I do have 8035. I am storing not more than 3 days in 100% as you check my stat.
Never the less this is not the main point.
The point here is that Saturday it was 9 cycle and 100% and Sunday it was 10cycle and 90%.
That is well ... excluding the chemistry and physics for sure. In one charge it can not degrade 10%...
I do make Radio Controlled car hobby, and there we use Lipo as well. Those batteries are much much simplier Lipo-s than ebike , after 4 years and hundreds cycles I am still able to put ~6300mah into 5400mah battery... which if you consider losses heat etc, still shows like a brand new one.
The first thing what I have learned there is to charge always slow as possible and do cell balancing. Store in 70% and in the fridge. (somebody wrote that before) okay they are smaller ...
What I do not understand here, that why we dont have 70% charge up option. Like in RC in my charger I do have storeing option.
So the charger charge it up to 70% slow, or its discharge it to 70% slow. and than it switch off.
Also there is cell balancing option ,where each cell is charged individually to reach ~3.8v
Today I made a ride, and also I made an experiement. I did a big boost up climbing, and I have measured the battery and the engine as well.
I did not measured high temperature at all... both of them were 26Celcius, where outside was 12C.
I dont think it is related to heat, also I dont think it is related to charger, due than other types would suffer too with the same type.
As I read this thread through most of you own faster charger, I do have slow charger, and all of us have 90% after 10 cycle with the type 8035...
Again mine dropped 10% in one day.
Gents this is smelly to me from Shimano...
