Total electrical system failure

In response to one member questioning why the lights were off when I tested the Li battery at 7.46V, I reinstalled said battery today.  This battery has NOT been charged since the failure.  Upon reinstalling, the battery now had 8.2V.  The neutral indicator and running lights illuminated for about 15 or 20 seconds and then dimmed to dark.  Battery voltage dropped to .30V before I ceased the test.  Clearly the battery has some voltage left but little to no amperage capacity.  I plan to comm with RPM regarding charging the battery as it came from them.  I put the lead acid battery back in and the engine started right up.  The thought process here is leaning more and more toward Pat's experience of a heat related charging error.  A combination voltage and oil temp digital gage would be cool.  I need to find one that is appropriately small for a motorcycle.

Okay, so here I am waiting for a tow truck. Story is, went for a ride today. Toward end of ride, the engine started cutting out when rolling on the throttle but intermittently. Finally, on Skyline Blvd in Daly City the engine died at a stop light. I pushed it off to a side street and tried bump starting, no joy. Plus I smelled gas fumes from the exhaust. No starter action when pressing start button. The fuel and oil lights illuminate though. Soooooo, do I have a bad Stop/Run switch or possibly a bad kickstand switch, neutral relay or something else.
i carried a multimeter with me today. Battery has 12.7 volts.  Unlike last time it died, all light seem to work.  I'm attaching a pic of the cluster when I depress the start switch.

Yep, a bad run stop switch.....or circuit.
The oil level and fuel lights illuminating when you press the starter is the key.

If the neutral light illuminates, does that typically mean the neutral relay is working?
Just got home.  Nice driver.

I've never seen this type of motorcycle tow before.
