12V EVE MB56 628Ah LiFePO4 Battery Kit 8.04kWh with JK BMS
12V 628Ah EVE MB56 LiFePO4 Battery Kit – Approx. 8.04kWh
Build a serious high-capacity 12V battery bank using genuine matched EVE MB56 628Ah LiFePO4 cells. Choose the battery kit only, the battery kit with its purpose-fit case supplied unassembled, or the battery kit fully assembled inside the case.
Overview
The 12V EVE MB56 Battery Kit is designed for caravans, RVs, motorhomes and off-grid systems requiring substantial 12V battery capacity. It uses 4 EVE MB56 628Ah LiFePO4 cells connected in series to create a nominal 12.8V battery bank.
With approximately 8.04kWh of nominal energy storage, this kit is well suited to larger mobile power systems, off-grid sheds, tiny homes, marine applications, backup power and high-capacity 12V battery builds.
Three configurations are available, allowing you to choose the level of enclosure and assembly that best suits your project.

Which Option Should I Choose?
- Battery Kit Only: best if you already have a suitable enclosure or want complete flexibility over your battery build.
- Battery Kit + Case – Unassembled: ideal if you want the complete kit and a purpose-fit enclosure but prefer to carry out the assembly yourself.
- Battery Kit + Case – Assembled: best if you want the cells, BMS, busbars and cables installed inside the enclosure for you, reducing the assembly required before final installation.
Why Add the Battery Case?
- Cleaner installation: keeps the cells, BMS and battery hardware organised inside one enclosure.
- Purpose-fit design: sized to suit a 12V 4S EVE MB56 628Ah battery build.
- Durable construction: plastic outer case with a metal insert for added strength.
- Portable design: helps keep your battery build contained and easier to handle.
- Assembly choice: assemble the battery yourself or have the kit assembled inside the case for you.
Important Information
The Battery Kit Only option is supplied as a DIY battery kit and requires assembly, insulation, wiring, protection and configuration.
The Battery Kit + Case – Unassembled option includes the plastic outer case with metal insert and requires customer assembly.
The Battery Kit + Case – Assembled option includes the cells, BMS, busbars and supplied battery cables assembled inside the case.
Final system installation, connection, configuration and commissioning are still required for the assembled option.
Final installation should be completed by a suitably qualified person familiar with high-capacity DC battery systems.
Always use a BMS with a temperature sensor when connecting LiFePO4 cells in series to help ensure safety and long-term performance.
These are brand new genuine matched cells. Do not be fooled by cheap recycled cells. Learn about the difference between Solar Grade and Auto Grade cells.
Before working with LiFePO4 cells, please read and follow our Product Safety Disclaimer. Failure to do so may void warranty.
FAQs
