Hello,

this week-end, my battery from the ST2 was on 89 %. (from 96% => 89 % without riding, just power-loss when in cellar).
So i connected it to the power. The light on the adaptor was orange in the beginning and turned after a while into green, so everything looked normal.
After disconnecting and checking battery, it was still on 89 %, so nothing happened.
This is not the first time i notice this. Everytime between first load and failed load, the bike didn't rifde, just power-loss while in cellar.
Other times, i did a ride until the battery was under 50% and then loading wasn't a problem.
Does anyone has the same problem? Or solution?
(I will try this evening with another adaptor.)

Having some experience with battery and charging routines, most charge routines are a 2-step process. Standard charging process until the battery is almost full, then swapping to a trickle-charging process to get the last few percents up to 100% (takes more time compared to standard charging).
Have noticed that the ST2 charging routine follows the same principle.

Orange led: charging to approx. 90% (I suspect)
blinking green led: charging from 90% to 100%

Suggest you leave the charger plugged in for another hour and I suspect you won't see the 89% anymore

Would not recommend to charge the battery to 100% each time if you're not planning to ride the bike shortly after. 100% means high internal stress-level to the battery-cells which can have a negative impact on the life-time of the battery.

* It stayed on the charger for already 12 hours, so that should be enough i think (and hope) ;-)
* I did plan a trip on Sunday-morning, that's why i did (try to) charge. Trip didn't happen cause to rain ;-(.
Kind regards,

Hi Raf,

When I picked up my bike it was 96%.
According to the shop it will be fixed in a future firmware release.
At 17% the screen suddenly went of. So I did a full charge again. It became 100%.
This morning I did my first time to work. It was 93% yesterday evening (-7% in 2 days without touching it). I plugged in the charger but this morning it was still 93%.

Today I had a actieradius from 40km (level 3)... sad enough I still had 4km to go... without support... heavy wind :-)

I hope this is because the battery is new, and needs 3 times charged from 0% - 100%.

Hello christian,

Seems that when battery level is "high" it doesn't load.
Don't now from wich point (battery-level) it starts to load again.

Kind regards,
