I'm planning to work from the road and that means I need power. I'm a web developer by day so I need cell service and my laptop. A GoalZero Yeti 500 would probably do everything I need... but I can actually build a dual battery system for about the same price. I replaced my starter battery last week so now is the perfect time to buy a second one and tie them together. I'm going pretty simple but leaving the door open to future improvements. I gotta say that I have learned a LOT over the last couple of weeks and I owe much of it to the PO of my tent (thanks Luke!) and to @Bullzi. Thanks for answering a bunch of noob questions and for all the photos of your setup. Another shoutout goes to faroutride.com... this is an amazing site for learning about electrical builds (among other things). I have used this wire size calculator extensively while planning the build.
The idea is to tie the batteries together with a 0 awg cable, rely on low power needs and solar to keep them topped off, and carry a battery jumper just in case (I have a Noco GB45X which works great). If, somehow, I manage to use enough power to need to jump the batteries then I'll consider another solution (Blue Sea ACR, Renogy DCC30S, or maybe a Redarc unit).
I ordered another Blue Sea panel (I already have one and I like the fit and finish), a couple of fuse blocks (one for the front eventually), a big circuit breaker for the front, and stuff for the new battery cables I need to make. I also spent way too long mapping all of this out using digikey.com. I found it really helpful for thinking through all of the possibilities and keeping track of my notes.
That's all for now! I need to order some LEDs and do some mechanical baselining. After I complete the electrical build next week I'll do a shakedown run and tweak before the end of January.
