I discovered this brand probably on this forums, and put a
VMAXTanks MR137-120 Deep Cycle battery
into a Casita
While not a LifePO, it's pretty much a drop in replacement, and has higher lifetime, and more discharge cycles.. You can read all the benefits on their site.
Anyway.. I now have a 2007 Bigfoot
17.5, and wanted to see what biggest battery
I can fit there w/o modifying anything.
area is 8x13, and looks like you can put a 155AH
XTR12-155 12Volts 155AH Deep Cycle, XTREME AGM Battery ($400 on their site)
plenty of height in the box..
I don't believe this battery requires a box
12.9"w x 6.9"d x 10"h/10.8th*
I had a SLR100 12Volts, 100AH Deep Cycle, Solar
AGM Battery lying around and that fits too.
Anyone else fit anything better (more capacity, higher quality battery)
something with dimensions around 8dx13wx15h could have been over 250Ah
