Two addtional 100ah batteries in 320s for 400ah total!

Has anyone added 2 more 100ah LiFePO4 batteries in a tab 320?  I'm looking to place them in the space in the rear under the folding seatback.  Looking for mounting ideas since the batteries would be setting on a little slope.  Also wondering about the best route to wiring them up.  Trying to keep the wiring runs balanced since the extra two batteries will be phsically 4-5 feet away from the stock two batteries.

PS, I want to run the A/C for more than 4 hours at night without running a generator.

Thanks!

Hi, 

I installed two in front of the Air 8.  Maybe you can find two with the Ah you want to fit the footprint for this location .  There is more width that I used for other items.  Or maybe you can get a footprint to mount 90 degrees.  Maybe put two in front of the Air 8 and one under the bench in front.  Correct, during my test with the Air 8, my usage  showed about a 3 1/2 hr run time.

That's where I put my inverter, along with a 4" exhaust fan that kicks in when the inverter is on. I plan to replace the exhaust hose with one a bit longer, so it van lay on the inverter, for even more ventilation.

Definitely a great place for a couple LiFePO4 batteries, assuming that if the four batteries will be configured in parallel, all four will match up properly.
