2 different size batteries (1 Viewer)

[Ivory55]

Am I right in thinking you can not have 2 batteries new ones of different size joined together, ie 100 amh and a 240amh. It’s the size of the locker space I was thinking of.

Size doesn’t matter but type and age would be better matched.

So it don't matter if the CAPACITY (Ah) is different for both 12 volt batteries in parallel, they just add together, ie 110ah and 80ah become 190ah, still 12Volt
