Mini 1S Li-Ion Battery Power Module with LED Display

Q: What type of batteries is this 1S power module compatible with?

This module is designed for 1S 3.7V–4.2V Li-Ion and Li-Po batteries. It accurately monitors battery voltage across four detection points, providing clear LED charging and discharging indication for your lithium battery projects.

Q: How difficult is it to install the 1S battery power module?

Installation is straightforward — only two wires need to be soldered (positive B+ and negative B− terminals). No additional configuration or settings are required, making it ideal for hobbyists, makers, and electronics enthusiasts of any experience level.

Q: Will this module drain my battery when not in active use?

No. The module features an ultra-low current consumption of less than 10µA in standby, which means it has virtually no impact on your battery's overall capacity or runtime.
