I have a Discover AES 44-4800-3000 battery with less than 100 cycles that is showing one bad cell (0V) out of 16 (the rest are roughly 3.34V). I've had extensive conversations with Discover tech support and basically they are not set up to repair these and are very reluctant to offer much information or support for DIY repair. It's maddening and unacceptable to me that a virtually new $3,000+ battery is considered unrepairable. I did mange to find out that the cells are made up of 26650 3.2V 3.8aH cells- I think 16 in parallel. The battery case itself is steel and screwed together. I've opened up the case and located the bad cell by voltage testing, but that's as far as I've gotten. Any advice, experience, guidance would be much appreciated. I'm located in the Bay Area and would be open to paying someone to repair it. Many thanks
