I disagree with this. The battery has a 7 year warranty, the latest BMS has lowered the upper end to the point where regen works when the battery has charged to 100%. I always fill to 100%.I agree with this. It's simply a fact of lithium chemistry, unless there is some special sauce in there to somehow prevent the bad reactions, and I don't think that any exist as yet.
I actually don't want to argue this one. I know a lot of people don't have as much time as I do to fiddle with the end of charge. So for them it's almost certainly not worth worrying about. For me, it is.
As Kithmo said in post #10 'what's the point of only using 80% of the battery at the beginning of its life when you may only have 80% to use later down the line when the battery is older.' You are effectively reducing the range of your new car by 20%, not in my world.
Range is King, you do not want to be stuck down a wet, cold, country lane in winter because a diversion re-routed you and you have no charge left.
