Aaron, I just upgraded from 2-200 amp hour Renogy LFP batteries to one 460 amp hour Epoch LFP battery. The Epoch is only slightly larger than one previous Renogy battery even though it’s more than twice the capacity.
One of my Renogy batteries died and they refunded my money. I didn’t want another Renogy.
I have room for two of these but don’t need 920 amp hours.
You might check them out, they have Bluetooth, low temp cutoff and built in heaters and a 10-yr warranty. Here’s the one I’m using.
