    Note

    Unlike the PC200 BMS, we do not have control over the JK BMS firmware and software. If there are bugs in the JK BMS firmware or software, we can report them to JK and request a upgrade, but this is not always effective. Therefore, we cannot be held responsible for any issues caused by the JK BMS firmware or software. Our warranty is limited to the JK BMS hardware only.

    Note:

    1. The parts in the kit are designed for single-pole cells and dual hole cells.

    2. This kit cannot be used with over-over-swollen cells. We recommend using cells from Gobel Power.

    3. Internal cable size: Positive (ultra soft 10000 cores 50mm2 cable), Negative (ultra soft 5000 cores 2*25mm2 cable)

    Why Choose Gobel Power DIY Kit

    Gobel Power 16S 51.2V 280Ah 314Ah LiFePO4 Battery DIY Kit Box
    Durable Box
  • With Internal Frames
  • Enhances the Rigidity
  • Protect Cells
  • Gobel Power 16S 51.2V 280Ah 314Ah LiFePO4 Battery DIY Kit Box
    Long Life Cycle
  • Compress Plate
  • Thickness: 3mm
  • Increase Life Cycles
  • Without a compression plate, the cells cannot be compressed, which will shorten their lifespan. Additionally, if the cells expand before assembly, it will be difficult to assemble them.
    Gobel Power 16S 51.2V 280Ah 314Ah LiFePO4 Battery DIY Kit Box
    BMS Safety
  • Separate BMS Plate
  • Protect BMS
  • Easy Installation
  • If the BMS is fixed to the compression plate, cell expansion after several years of use may cause the compression plate to deform, potentially leading to BMS deformation and damage. A standalone BMS plate can prevent this issue.

    Frequently Asked Questions

    What is included in the EU Stock 51.2V 16S JK BMS battery DIY kit case, and which LiFePO4 cells fit?

    The GP-SR1-Kit is a complete 16S build package for a 48V/51.2V LiFePO4 battery — everything except the cells:

    • Battery case — durable server-rack style enclosure (White)
    • JK 16S 200A BMS (JKBMS V19) with built-in 2A active balancer, Bluetooth monitoring, and CAN/RS485 communication
    • LCD display screen, power switch, collection wiring harness, and communication board
    • 200A circuit breaker (2P100A) for overcurrent and short-circuit protection
    • Copper busbars, terminals, cables, epoxy sheets, and mounting screws

    LiFePO4 cells are NOT included — purchase separately. The case and busbars fit EVE MB31 280Ah / 304Ah / 314Ah cells (also EVE 306Ah and various brands of 280Ah-class cells). Do not mix different capacities or cell versions in one pack (e.g. 280Ah V1 with V3 or 314Ah) — mismatched cells shorten pack lifespan and create safety risks.

    Optional accessories: heating pad (2A/120W) for cold-climate charging and an external active balancer (4A/5A/10A) for higher balancing current.

    Is the JK BMS Bluetooth or WiFi, is the 2A balancing start voltage configurable, and are JK screens compatible with it?

    Connectivity: the JK BMS ships with Bluetooth for close-range monitoring via the mobile app — it has no built-in WiFi. For remote online monitoring, add the optional WIFI module (bought separately), which connects the battery to the Gobel VRM platform.

    2A balancing threshold: Yes, it is configurable. In the BMS host software or mobile app you can set the balancing start voltage — the 2A active balancer stays on standby until any individual cell reaches or exceeds your configured threshold, and automatically deactivates below it to conserve energy.

    Screens and displays: JK screens are compatible with all JK BMS models, and the display wiring harness needs no DC-DC converter — JK handles it on the harness. If you prefer a BMS with stronger firmware support, our PC200 BMS version of this kit is developed and maintained entirely by Gobel Power.

    Which solar inverters work with the JK 200A BMS, and how do I set up an inverter without a BMS communication port?

    The JK 200A BMS communicates over CAN or RS485, so the kit integrates with mainstream hybrid solar inverters (Victron, Deye, Goodwe, Growatt, Solis, Sofar Solar, etc.) in lithium battery mode.

    If your inverter has no BMS communication input, configure it manually in lead-acid mode — no communication is required:

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

    The BMS provides real-time cell voltage, current, and temperature monitoring plus overcharge, over-discharge, and short-circuit protection in either mode, and the Bluetooth app lets you track the pack at a glance.

    How fast does the EU stock kit ship, and what is the warranty for the cells and JK BMS?

    Shipping: this kit ships from EU stock in Germany — estimated 7–15 day delivery with free tax (VAT prepaid; no extra customs costs on delivery). Spare parts ship by UPS/DHL. 30 days free return to the local warehouse. Note: our EU freight forwarder does not issue VAT invoices, but you will not pay additional taxes.

    Warranty:

    • LiFePO4 cells: 10-year warranty on DIY kit cells
    • JK BMS: 1-year warranty covering hardware only — the JK firmware and software are developed and maintained entirely by JK, so Gobel Power cannot be held responsible for JK firmware/software behavior

    JK firmware notes (not hardware defects): SOC accuracy may vary between parallel battery packs, and the JK BMS does not support manual SOC calibration between packs — fully charge the pack to 100% at least once a month to keep SOC readings accurate and prevent drift. For full firmware support, choose our PC200 BMS version of this kit.
