EU Stock Apex Stackable 48V 51.2V DIY LiFePO4 Battery Box Kit with JK PB2A16S20P 200A BMS

What Is the EU Stock Apex Stackable DIY Battery Box Kit?

Short answer: The Apex stackable DIY battery box kit is an EU-warehouse enclosure and component set for building a 16S, 48V-class / 51.2V nominal LiFePO4 battery. It includes the JK PB2A16S20P 200A BMS, 4.3-inch touchscreen, Bluetooth monitoring, communication hardware, busbars, insulation materials and the listed assembly parts.

This listing is for a DIY battery box kit. LiFePO4 cells are not included. Cell dimensions, terminal position and busbar alignment must be checked before ordering and assembly.

Quick Check Before Ordering

Confirm the exact cell brand, model, dimensions and terminal layout before payment. If you also need compatible EU-stock cells or want to check inverter communication, please contact Docan Tech with your cell model, inverter brand and delivery ZIP code.

Apex DIY Battery Box Key Specifications

Which LiFePO4 Cells Fit This Enclosure?

The enclosure is intended for 16 prismatic 3.2V LiFePO4 cells. Common compatible examples include EVE 280Ah, 304Ah and 314Ah, REPT 280Ah, Sunwoda 314Ah and REPT Battero 345Ah cells. A typical compatible cell width is around 72 mm.

Capacity alone does not guarantee a correct fit. Check each cell's width, height, depth, terminal spacing and terminal position against the enclosure and busbar layout before ordering. The completed battery's nominal energy depends on the selected cell capacity.

JK 200A BMS, Touchscreen and Communication

The included JK PB2A16S20P BMS is designed for a 16S LiFePO4 system and provides 200A current management, 2A active balancing, protection functions and Bluetooth app monitoring. CAN and RS485 are available for communication with compatible inverter systems.

Inverter communication depends on the exact inverter model, communication protocol, firmware and BMS configuration. Confirm compatibility before assembly rather than relying only on the inverter brand name.

Stackable Design and System Planning

The cold-rolled metal enclosure is designed for a compact stackable installation. The current specification lists support for up to 15 units in parallel when the BMS settings, firmware, communication, cable lengths, protection devices and inverter limits are matched across the complete system.

Parallel-system design should be checked before installation. Do not assume that enclosure stacking alone makes multiple batteries electrically ready for parallel operation.

Assembly and Safety Notes

• Use 16 matched LiFePO4 cells from the same model and batch whenever possible.
• Follow the cell manufacturer's terminal torque specification; do not use a generic torque value for every cell.
• Verify cell polarity, insulation, busbar placement, BMS wiring and fuse installation before energizing the system.
• Match cable size, protection devices and inverter current limits to the complete system design.
• Assembly and commissioning should be completed or checked by a qualified person familiar with high-current DC battery systems.

Apex DIY Battery Box FAQ

Is this a complete 51.2V battery?

No. This product is a DIY enclosure and component kit. LiFePO4 cells are not included, and the buyer must complete or arrange the battery assembly and commissioning.

Which cells can fit the Apex stackable box?

Common examples include EVE 280Ah, 304Ah and 314Ah, REPT 280Ah, Sunwoda 314Ah and REPT Battero 345Ah prismatic LiFePO4 cells. Compatible cells are typically around 72 mm wide, but the full dimensions and terminal layout must be checked before ordering.

What voltage battery can be built with this kit?

The kit is designed for 16 cells connected in series, creating a 48V-class battery with a nominal voltage of 51.2V.

Which BMS is included?

The listed configuration includes a JK PB2A16S20P 200A inverter BMS with 2A active balancing, a 4.3-inch touchscreen, Bluetooth monitoring and CAN/RS485 communication.

Can the BMS communicate with my inverter?

CAN and RS485 communication are available, but compatibility depends on the exact inverter model, protocol, firmware and BMS configuration. Confirm the inverter model before ordering.

Can multiple completed batteries operate in parallel?

The current specification lists support for up to 15 units when the BMS settings, firmware, communication, cables, protection devices and inverter limits are matched across the system.

What are the product dimensions and weight?

The confirmed product dimensions are 85 x 55 x 33 cm. The listed weight of the enclosure kit is 23.6 kg.

Are all assembly tools included?

No. The listed box components and fixings are included, but the assembler still needs suitable hand tools, electrical test equipment, personal protective equipment and a torque tool appropriate for the selected cells.
