Have you tried breaking up the bank to see if just one of the batteries is the problem?
Yes. The 8D and one of the two 100s for sure and the other 100 is not quite so bad. I ran a repeat kettle test on each one individually at home until it crashed.
It is not like they decline steadily all the way down like they used to. All seems ok for small voltage drop under load until-- oops-- it is not ok.
I found a couple of wiring connections that were warm and tightened those, but it didn't change anything really for voltage drop crashing. Batteries for sure doing that.
I did the 20 hr rate tests on all three last April and only the 8D gave a sign of this problem (as described in the link to the old thread from back then in the OP of this one)
People on here who hate paralleling (I don't agree with them) will say the 8D ate the others this summer, but I don't think so.
I will have to do some backyard runs to try 50-90s without the higher draws and see if I can still at least do that. I don't know what I have here for going camping with at the moment. More tests!! :)
