This 3.3kWh 48v LiFePO4 PCB Tool Box Kit allows you to use multiple (x9) 16v OBX-E packs (sold separately) to build a powerful and portable Tool Box 48v battery system. The kit will connect to up to x9 packs in 3s3p configuration. This allows you to build a large booster pack for the very popular Bluetti AC200 or EcoFlow Solar Generators. You can also use this kit to build a stand alone 48v battery for any application of 15A or less. The PCB board is fully populated (no soldering needed). Tool Box sold separately here.

Includes a "toolbox faceplate" you can install on the box with a built-in battery state of charge meter, 250v fuse, ON/OFF switch, 48v output to PV input on Bluetti AC200P.

Also includes a bonus x5 pack Initial Balancing Charge area (left side of main board) for use with an 18v 2A DC power supply with 5.5mm x 2.1mm round jack connector, to be used for balancing the packs before connecting to the main board.
