I'm having some issue with sourcing group H7 battery locally 
(what came with the car), but most stores have the bigger group H8 battery in stock.
I know this is a supported battery size in CEM "H8 AGM Exide 95Ah 850CCA", so I'm just wondering is there more to changing the battery size than changing the config in CEM?
VIDA product specification is a little unclear on how the charging circuit works, my understanding is that the CEM takes reading from BMS and then it can command alternator control module to change the supply base on the charging algo determined by the CEM?
I think the H8 battery is about 15ah bigger than the H7 capacity wise, I suppose it might be fine if I just leave it as it, but I figured if I am doing it, I want to do it right.
Thanks in advance.
