I would welcome any analysis of the electrical performance in this flight data.

What are 'Back Volts'?
Why is the batt voltage stuck on 8.5 v when it spun the engine with alacrity upon startup?
Is the high amperage of the alternator trying to recharge the batt?
What about voltage excursions? Should I increase LR3 voltage or is 14-ish OK for SLA batt?
Anything else for concern?

Thanks

There isn't much point to posting an excel file when a graphical view gives a much better and easier way to interpret the data. Upload it to Savvy and post a link.

Thanks Sebastien.
Forgot about that resource. I'll repost this with the Savvy graphs if I can find the original AFS 4500 data file.
