How about some on-point replies :?: Please :?:
You can try the IMA reset proceedure. Simply disconnect the 12v for about 1 min, then expect a forced charge. If the 144v battery is bad expect a return to your current condition within a few days. If its
really bad then the resulting forced charge will likely not be able to "refill" the IMA pack.
Now you've got to decide new vs. used and DIY (or with someones help

). And whether or not you want to go for the updated IMA controllers too.
Search eBay for current pricing, but with a bad IMA pack I'd expect you'd have to take that cost right off the top.
HTH!
