Mex's 20% AGM Rule Sucks.
Mex says deep cycle AGMs need to be recharged at a 20% of Bank AH rate even if they are not Lifelines (which do specify that). My AGMs are not that brand, and no mention is made of a minimum charg...

JimBollman,
What is your camping style?
How much capacity were you intending to add?
30 amps charging would easily service 150 amp-hours of battery bank.
I got tired of laying in the snow to check my flooded. I'd NEVER switch back.
As the batteries charge they start to "push back" and limit the charge rate automatically.
On a flooded jar that happens at 85% state of charge--limiting the rate to 15 amps per 100 amp-hours of battery bank. On an AGM the number is higher--tapering of charging probably happens at 92% soc.
There is at least one member here who uses a 'stock' PD converter and it successfully charges his agm bank.
As for the rest of us battery nuts, we love to "dance on the needles".
