Mix different capacity batteries?

[DavidD]

I have a 12v 200 Ah lithium battery in my trailer. Can I add a 12v 300 Ah battery in parallel (of a different brand) to make the bank 12v 500 Ahs ?

Yes
I have been doing it for over a year.

I want to do this too. I have 2x 100AH 12V Chins Battery's and just got an Enjoybot 200AH 12V battery.
All 3 are near new. Just joined and was looking for confirmation that i could parallel them all. thanks!
