48V at 40Ah, this is quite the LiPo battery pack.  well, it was, before it self-discharged.  looks like about $1K to replace all those magic baggies, last picture can see the magic smoke has leaked out and left an aromatic grunge behind.   at least the BMS has a clever tab attachment setup.  searching for LiFe replacement options.  anyone recommend source for 20-40Ah that would fit roughly 210x210x150mm form factor?  only one cell has 2V on it, the others 0.2V at most, so no youtube pack puncture fun here.
