VESC Toll app showing 100% all the time?!

Yep, Mobile vesc tool app for Android is showing 100% battery all the time. See the screenshot, the actual battery % should be 79%. Anyone experience this?! battery is 42v 10s6p pack.

Check if your battery s-count setting is correct


Yes it’s correct.

on both VESCs?

Yeah it’s a Flipsky 6.6, set up with the desktop vesc tool program. Never had this issue on previous setup. It could be a faulty nrf51 dongle? That’s what I’m using for telemetry.

But yes series is correct on both vescs as far as I can see unless I am missing something?

see on the bottom of your screen shot

“limited mode”

I don’t know what that means… but I’ve never seen that on any of my boards

Limited mode usually is when your Vesc firmware is older than the vesc tool FW.

Vesc fw 3.55
vesc tool 2.06 = limited mode


That’s correct, I have tried everything with downgrading firmware and upgrading firmware yadayada… I still reckon it a faulty nrf dongle. No big deal just it’s handy to know my battery status and range etc.

that is literally the only thing I use the app for… well that and log files…


Ok definitely something funny going on here, went for a spin this evening with 70% battery. Battery drained to 0% in less than 5km. That’s complete shite. I should be getting something like 20km on that rating.

Possible bad P group? Although I have a sneaky suspicion of a bad motor or sense wire as one is turning slower that the other…thoughts anyone?
