We all know modern day engines go on for ever, if change the oil and filter at the correct times, they are not a battery, but under hood batteries last usually 2+ years in LOS, where is the battery tech there...?
Seems EV rides with early failing battery pack can be from a heat problem, better EV's have a cooling system built in, I'm sure MG has that. ????
I hate to mention MG again, but they guaranty their piston rides for 7 years in the UK, only 4 years in LOS, or 100,000miles, I wonder why..????
