The mppt does not affect charging. It affects power input into the
system. So no there is zero impact on battery health.
Richard, here's a partial log using panelpwr from a charge using the latest
firmware. Unfortunately today is pretty cloudy here, so it wasn't the best
day for solar panel testing. Hope it's useful in some way.

How does this behave when it encounters an external charger which may be
inflexible in terms of voltage or current generated?

There is one known problem. On your very first flash you might lose the
