1. Introduzione e oltreview
This manual provides essential instructions for the safe and efficient assembly, operation, and maintenance of your HiXiMi 15kWh 48V LiFePO4 Battery Box. This product is designed for DIY solar energy storage systems and is suitable for various applications including RVs, off-grid setups, backup power, golf carts, home storage, and marine use. Please note that batteries are not included with the battery box.
The battery box is compatible with 174x72x207mm Class A LiFePO4 cells (280AH, 302AH, 304AH, 314AH). We recommend using EVE 280Ah or EVE 314Ah cells for optimal performance. The durable metal casing is made from 100% safe, non-toxic steel aluminum alloy with an anti-oxidation layer. The black model does not include wheels, while the white model (not this variant) comes with wheels.
A built-in smart 16S 200A Battery Management System (BMS) protects against overcharge, over-discharge, over-current, and short circuits, featuring an excellent self-discharge rate and integrated temperature protection. The BMS supports Bluetooth, CANbus, and RS485 communication, allowing real-time battery information monitoring via a smartphone application.

4. Installazione e assemblaggio
Follow these steps carefully to assemble your HiXiMi 15kWh 48V LiFePO4 Battery Box. Refer to the accompanying video for visual guidance.
- Preparare il caso: Install the four handles and two latches onto the empty battery case.
- Check Battery Cells: Before placing the cells, measure the voltage of each individual LiFePO4 cell to ensure they all have the same value. This is crucial for proper battery pack balancing.
- Insert Epoxy Boards: Place the epoxy boards inside the case. Note that the bottom two pieces of epoxy board do not need to be taped.
- Place Insulating Boards: Place two pieces of boards (one epoxy board and one insulating cotton) at the top and bottom sections of the case.
- Arrange Battery Cells: Place the battery cells inside the case as shown in the assembly video, paying close attention to the positive and negative sequence. Insert a piece of insulating cotton between every two cells.
- Install BMS and Wiring: Secure the front baffle using M6 screws, ensuring no gaps. Connect the BMS board and associated wiring.
- Connect Balance Boards: Place the balance boards (Board A on the left, Board B on the right) on top of the cells. Use M4 black screws to fix both ends of these boards.
- Install Busbars and Connectors: Place the busbars and connectors between the cell terminals. Lock the nuts as shown in the video, reinforcing all nuts with a torque wrench to between 6-8 Nm.
- Connect BMS Wires: Insert the terminals of the row into the rubber shell one by one in the order of 1, 2, 3, and 4.
- Connect Display and Power Switch: Connect the display and power switch cables from the front cover to the BMS.
- Install Fire Protection: Our new model includes an added fire protection component. Install it as shown.
