18 kWh you
build yourself.
The GP-SR1-JK-KIT-18K is a DIY battery kit with a 200A JK BMS, active balancing, and WIFI monitoring — everything you need to build a 51.2V LiFePO4 battery, except the cells. Supply your own 356Ah cells and assemble it yourself.
The kit.
Not the cells.
The kit brings the 200A JK BMS, WIFI monitoring module, enclosure, and assembly hardware. You supply the LiFePO4 cells — choose your own, and keep the savings from building it yourself.
- 200A JK BMS and 2A active balancer included
- WIFI monitoring module included
- Rack enclosure and assembly hardware included
- LiFePO4 cells sold separately (356Ah, 16S1P recommended)
- Builds a 18.227 kWh / 51.2V system once cells are added
A JK BMS that
watches every cell.
The 200A JK BMS monitors voltage, current, and temperature in real time, while a 2A active balancer keeps every cell in step — so the pack you build stays balanced from day one.
- 200A JK BMS with real-time monitoring
- 2A active balancer keeps cells matched
- Overcharge, over-discharge, and short-circuit protection
- Structural and electrical safety
Watch it
from anywhere.
The included WIFI module connects your battery to an app, so you can check state of charge, voltage, and cell balance from your phone — Bluetooth is there too for close-range access.
- WIFI monitoring module included
- Bluetooth for close-range access
- RS485 / RS232 / CAN for inverter communication
- Real-time status from your phone
Start with one.
Grow to 274 kWh.
Once built with 356Ah cells, each module delivers 18.227 kWh. Parallel up to 15 modules for 274 kWh and 150 kW of continuous power.
- Parallel up to 15 modules — 274 kWh total
- 200A / 10 kW continuous per module, up to 3000A / 150 kW
- Floor or rack-mount installation
- 884.69 × 482.8 × 240 mm complete module footprint
Built for every
way you use it.
From home energy storage and solar self-consumption to off-grid independence and installer projects, the GP-SR1-JK-KIT-18K fits.
JK BMS Warranty & Important Notice
Unlike the PC200 BMS, the JK BMS firmware and software are developed and maintained entirely by JK. As the hardware integrator, we do not have access to, or control over, the JK BMS firmware or software.
If firmware or software issues are identified, we can report them to JK and request improvements or firmware updates. However, the implementation, release schedule, and effectiveness of such updates are solely determined by JK.
Therefore, Gobel Power cannot be held responsible for any issues caused by the JK BMS firmware or software. Our warranty covers JK BMS hardware only and does not extend to firmware or software behavior.
Important Notice
- SOC (State of Charge) accuracy may not always be reliable.
- When multiple battery packs are connected in parallel, it is common for different packs to display noticeably different SOC values, even when their voltages are nearly identical.
- The JK BMS does not currently support manual SOC calibration or synchronization between parallel battery packs.
- These behaviors are limitations of the JK BMS firmware and software rather than the battery hardware.
Power you build.
Savings you keep.
Backup power, solar self-consumption, or full off-grid independence — the GP-SR1-JK-KIT-18K gives you the JK BMS, WIFI monitoring, and everything else you need to build a dependable LiFePO4 energy storage system, backed by Gobel Power's warranty.

This DIY battery box kit includes everything you need except the LiFePO4 cells:
- 200A JK BMS (V19) with a built-in 2A active balancer for real-time voltage, current, and temperature monitoring
- WiFi monitoring module plus Bluetooth for close-range app access
- Heavy-duty steel battery case (server-rack / floor-standing enclosure)
- Integrated DC circuit breaker, high-insulation epoxy boards, and thick flexible copper busbars
- LCD touchscreen display, power switch, collection wiring harness, communication board, and full mounting hardware
LiFePO4 cells are NOT included and must be purchased separately. The box is custom-fit for 16x EVE 356Ah cells in a 16S1P arrangement, which builds an 18.227 kWh / 51.2V system. Sourcing your own cells keeps the savings from building it yourself.
The JK 200A BMS supports multi-protocol CAN / RS485 / RS232 communication, so it integrates with mainstream hybrid solar inverters in lithium battery mode (e.g. Deye, GoodWe, Growatt, Victron, Solis, Luxpower and more).
No BMS communication input on your inverter? No problem — just set the inverter manually in lead-acid mode:
- Max charge voltage:
55.2V(3.45V per cell) - Max charge current:
150A - Max discharge current:
200A
The BMS continuously provides overcharge, over-discharge, and short-circuit protection either way.
Yes. The included WiFi module connects the battery to the mobile app / Gobel VRM platform, so you can check state of charge (SOC), voltage, current, and cell balance remotely from your phone — anywhere, any time.
- Bluetooth is also built in for close-range access via the mobile app
- RS485 / RS232 / CAN ports feed real-time battery status to your inverter or energy dashboard
- The 2A active balancer keeps every cell matched cycle after cycle, so the readings stay meaningful
No extra display wiring or DC-DC converter is needed — everything ships in the kit.
Yes. Once built with EVE 356Ah cells, each module delivers 18.227 kWh / 51.2V with 200A (10 kW) continuous output.
- Parallel up to 15 modules for a total of 274 kWh and up to 3000A / 150 kW combined
- Floor-standing or standard server-rack installation (884.69 × 482.8 × 240 mm footprint)
Parallel guidelines:
- Only parallel packs of the same capacity and same cell version — never mix 15 kWh and 18 kWh packs or different cell models
- The JK BMS does not support manual SOC calibration/synchronization between parallel packs, so SOC readings may differ slightly between packs even at identical voltage. Perform a full charge to 100% at least once a month to keep SOC accurate
If you want stronger SOC and firmware support for parallel systems, consider the PC200 BMS version of this kit.
Warranty:
- The JK BMS hardware is covered under warranty. Please note the JK BMS firmware and software are developed and maintained entirely by JK — as the hardware integrator, Gobel Power cannot be held responsible for firmware or software behavior (e.g. SOC display quirks), though we will report issues to JK and request fixes
- LiFePO4 cells purchased with the kit carry a 10-year warranty; the kit is otherwise backed by a 5–10 year warranty with comprehensive after-sales support
- Prefer full firmware support? Choose the PC200 BMS version, which comes with its own display
Delivery & returns:
- Ships from the China warehouse in 50–60 days
- 30 days free return to the local warehouse
