I like to deplete the battery now and again, I could be wrong but I cant be arsed with charging every ride, I guess it depends if you have an epic ride planed the next day.
From fully charged the other week I managed 4 small rides totalling 75 miles with 16% battery remaining.
Loads of riding without getting hung up on charging every night
That's a bosch 625 2020 system in a cube bike, I guess all bikes and batteries are different but don't let them rule your your life .
It wasn’t an ad, it was the source of the graph.
Me neither. I just make sure if it's idle it's in a wide ballpark area of 50% not 100%. That's not difficult.
Yes it is but hardly known at all in the wider world.
And that's perfectly fine. If I tracked all devices and attempted to keep them all at around 50%, I'd get no sleep. But it's easy to keep a car & a few bikes at 50% until required & charge upwards to 80% or 100% before driving or riding as required.
It's pretty easy for me. I use a timer for the ebike, charge it to 60% after most rides. Once a month or longer I charge it to 100% and generally do two rides on that before charging again. For my phone I just use the timer on the phone to check the amount of charge - I generally charge it to 80% (when it drops to about 30% or less) because it's using energy right away.
Thanks for the article .. as someone who has always charged phone batteries et al to 100% and never cared about taking them off charge that's very illuminating. Surprised that experts seem to say keep at 50-70% unless you really need to.
I take it you don't ride very far then!!
My usual circuit is 20km but has a lot of climbing. I only use eco and that is in the 2nd lowest setting. Sometimes I use trail if I'm sessioning an obstacle. Sometimes when riding with a friend I stay on trail - it's a good match for his setting - then I can use around 80%, but not often. If riding with him I generally charge to 100%. When it gets drier I have even more climbing because of a different route - I'll probably have to go to 70% then; I forget what I used to do. Far is subjective. It suits me, still takes me two hours generally (includes sessioning jumps and technical challenges), but I'm not in a hurry. It actually keeps me pretty fit, for example I find a 40km urban jaunt on my ancient mtb with 2.3 balloon tyres pretty comfortable.
They won’t. Charging to 100%, especially if left fully charged, expect 500 cycles. Charging to 80%, expect 1,500 cycles. That is the difference between lasting - or not.
That would be an achievement with a Spesh pack. The BMS and assembly don’t like being repacked and looks more like a job for a precision robot.
4 years warranty on a battery is extremely generous for electric bike packs but you generally can't make a warranty claim for capacity loss - unless you fry a cell & it's a drastic loss. Capacity fade is the main avoidable outcome. Cycling in the 45% - 65% range & charging to 80% up to 100% before you ride is a very very easy way to substantially reduce capacity fade.
That isn't for all specialized though is it? I thought it was just for models that have troublesome motors? And for those that do get the extra 2 years on the motor, is that also for the battery?
I doubt its the same with ebike batteries. Car batteries cost lot of money to replace (especially if you directly compare them with ebike batteries) and it makes more sense to use such method with cars as is not that big problem to have a little extra weight to carry around and to make batteries last 5+ years while charging it almost every day (you'll probably produce much more charging cycles as you will ever have on ebike battery). But with ebikes every kg matters and you also want as much range as possible, so I think they also get actually charged to 100% cell capacity, otherwise charging the last bar wouldn't be so super slow ...
It sounds like a safety feature, if you mean you'd like to squeeze in that extra % and disreguard the safety aspect? If you're talking charging to 60% or 80% a cheap timer is good for ballpark +/- 10%. That's what I do.
I charge at night (cheap), but since my rides (and batterys) are so different, I have no idea how many hours to charge for, to reach a good end point.
So thats why I would like the BMS to do that for me
Good luck with 1500 charges Spesh are quoting 300 Charge cycles till you should see any drop in performance, and by 'charge cycle' they mean from 20% which is when assistance cuts out to 100% which is when your charger 'Automatically' stops charging it. As for Repacking its only a matter of time.
That - or two years - is what the battery is warranted for, but that doesn't mean we can't get more life out of it by careful management.
It seems to be well documented and realistic in the realms of research papers.
