Overview

Product Overview

HX-2S-JH20 2S 7.4V lithium battery protection board is a compact 18650 battery BMS designed to manage and protect 2-cell packs during charge and discharge, making it ideal for DIY battery packs, portable electronics, robotics, and power-bank style projects. Rated for 10A output, it helps safeguard lithium cells in multi-cell use while the built-in balancer works to keep both series cells aligned for more stable pack performance and improved battery life. It is well suited to custom rechargeable devices, LED lighting packs, small backup power builds, and other 2S battery applications where reliable pack protection and cell balancing are essential.

Questions & answers

Frequently asked questions

Yes. This protection board is designed for 2-cell series lithium battery packs, including 2S 18650 packs with a 7.4V nominal voltage. It is not intended for single-cell or higher-series battery configurations.
This ShillehTek version is supplied pre-soldered to reduce assembly work, but the battery, charger, and load still must be wired correctly. Follow the board markings and use proper lithium battery safety practices during installation.
The board is made for 2S lithium packs with a 7.4V nominal pack voltage and is rated for 10A output. It provides pack protection during charge and discharge and includes balancing for the two series cells.
Yes, it can be used in small robotics builds that need a rechargeable 2S lithium pack, as long as the robot electronics are compatible with 7.4V nominal input and the load stays within the board’s 10A rating.
The built-in balancer helps keep the two series cells aligned, but starting with similar, healthy 18650 cells is still important. Avoid mixing damaged, unknown, or very different cells in the same pack.
