I have decided to add a second battery in the bed of the truck and was thinking of using these 2 pole connectors to connect it to the current battery located in the camper battery compartment. Anyone see any problems using this type of connector?

Use this female plug mounted under the wing of the camper next to the battery box.


Use this one coming out of the battery box located in the bed of the truck.


Thanks.

May I suggest Anderson connectors. Not the Power Pole but the bigger amp rated connectors. By the way, Power Pole connectors are great but not for joining two batteries. I find uses all the time for the Poles, they are great for replacing cigar lighter type.

Hi Dave,

Yes, I see problems.

Those connectors are undoubtedly too small a gauge to carry the charging and dis-charging current to and from the battery. Look at the cables on the battery in the camper and the cables between the batteries should be a least that heavy a gauge with connectors to match. Probably 8 or 6.

Next the battery you add should be a match to the one in the camper. Ideally they should have been purchased together as a matched set. Also ideally they should be setting right next to each other keeping the cables tying them together as short as possible.

I'm not real good at explaining the why of all this so I suggest get the book MANAGING 12 VOLTS or go to THE 12 VOLT SIDE OF LIFE.

They are both good sources,

Chuck

Thanks for the help, that was the kind of info I needed. Don't have room to put them side by side unless I take the camper battery out of the camper and put it in the bed of the truck also.

Those "lift-gate" connectors are fine!!
They're designed for 4ga wire and rated to 200A... just be sure to use appropriate fuses at each end.

That's what I use to connect my truck & TC. Here's a link to that install.

Granger has a connector used on golf carts, it's high amp, and should be used with battery cable guage wire, fused. I keep the connectors coated with dielectric grease. It is reccomended that the batteries be of the same type and age.

Hi,

This is what is balanced and best for twin twelve volt batteries.



As it often doesn't cost a dime more to do this, I think it is worth the trouble.

If you wish to understand the "why" surf here:

I added a second battery and it is not next the house battery. It is also 18 months newer than tho house battery they have been working just fine. Both are AGM's and 110 amphrs. I used a 4ga. marine grade cable with an Anderson connector. If the the connector that you want to use takes a large enough cable then why not use it.
