Loss of power, if a complete loss is something in the path from the battery is failing. Two reasons/symptoms. A high voltage reading on the EIS indicates there is no load on the regulator. That is it is not seeing the battery. And the second symptom of your dash going dead also leads to a bad path. A simple loose connection would be my first suspect. If you have a relay in the path between the battery and dash it could be failing or have a loose connection. In any case this is why my radio and gps's units had battery backup. If you have a schematic of your system it should be easy to come up with the most likely fault point. One trick to try to sort it out is to gently touch, tug, and tap around to try to duplicate the dead panel issue. Be very gentle. If it is a loose connection and some corrosion has developed then touching a loose wire can temporarily cure the problem. On the good side, if there was enough power to turn over the engine it is highly unlikely the battery is defective.

After shutdown I removed the cowling but could not find any problem. Reinstalled the cowling. The battery was showing 12 .9 v on the EIS.

I suspect I have a voltage regulator issue, or a bad interaction between the regulator and the battery. Any troubleshooting suggestions? Any way to bench test the regulator?

Just swapping the batteries without adapting the way it needs to be charged may lead to a short life of the lithium battery. That may be why Rotax does not want the use of that battery for their engine. For my electric tricycle, which has a lithium battery, I have a special charger that is just for this battery. Anyone out there with more knowledge about this issue?

You definitely need a special charger and generally these will individually charge or 'balance' each cell, as well as cater for the different voltages etc. I would think that any manufacturers would strongly recommend against straight swapping lead acid for lipo batteries for very justified safety reasons. I'm sure if you Google it you'll have enough material to read for days on why this should not be done. Regards, Matt.
