First Top Charge
I finally got my volt/amp meter wired in to my Mega Watt and started my first Top Charge. Initial battery voltage was 13.2v. Mega Watt was set to 15v. Turn-on voltage was 14.8v @ 33a. It quickly went ...

And again, I'll point out that battery management is like learning to use a computer - confusing and frustrating at first, then a laugh-a-minute later.

His intelligence is plenty high. He has learned how to manage batteries correctly and he loves it. The community now refers to him as a "Battery Guru".
I remember the look of horror on the face of the battery store owner when Jesus hauled in a 500-amp carbon-pile and Freas hydrometer to check group 27 batteries before he purchased one for his "lancha". Out of a stack of 7 batteries, Jesus, culled six, and cherry-picked the best of the breed.
Once-per-month top charging: Recommended constant 5 amp per 100 amp hours input for one-half hour via a trusted (battery backup for memory) interval timer, is plenty. That will free a lot of your time.
Storage temps of less than 0 C need a full forty minutes of 5% amperage. Pianotuna could use almost an hour a month. And a hot water bottle :)
