Bike speed "current limited"
« on: December 13, 2017, 01:13:04 PM »

I have a 2017 model FXS  ZF3.6 modular with one battery pack. Supposedly the top speed is 120km/h sustained. This is a fairly new bike (2 months) with fairly low mileage.

On a few occasions the bike has stalled out at a much lower speed - twisting the throttle has little effect.
Yesterday the bike limited to about 71km/h on a slight downhill, and later to about 65km/h on a bridge where many vehicles go 80. Kind of embarrassing.

The motorcycle log as downloaded via the Android app showed messages such as
 2017-12-11T19:23:13 Batt Dischg Cur Limited 133 A (51%), MinCell: 3485mV, MaxPackTemp: 12C

Has anyone else seen this ?
I believe adding a second battery module would probably fix it, but that's somewhat expensive...

My experience is that it depends on the state of charge. A full single pack is usually strong, but below 20-30% not good. I run two packs if I'm going to go fast on the highway. Single pack for twisty back roads is great.
