Would you still do the Genesis Dual Battery?

[chorky]

Just hoping in here real quick half way through my vacation. This is the second week of two week long camping trips separated by a standard 5 day work week. With the 175ah of AGM batteries (via the genesis system with a third aux battery of 115ah), with running the engle fridge during 80 degree day's plus a water pump and water heater for dishes, drinking water, and showers nightly, each morning after getting to camp around 1300 the previous day I would wake up to still having 12.6v at the lowest. With these specific batteries able to accept a 35ah charge, and day trips ranging around 2-4 hours plus a couple hours of charge via a 100ah solar panel at about 4.5 amps, batteries never once fell below 12.6v. Just a datapoint and some food for thought. Trip info will come soon in my build thread but probably in another week or two. Ok back to vaca fun.

It’s not bad batteries. Actually I made a lot of short trips today between schools. I’m the wireless engineer for the whole system. Getting ready for school to start. One ten mile trip and it’s all charged a fine.. funny I just happen to notice it right after the praise.

Well.... That's one good thing is that it's not your batteries!!!

I only run a Dometic 35l fridge/freezer when camping so my energy needs a very low. I was unhappy with battery options since none fit under the rear seat so I made my own Lithium battery. I purcahsed the battery cells off Aliexpress, and the BMS though another site. total cost for 135Ah was about $600. Add $250 for the Renogy 50Amp DC-DC charger with MPPT and I'm at $850 total. the 135Amp battery is plenty to last about 100 hours of use with my Dometic assuming no charge that whole time (about 4 days). Building the custom battery was great too because I did fit it under the rear seat, and all I had to do was run a 12v outlet to my truckbed.
