It seems like the warming is more when discharging from the description so far. battery temperature went up and stayed up in use, not so much at charging? Even that limited charging current is higher than the in use discharge discharge current - again only by description of times and battery temp. Maybe some cooling when charging and either they forgot about discharge heating in use , or the Maths said the lesser current discharging wouldn’t heat them up so much so save on the fans and get another 10 miles range? Maybe the one test driven is faulty? Anybody else had a good go in one yet?
