risks, including potential explosions.
To prevent these issues, battery protection and charging circuits are essential. This product is a Li-ion single-cell charger and protection circuit designed to charge a single 15 Amp cell or 5 to 6 parallel-connected 2500mAh Li-ion cells. It incorporates MOSFETs to monitor the battery’s condition and protect against overcharging, over-discharging, and short circuits, ensuring safe and reliable operation.

Frequently Asked Questions
What voltage range does this protection board support?
This BMS board is designed for a single Li-ion cell with an operating range from 2.45 V (discharge cutoff) up to 4.25 V (overcharge cutoff), ensuring safe cell management.
Can I use this board with other cell types?
No, this board is specifically calibrated for 3.7 V nominal 18650 Li-ion cells. Using different chemistries or voltages may lead to improper protection and potential hazards.
How do I know if overcurrent protection has activated?
When an overcurrent event (above 7.5 A) occurs, the board will instantly disconnect output. Normal operation resumes once the load is removed and the board’s internal circuit resets.
