Gobel Power PC200B 51.2V LiFePO4 Battery Case DIY Kit

The PC200B BMS is included in this kit: a smart 16S inverter BMS with:

• Built-in 2A active balancer keeping every cell matched cycle after cycle
• Real-time monitoring of voltage, current, and temperature
• An LCD touchscreen display on the BMS itself
• No Bluetooth on the BMS — remote access is via the optional WiFi module instead

This is exactly why many buyers pick the PC200B over the JK BMS: PC200 firmware and software are maintained by Gobel Power, so you get full firmware-related after-sales support — no JK-style firmware disclaimers.

Optional accessories: heating pad (+¥68.30) for cold-climate charging and a 250A bolt-fuse (DC150V, 20kA breaking capacity) for extra short-circuit protection.

Yes. The PC200B connects to the Gobel VRM online monitoring platform, so you can monitor and manage your battery anytime, anywhere:

• Online monitoring and management of multiple packs with the plug-and-play RS232-WIFI module (PWA1) — bought separately
• Android APP available from the Google Play Store; a web dashboard is at vrm.gobelpower.com (a demo account is provided on the product page so you can try the platform before buying)
• A WiFi module user manual is included in the related downloads

Closer to the pack, the BMS LCD touchscreen shows voltage, current, and cell status directly. CAN/RS485 ports feed battery data to your inverter.

The PC200B BMS supports CAN and RS485 communication, so the finished 51.2V battery integrates with mainstream hybrid solar inverters in lithium battery mode (Deye, GoodWe, Growatt, Victron, Solis, Luxpower and more).

Inverter without a BMS/lithium communication input? Configure it manually in lead-acid mode:

• Max charge voltage: 55.2V (3.45V per cell)
• Max charge current: 150A
• Max discharge current: 200A

The BMS keeps providing overcharge, over-discharge, and short-circuit protection either way. For multi-pack systems, parallel only the same capacity and cell version, and do a full charge to 100% at least monthly to keep SOC accurate.

Safety features:

• Integrated 200A circuit breaker (2P100A) for overload and short-circuit protection
• Optional 250A bolt-fuse (rated DC150V, 20kA breaking capacity)
• Epoxy sheets, fuse protection, heavy flexible copper busbars, and full mounting hardware
• Optional heating pad for safe low-temperature charging

Warranty:

• Cells purchased for the kit carry a 10-year warranty; the BMS carries a 1-year warranty (hardware only)
• 30 days free return to the local warehouse

Delivery:

• Ships from the China warehouse in 50–60 days; spare parts ship faster via UPS/DHL
• Sea freight with tax already paid — free tax to your door
