From Cells to Full Pack: Gobel Power DIY Battery Build & Capacity Test

Today we’re building the Gobel Power LiFePO4 Battery Case DIY Kit using the Cornex 314Ah LiFePO4 cells, and taking it from individual cells all the way to a fully assembled and tested battery pack. In this video, I’ll walk through the entire assembly process step-by-step, including cell placement, bus bar installation, wiring, and BMS setup. Once the pack is complete, we’ll put it to the test with a full capacity test to see how the finished battery performs as a complete system. This kit includes a 200-amp JK Inverter BMS, making it suitable for inverter-based systems, off-grid setups, and DIY home energy storage projects.
