And that's the key. Understanding how a booster ckt works, and the battery C rating required to properly power them ...
You've got that right.
When I first came to the ECF, I didn't give Batteries all that much Thought. There all the Same... Right?
The I started to read thread about how Different batteries Really are. And what the "C" meant. And how to think about how many Amps a PV could pull for a given Carto/Clearo at a given voltage.
Really opened my eyes to what was going on.
Like I said, for me and the way I use my Provari, Many Non-IMR batteries are fine.
But if someone asked me what type of Batteries they should use, I tell them AW IMR's. Because they wouldn't be asking if they knew. And the AW IMR's are some of the Better IMR's out there for what Many people want thee Provari to Do.
