I recently bought an used 2009 model E-Max 90S with only 2000 km on it.
Upgraded it with Lithium Ion (14S) from an electric car (VW E-UP) and it works really well.
I might go for 15S later on but 14S actually works well with the original charger.
Battery is 50AH and gives about 70 km range. I could probably fit double if this but do not need 100km+ range so i prefer to have an very light bike instead of adding more batteries.
Now to the questions:
1. The motor controller has FW V1.11 and i want to remove the speed limiter. The controller is the new kind filled with black gue.
Does anyone have the right tools and knowledge to do this programming?
2. The resistors on the controller box gets really hot now. I mean so hot there is smoke(!)
(See two resistors on the left side of the blue capacitor in picture)
This can not be normal? It only happens with main headlights on. I see there is H3 12V 55W bulbs in there, is this original?
3.If i go full throttle from stand still with boost mode on the motor controller cuts the power 1-2 sec due to over current when it reaches about 10km/h. If i go full power above 20km/h it works fine.
When boost mode is off, it never cuts the power. So only in boost mode, and in low speed at full power.
This seems also not normal? Its no problem using the bike, just needs to be a bit carefull with going full power right away with boost.
4. What is the recommended fuse for the battery pack? The previous owner had fitted an 80A fuse. Probably not original?
Anyhow the 80A fuse melted so i now run an 150A fuse.
