Hi,
I've been a "silent watcher" of this forum for some time and have learnt a great deal from all of the posts - thanks very much - it's great.
I would like to know if it's is acceptable practice to parallel two AGM batteries of different sizes e.g one 90 A/hr and one 120 A/hr , for the purpose of charging and or use. I have one (120) permanently mounted in the back of my Cruiser isolted via a Redarc which runs my fridge and have another (90) in a battery box.

Currently I charge the 90 with a Smart Charger in the shed every month but am wondering if I connected it via Anderson Plugs to the 120 if it would do any harm?

Any advice please and thanks in advance
