Whats the point of following the manufacturers ebike battery maintenance guidelines if theyre just going to be outdated in a few years? Are we just supposed to blindly trust the companies that are only looking to make a profit off of our battery replacements?
Ive seen some people swear by letting their batteries completely drain to zero before recharging, while others claim that keeping them between 20-80% charged is the way to go. Whos right? And why are the manufacturers being so secretive about the actual chemistry and materials used in their batteries?
Can we really trust the built-in battery management systems to keep our batteries healthy, or are they just a fancy way of saying we dont care about your batterys lifespan? And what about the impact of extreme temperatures on battery health? Is it really worth the risk of leaving your ebike outside in the blistering heat or freezing cold, or should we all just be storing them in climate-controlled garages?
It seems like every expert has a different opinion on how to properly maintain an ebike battery, so lets get real here - whats the actual science behind it all? Are we just being fed a bunch of marketing nonsense, or is there some real substance to the claims being made?
