Before ordering, confirm your inverter brand and exact model, communication protocol, installation space, delivery ZIP code and whether you need Texas pickup or inland USA delivery.
What Is the MB56 DIY Battery Box Designed For?
The Docan MB56 DIY box provides a mobile metal enclosure for building a high-capacity 16S, 51.2V nominal LiFePO4 battery. The internal cell compartment is designed for 16 EVE MB56 / LF628 cells arranged on one level in two rows.
- 16S, 51.2V nominal, 48V-class DIY LiFePO4 projects
- Approximately 32.15kWh nominal energy after 16 compatible 628Ah cells are installed
- Home solar storage, backup power, off-grid workshops, farms and stationary ESS projects
- Texas warehouse pickup or eligible inland USA delivery
This is a component kit, not a finished battery. Cell matching, insulation, terminal torque, inverter settings, protection design and final commissioning remain the installer's responsibility.

Can Multiple Completed MB56 Batteries Be Connected in Parallel?
Up to 15 completed battery packs may be connected in parallel only when the packs use matched cells, compatible BMS firmware and settings, coordinated communication, equal-length correctly sized cables, suitable busbars and overcurrent protection, and a system design suitable for the total current. Do not mix unmatched batteries or assume that physical connection alone makes the system ready to operate.

Assembly and Safety Planning
- Use matched cells with a consistent state of charge before series connection.
- Confirm cell orientation, polarity, insulation and connection-board alignment before tightening.
- Use the cell manufacturer's specified terminal torque; do not rely on a generic torque value.
- Keep insulated barriers in place and protect tools from accidental short circuits.
- Configure charge, discharge and temperature limits for the actual cells used.
- Have a qualified installer review grounding, cable sizing, overcurrent protection and inverter settings before commissioning.
The completed battery will be very heavy after all cells are installed. Confirm the final installation position and floor capacity before assembly.
Frequently Asked Questions
Are EVE MB56 cells included?
No. This listing is for the MB56 enclosure kit and its included control and connection components. Sixteen compatible EVE MB56 / LF628 cells must be purchased separately.
What battery can be built with this enclosure?
With 16 compatible 3.2V 628Ah cells connected in series, it can form a nominal 51.2V 628Ah system with approximately 32.15kWh of nominal energy.
How are the cells arranged?
The cell compartment is designed as one level with 16 cells arranged in two rows.
Which BMS and display are preinstalled?
The current USA-stock configuration includes a preinstalled JK PB2A16S20P V19 200A BMS with 2A active balancing and a 4.3-inch touchscreen.
Which communication interfaces are available?
The current configuration provides CAN, RS485, RS232 and Bluetooth. Inverter communication still depends on the exact inverter model, protocol, firmware and cable pinout.
Does the kit include a fuse?
No. The confirmed protection device is a preinstalled 200A DC circuit breaker. A fuse is not included.
Are the BMS, touchscreen and breaker preinstalled?
Yes. The BMS, touchscreen, DC breaker and main internal wiring are preinstalled. The buyer still needs to install and connect the cells and complete all final checks.
Can up to 15 completed packs be connected in parallel?
Up to 15 may be possible only with matched batteries, coordinated BMS settings and communication, equal-length correctly sized cables, suitable protection and a properly engineered system.
