2Cell String Lithium Battery Protection is a lithium battery protection board, which is based on HY2120 2-Cell Lithium-ion/Lithium Polymer Battery Packs Protection chip. This chip is designed to protect two cells of rechargeable battery charging and also to detect high-accuracy voltage and delay circuits. The HY2120 chip series can be utilized for protecting the lithium-ion and lithium-polymer battery packs against overcharge, over-discharge, short circuit, and overcurrent conditions.
This circular battery protection board has MOS transistor to control the battery charge and discharge status, and also has an internal three-step over-current sensing circuit to safe wide various types of 3.7V  lithium-Ion batteries. The HX-2S-A2 module can accurately detect the battery voltage to control it. This module is a small, high performance, and low cost, that makes it a good solution for a wide range of battery protection requirement.
