The 1S 15A BMS Protection Board is designed to provide essential protection for single-series (1S) 3.7V lithium-ion and lithium-polymer battery systems. It can be used with 18650 cells, Li-Po batteries and other compatible single-cell lithium battery configurations.

The board uses multiple 8205A MOSFETs and provides protection against common battery-related electrical faults, including overcharging, over-discharging, excessive current and short circuits. This helps protect both the battery and connected electronics during normal charging and discharging.

The board provides dedicated battery and power connection points. B+ and B− are used for the battery connection, while P+ and P− are used for the charging/load connection. Correct polarity must be maintained during installation.

Its slim and compact design makes it suitable for custom 18650 battery packs, power banks, rechargeable electronics, DIY UPS projects, portable devices and other 1S lithium battery applications where a protection circuit is required.

Important: This BMS is designed for 1S lithium-ion/Li-Po batteries only. It is a battery protection board and does not function as a standalone battery charger.
