I feel relieved someone else is having the same problem as me. Very difficult attitude at my dealers service Centre- am off again tomorrow with all the info about rebalancing the battery and a record of my battery useage vs kms travelled to show I have lost range . My battery voltage has improved slightly with the charging at home from 425v to 431v but “please slow charge high voltage battery” warning light still coming on several times a day- service Centre just say keep watching the warning light?????Great info on this thread. I was getting the annoying "slow charge" message and red battery sign to. I also noted I was struggling to get even 85 miles on a full charge in E mode and I was get 4+miles p/Kw some times too. I don't use the heating/Fans but only in extreme situations.
This range was also during the mild weather in spring (before the constant rain!). I only have a granny charger and i've always charged on this but i've just checked my cars volts now and it reads 402V!!!!!!!! and the slow charge message popped up again and i only have 64 mile range!
I've just come back from the MG dealer today as they recalled it for the new BMS update and they said it will take 350 HOURS (yes 350 hours ) of charging to stabilize the batteries. The dealership said driving the car also counts as the re-gen brake also counts but not seen it mentioned on hear regarding the regen counting.
Sounds like this is going to take a long time to get sorted.
I also noted the dealers NEVER offered to balance the batteries for me the as per the MG paperwork in the posts above. The service staff who I found difficult through the whole process just told me to use the battery up and just keep charging it as normal and it will improve.
