XINTechPro 16S 48 V 200 A JK BMS Pre-Wired DIY Box for 280–320 Ah LiFePO₄ Cells

Unlock pro-level battery protection in minutes — no soldering, no wiring guesswork. Our XINTechPro Pre-Wired BMS Box comes with a 200 A JK BMS already installed and connected, so you can go from unboxing to a fully protected 48V LiFePO₄ battery system with minimal effort. Designed for high-capacity builds, this DIY box is optimized for 16-series (16S) LiFePO₄ cells, especially 280 Ah, 304 Ah, 314 Ah, and 320 Ah variants. Whether you're building a solar energy bank, RV/van power system, or backup power cabinet, it's engineered to give you high performance, long life, and built-in safety. With real-time Bluetooth monitoring, you can keep an eye on cell voltages, temperature, current, and balance status via the JK BMS mobile app. Plus, the 200 A continuous rating supports heavy loads while delivering robust protection: overcharge, over-discharge, over-current, short-circuit, and temperature. This is more than just a BMS — it's a plug-and-play, pro-grade energy solution. Specification D
