Hi!
I get some suggestions, that maybe the cells are not ballanced correctly. So went to 0% let it stand for couple hours (bottom balancing?) and charged it to 100% let it stand for hours pluged in (top balancing?)
So after that went to test, i get the linear power, so i was very happy
But.... i drive ~30km a day, so for 5 days i did not charge it, yesterday i planned to ride to forest, the battery was 48%
Whent to highway, pushed full throttle, and the same issue happened, for tiny moment full power, then goes down and went a little up, like Yo-yo. Trip to forest around 20km, so tried full throttle at every straight, some times was more linear power, some times yo-yo. Getting back from forest, i had back around 10km and around 20% charge, so no problems wright?, and at 20% the limp mode was on my dash ? ( i have seen it at very low stay of charge, but at 20%) And there was something written about low cell voltage and balancing... So the power was very low, at full throttle i get maximum speed ~85km/h....
I put it on charge and today with 100% drove for testing, everything is great again, tried full speed, everything is good.
So i guess something is wrong with balancing the cells, if it is balanced, then everythings works, but if i dont charge it for 5-6 days, then it has some issues.... So what to do, charge everyday to 100% so the bike will balance the cells every night?
