Good point. If the engineer was trying to make the point about why 100% charging was a bad idea it would have been natural for him to use the higher 4.2v charging as an illustration. It's quite dramatic and definitely gets your attention.planet4ever said:I wonder if we might not have a semantic confusion here. Perhaps by "fully charging" the Nissan engineer meant 4.2v, while the LEAF literature means "all you can stuff in at 4.1v" when it refers to 100% charging.
