I got the "Duracell Ultra 12V 110AH 800CCA AGM Deep Cycle Marine & RV Battery". You can certainly find less expensive batteries, but you want an AGM Deep Cycle with a good warranty.
Wayne Pumps sells a 75 AH (lower rated AH, so it won't run as long) but may be slightly cheaper.
I of course could be missing something, so I figure I would ask your opinion on my summation. Thanks!
That said, there's not many 12v ones when it comes to those units, and they (the 12v ones) tend to be cheap and low power so may not be sufficient. Most of your options are 24v and 48v systems…which a pair of these would work out great for…but if you want to run that sort of thing on a single battery, you are better off with a 24v battery and more hybrid inverter options rather than a 12v and being very limited. Something like 2x of these batteries, $500 or so 3000w 24v hybrid inverter, + your wire and misc stuff would be a great cost effective system for the capacity.
Tempted to get two more batteries for increased capacity at this price.
My only concern is disposing of these when the time comes and if it'll be a hassle.
I just noticed these batteries support 4s so a 48v is doable but you still have 4 12v bms. Not the ideal solution, but as long you don't cycle them daily they should keep themselves balanced within each other.
