Question...do I use the same positive and neg. from the same battery to use electric tongue jack, solar panel, etc. in a 2 battery bank I know they say to use neg. from one batt. and the positive from the other battery when charging with a charger, is this correct?... my 2 batteries from the dealer is in parallel, the trailer and electric tongue jack are connected to one battery not split between the 2 batt....confused! ------------- Xxxx7 |

Connect to the same posts that everything else is connected to. It is TECHNICALLY better to hook neg to one and pos to the other when installing dual 12v's, but within the constraints of how TT batteries are used, the way yours are hooked up is fine.

Is it better to use one battery at a time or use them hooked up in parallel? ------------- Xxxx7 |

It's best to connect the batteries in parallel and use them both simultaneous. Peukert's Law states a battery has more capacity if discharged more slowly. When you use the batteries simultaneously the load is split between the two and you are discharging each battery at about half the total rate.

That's what I thought in November furpod said it was ok to put connections on one battery because of how to use the batt rise (see above post in November) the batteries are hooked up in paralell ------------- Xxxx7 |

Furpod is also correct. With the batteries connected in parallel, technically there is a slight preference for connecting to one positive terminal and the alternate negative terminal. In normal Rpod use the difference is minimal. The primary point is to connect both batteries together and use both at the same time.

...and also having the interconnect wires of the same gauge and length. That makes the inline electrical resistance the same for each battery, which means the voltage drop of the wiring will be the same. |

Our original battery has died (our fault). We want to install 2 batteries so we can do more remote camping, having previously been 38+ years tent campers. What size do we need - 2ea 6v or 2ea 12v? Any particular brand recommendations? If we also use propane when possible, how long will dual batteries last? Do we need a cut off switch as I've seen mentioned in some posts? Also, has anyone invested in the solar panels? Are they worth it? Any help will be appreciated! We love our 2015 178 - gets us off the ground, out of the rain, and has a bathroom  . But it's small enough to keep the "camping" in our trips - we still mostly cook, eat and sit outside. ------------- Nancy & Dwight 2015 rpod 178 2013 Tahoe LTZ |

I currently have 2 12v deep cycle group size 24 batteries and expect 3 - 4 days out of each depending on how cold it is, if we get cold nights (in this scenario 35-50 degrees) 3 days/battery. Warmer nights 4 days/battery. Would recommend acquiring 6 volt batteries, this is what I plan on doing when mine bite the dust; they are now 6 years old and still work fine but I know their end is coming. ------------- God's pod '11 model 177 '17 Ford F-150 4WD 3.5 Ecoboost Jim and Diane by beautiful Torch Lake "...and you will know the Truth and the Truth will set you free." |
