Greetings All, new to the forum and my first post. We have a 2001 Hawk that we got about 1.5 years ago and I'm making some changes, slow but sure.
I've been researching, read lots of old posts, but still unsure about my question.
We were on a trip to DV a couple of weeks ago, and our house battery died. We stopped into an RV place in Bishop and got a new battery. I believe it was the 3 way fridge that killed the old battery,(running on12v while traveling, but forgot to turn it off during a 2 hour stop). Only used propane after that, and have pulled the fridge out when we got home. At this point we have very little draw, just a fan and water pump.
We are replacing the old 3 way fridge with a TruckFridge TB51A, and I'm working out all the solar etc. Thanks to ski3pin for his great testing info!
I was going to put 2 6v in, but since we had to do an emergency replace, and they did not have any 6v, I now have one new 12v. Optima Bluetop AGM Marine duel purpose
I'd love thoughts on the best way to proceed.
Can I add a second 12v battery to this? It's dated 10/18 and was installed 3/05. The guys at the RV place thought it would be fine if we do it soon. Any Thoughts? If it's ok to do this, would it double our amp hours? (trying to wrap my head around solar planning!) The battery is rated C-20 capacity 55aH. According to ski3pin's tests, we can reasonably safely assume it will use about 15amp hours in 24 hours, so even the single battery should be ok for 3 days without charging? Am I understanding this correctly? I am electrically challenged! We will be adding solar, but that is a whole other kettle of fish in our old camper that is not pre wired.
Is it worth loosing the floor space to a second 12v? Expensive timing to go with 2 6v, but could be willing as I could use the 12v in my chicken coop hot wire solar set up when the battery that is out there dies. Or maybe run this till it dies and get the 2 6v then... decisions!
Thanks, this forum is just amazing!
