The SERVTEC USB Diagnostic Cable provides comprehensive diagnostic access to Pylontech US2000, US3000, and US5000 series batteries via the console port. Designed for professionals and advanced users, this cable enables in-depth monitoring of battery health, cell voltages, cycle counts, and more.

Compatible Models

This cable is fully compatible with the following battery models:
US2000, US2000+, US2000B, US2000C, US3000, US3000+, US3000B, US3000C & US5000

Both cables included to ensure compatibility with later C-series and US5000 models.

Key Features

✔ Comprehensive Diagnostics – Monitor cell voltages, cycle counts, balance status, and overall battery health.
✔ Real-Time Monitoring – Works with Battery View Software, ICC, MultiSIBControl, PVOutput, and EmonCMS.
✔ Plug-and-Play – Includes drivers for Windows 98SE to Windows 11. Also supports Raspberry Pi (via Minicom or similar terminal applications).
✔ Advanced Handshake Protocol – Automatically detects and reports BMS software revision for precise compatibility.
✔ Status Indicators – Built-in RX/TX LED indicators allow real-time monitoring of data transmission.
✔ Multi-Battery Support – If your batteries are linked via short black communication cables, the diagnostic cable connects to the master unit, allowing you to access data from all connected modules.

Monitor Critical Battery Data

Using this cable, you can access vital information, including:
🔹 Battery Module State of Health (SOH) – Check individual module health, not just overall bank SOH.
🔹 Battery Cell Voltage & Balance – Ensure cells are properly balanced for optimal performance.
🔹 Battery Temperature Monitoring – Track individual cell temperatures to prevent overheating or inefficiencies.
🔹 Charge & Cycle History – Analyze historical data, including cycle count, charge count, discharge count, and over/under voltage events—ideal for assessing used batteries before adding them to a system.
🔹 BMS Firmware Version – Ensure the latest BMS revision is set as the master when expanding your battery bank.
🔹 System Health Data – View remaining capacity, fully charged capacity, SOH, and SOC—useful for warranty claims and long-term maintenance.
