The 100lb 12V 135AH AGMs I am using weigh 16 lbs 8oz per cell. Thick or thin plates, I have no idea. There are two interesting limit specs; 800A discharge for 5 minutes and 50A on charge.

thats even higher peak rating than mine
my 105lb 135Ah AGms are rated 500w per cell for 15 minuts
thats 3000w or approx 300 amps for 15 minutes to reach 10.2v

either way
we are packing a lot of amperage , anybody want to do some stick welding

i use wire feed with a small Lincoln welder, never learned to do stick

I followed your lead on deploying used AGMs. Mine are Eaton 12V 500W.

I paid $95 ea for two of those 5yo batteries in Sep 2015.

Don't you find it odd that the 800A discharge might indicate thin plates whereas the 50A charge limit might indicate thick plates?
