2S 8A BMS Protection Circuit Board for 18650 Lithium-Ion Batteries (Model: HX-2S-JH10)
This 2S 8A Battery Management System (BMS) is a compact yet powerful protection board designed to manage and safeguard 7.4V (2S) lithium-ion battery packs, such as 18650 cells. It intelligently regulates the charging and discharging process while providing critical protection to extend battery life and prevent damage.
🔧 Key Features:
-
High-precision voltage detection for reliable performance.
-
Designed for 2-series (2S) lithium-ion batteries (7.4V nominal).
-
Integrated three-stage overcurrent protection: overcurrent 1, overcurrent 2, and short-circuit protection.
-
MOSFET-based switching enables efficient charge/discharge control.
-
Low quiescent current helps preserve battery life during standby.
