Very few if any 5er's use 6 volts. They may have 2 6 volt batteries wire in series to give 12 volts but nothing in them runs on 6 volts. you would need to jump 12 volt to 12 volt.

My unit has two 6 volt batteries, four 6 volt batteries actually. Hopefully the solar will keep the batteries up? But great to know the truck batteries could be used if necessary.

Thanks guys

It takes two 6v batteries wired in series to make a 12v. If you were to jump them you need to connect one cable to each battery NOT both cables to one.

To maybe pull in a slide or raise the jacks? Why not? But, your cables are going to get REAL hot.
Hot? Running jacks?


That's 25 foot of cable that'll be needed. You should see how hot my in bed transfer pump cables would get....and they were only 12' long.

Together it is one big 12v battery. Connect on the right terminals and all will work fine.

Why are you wanting to “jump” the trailer? If you are concerned about slides and jacks with dead trailer batteries you could plug trailer umbilical cord into the truck (with truck running) and have enough power to use the jacks and pull in the slides.

I guess so, but that doesn't jibe with the comment above about how cables will get hot. Hot comes from a lot of amps. Umbilicals don't carry a lot of amps.

If the trailer battery bank is low, for whatever reason, plug into the truck as per usual & run the truck as fast idle for a bit before trying heavy draw things like slides.

I've checked the amp draw on my Momentum when running the slides in/out, and it pulls 65 amps. Yeah, I think those jumper cables will get pretty warm. [emoticon] If those trailer batteries are way down, you will be pulling some pretty high amps.
