Permanent mount battery tender

[CrazyCooter]

i suppose this could also work

You could use that plug if you had one but why? It would encourage someone to plug it into the 4way on the bumper?

It will charge both since they are connected in parallel.

Thank you. That is what I thought but wanted to make sure.

Yes, that's even better. Allows you to use your float/trickle charger with the ends it came with at other times.

I do that sort of thing as well - it's one reason I have tubs full of wiring bits and a couple of cases with various terminals and fittings.

And with these in my truck at all times, I can hook almost anything to anything - the one adapts the trailer plug to a 12v, another plugs into a 12v and give you two 12v outlets plus built-in USB charger........
I could run 4 things that plug into 12v outlets at one time if I needed to with my bed mounted 12v outlet, the trailer plug and these adapters, and the 12v outlet in the cab.

Same thing for me.....I have a bag of adapters SAE, Cig lighter, Andersen, etc..... This way I can charge w/ tender, solar, cooler in the bed, HAM radio......

I hooked up a MagCode magnetic connector with a Battery Tender charger. Simple low amperage fuse (5A). Small hole in the plastic cowl and it looks pretty clean and cheap enough to replace if I had to.

It's hot all the time, and I've used it to power a small compressor (the sort like AMC and GM used for their self-leveling air shocks) and other stuff.

No to the flat 4-way.
The 4 way flat plug only has
ground,
left turn,
right turn
tail
- not power.


Buy a cord end from Amazon.
Wire this onto the charger's battery ends -

You can also get this to turn that trailer plug into a 12v outlet -

That way I can plug any 12v accessory into it.

so pin 4, aux, would be 12+ correct?

Yes, looking at the truck's connector 4 is 12v+ and is at about the 1:30 position.
#1 is ground and is 180 degrees from the 12v spot 4 - in other words at the 7:00 position.

Be careful as these are 7 blade -
there's also a 7 "pin" that has round pins and corresponding round holes. (Those must be common in Australia?) and are a bit different.

do you happen to know what wire gauge the jeep is using on the 30a 12v+ wire? I would assume 10. I dont think my battery charger wires will fit in the plug so I wil have to splice them to a smaller gauge wire. I have 6, 8, 10, and 12 available.

Holy cow, how big are your battery charger wires? How big is your charger?
6, 8, 10 and 12 are much bigger wires than what your battery charger has unless it's got boost capability.
A battery tender or "minder" or "float charger" won't have leads any bigger than 16 gauge, maybe only 18 gauge.
My 1500mA tender has 18 gauge leads to the battery. (that's 1.5 amps, most tenders are that or smaller)

Even my 20 amp AGM charger doesn't have leads as big as 14 gauge.
You'd be amazed as far as what size wires fit into a trailer plug.....
There's no way in #@$@# that 6, 8, 10 or 12 are smaller wires, and those are a gross over-kill for battery tender wires.

I think theyre just oversize. No idea why. Theyre 6 or 4 ga. The charger only pushes 15a max. It must be that company buys in bulk…. kinda weird. I was thinking 10ga. Again because i have a lot of it lying around….. And figured thats what the vehicle side size would be.

Pictures would clarify the issue…

This is all I ever use for my ATVs and hooked it up permanently under my mom's hood, she's never had a problem with it yet going on 3 years.

This is the kind of ingenuity I love to see here.

 

[trilifter7]

I just ordered the NOCO genius 5 to permanently mount under the hood. is 5A too big or should I be using the 2A one?

If you like the idea of connecting to the trailer plug leads, but want something easier to break away from (and also use to power devices out on the road), take a look at what I did here. It's a marine 12v outlet thats tapped into the hot wiring for the trailer connector. Works great to maintain a charge, but also works great to power other things if you need to. I've used this socket to power campsite equipment or chargers as well as using it to maintain the battery at home.

I do like the 7-pin to 12v adapters like @ShadowsPapa mentioned, I just don't like how big they are and that they clip in (important if you worry about accidentally driving off without unhooking it). Just the socket instead is pretty clean and will pop right out if you drive away. Bonus points for not having to keep an adapter on-hand.
