Product Technical Information
Technical Details
The 3S 25A Balance 18650 Lithium Battery BMS is designed to manage and protect battery packs made from three Li-ion cells connected in series. A 3S configuration has a nominal voltage of approximately 11.1V when using 3.7V nominal cells and reaches approximately 12.6V when fully charged.
The integrated balancing function helps manage voltage differences between the three series-connected cells during charging. This is particularly useful for maintaining a more consistent cell voltage across the battery pack.
The BMS also provides protection against overcharge, over-discharge, overcurrent, and short-circuit conditions according to its intended protection functions. With a stated 25A current rating, it can be used in appropriately designed higher-current battery applications.
