Do's and Don'ts for e-bike battery care. What do you do to keep your battery performing at its best?

Whatever the reason, the point was that this is a 4 year old battery that has never had that 80% option, is a small one so has frequently been charged to 100% but 170 cycles and 2800+ miles in it’s still 100% healthy.

It’s just been used to suit me rather than the other way around.

The motor sounds like a bag of spanners though, motors are what concern me! I wonder if leaving it turned off wherever possible on a ride, only using Eco and not ever washing the bike would help? Imagine that!

But it's not still 100% healthy though. That number is a lie. Even if you had not used the battery at all and just stored it at the perfect SOC in a fridge, it would still have lost some capacity. Lithium batteries that don't degrade whatsoever just don't exist.

You can use your bike how you like. Dunk it in a pond to wash it if that's convenient for you and leave it switched on 24/7., but this thread is about how to best look after the battery. Charging it to 100% and storing it full is not the best way to look after it, regardless of anecdotal evidence.

For goodness sake…

It is 100% for the purposes of my ability to use the bike as it was designed. It has the same range visible to me as it always did, of course it will have degraded, but if Specialized are hiding that degradation from me in the way of a decent BMS, why do I care? It doesn’t get visibly any bigger to you because you’ve been afraid to use it below 20% or above 80%.

You don’t, unfortunately, have the ultimate say on what gets posted on a given thread, I’m free to interject things I think relevant to the topic.

You’re relying on a lot of anecdotal ‘evidence’ and research, battery tech is moving on all the time, the internet myths and legend around it unfortunately don’t. You’re also scaremongering unnecessarily, in my humble opinion.
