Description
🧾 Product Description:
The JBD BMS LFP 4S 120A (Model ZP04S014) is a high‑capacity, hardware Battery Management System (BMS) designed specifically for 4‑cell in series (4S) lithium‑iron‑phosphate (LiFePO₄ / LFP) battery packs—nominally around 12.8 V.
This BMS supports an impressive continuous discharge current of up to 120 A, making it ideal for high‑current applications such as electric vehicles (12 V class), solar energy storage systems, high‑load UPS or backup systems, power tools or robust DIY battery packs.
It features comprehensive protection functions including over‑charge, over‑discharge, over‑current, short‑circuit, and temperature protection. It also incorporates cell balancing (≈ 250 mA) and a low internal resistance (≤10 mΩ) for efficiency and durability.
