AGM Mystery Capacity Crash Below 75% SOC UPDATE

Thanks Mex, that is exactly the info I needed. Very helpful.

So I will try it next time out, based on that advice. Will add my two "spare" 27DCs (100AH each) to the bank for when camping, keeping them separate at home. That should hold the whole thing above 75 along with less use of the kettle (stove top instead) eg. Keep that going for as long as it lasts.

Looks like a new battery set early next year. ( Which is ok)
