Let’s me summarize again.
1. We got 4 of battery packs from TTE, after we checked, we found that one of them is broken (Protective relay is not work, may be caused by wire, relay or broken BMS ASIC)
2. We can use only 3 packs for capacity 60AH (=old Panasonic pack), so this is not affect us too much. (Just we cannot use it as 80AH configuration)
3. Charger they sent is designed for use with 3 packs (So it match with 3 packs configuration, not 4 packs configuration)

For the solution we have following candidate
1. Send back for replacement
2. We disclose the battery pack and try to fix it ourselves
