FixHub battery - replace cells

I purchased this station when it first came out. it sat in a drawer for eight months. it was 90% charged or full when i did so. when pulling it out, it was dead. I was reading less than 2V from the cells.

Replacement battery packs were sold out here so i bought a DIY spot welder and six Molicel batteries. I replaced the cells and tabbed it the same way i saw it when i disassembled. I can read 4V from pos-to-neg on each cell. they all have the same chemistry (i drain/charge checked them).

I get 2.0V across the terminals/connector but I can't get the power station to come up.

I was able to hard reset the station and upload the latest firmware (1.4.3 at this time, i believe).

Is the BMS on the battery dead? is the pack not serviceable?

I would've just bought a replacement pack and called it a day but I'd like to try and salvage something from my attempt here.

Any info would be appreciated. Thanks.

After looking at photos and reading the label I previously misplaced, I realise I'm not getting the right voltage because I didn't wire the batteries correctly (the centre two inverted)! I had a moment of derp. Completely disregard my original post.

the battery pack should .. 10.8V 56Wh 5200Mah
