PGY106 12V 5A 4S
Product Detail
Product Overview
The PGY106 is a compact battery protection board designed for 4-series (4S) LiFePO₄ battery packs.
It supports up to 5A continuous charge and discharge current and adopts a common port design, allowing charging and discharging through the same terminals.
This hardware-based BMS provides essential battery safety functions, including overcharge, over-discharge, over-current, and short-circuit protection, making it ideal for small LiFePO₄ energy storage modules, backup power systems, and DIY battery assemblies.
