Low Battery Failsafes

Charles Gavin · Jan 10, 2016

Does anyone know how to increase the Return to Home failsafe which happens when the Solo reaches 10% battery? I'd prefer to have it up around 25%-30% just to be safe and also so I can use it while surfing on my own.

You can hit the RTH button at any time you like.

You could change it using the Tower app on Android. Or with Mission Planner on a PC, or APM on a Mac. I'm not sure if the Solo app would reset the param the next time it connects, but I don't think so.

Good list to have thanks Erik.

Does altering parameters void the warranty ?

3DR has stated that only if a changed parameter is found to be related to the cause of a crash. Certainly reasonable..

Thats good.
I might have to start having a play.
Not that my warranty is good anyway, Im not even running original motors, but its good for those that want to have a tinker.

So what kind of battery capacity would translate to roughly 25% battery? I'm fairly new to using the Solo so I'm not sure what mAh gives in terms of battery percent.

Off the top of my head I can't recall. 0.1 volt makes a difference, so I don't want to throw out a number because being off by a little could actually be a lot. I'd focus on volts though. FS_BATT_VOLTAGE

I'd fly 3 or 4 fully charged batteries and note down the volts (and mah) at various percentages.
