You need to get new battery. Trailer brakeaway emergency brakes depend on it as well as other stuff.

it's pretty expensive. i'd buy them soon or later though.

Are you TOWING the trailer on public roads without a battery?

I hope not.

No working battery means your emergency break away system will not function..

Every state requires a functioning break away system if your trailer is equipped with electric brakes..

If you can afford to buy a "jump start" unit, you CAN afford to at least buy a group 24 battery or heck even a lawn and garden tractor battery.. On utility trailers the break away systems use a $20 5 Ahr or a bit larger gel cell..

Fines will be far more costly than a new battery and other motorists lives are at risk..

jump start is only 40 bucks. Deep cycle is 500$

5Ahr gel cell is $20..

Your "jump start" battery for $40 is a terrible purchase if you are using for only opening the slides..

If you are towing it on PUBLIC ROADS IT MUST HAVE A WORKING BREAK AWAY SYSTEM.. No battery on board = no break away system.

Not only that you mentioned that hooking trailer up to your vehicle blows fuses so I am assuming you tow it without marker/tail lights and not even using the trailer brakes?

Not to mention I don't know where you are buying GC batteries at, you can buy those at Sam's Club or Costco for about $80 per 6V battery or a total investment of $160 for one pair.

There is no excuse for towing your trailer on public roads without having all the proper lighting and braking system in working order..

There is a reason why some states like mine that INSIST on having a annual inspection on trailers.. It ensures folks are at least fixing the stupid simple things like brakes and lights..

it has lights n brakes all r working

Gracious! Where are you trying to buy your batteries?? sounds like you are getting robbed! I have two deep cycle batteries in my little Class A, and didn't pay near that for both of them together! and I can easily run both big slides in an out on just the batteries.

i think/hope he meant trying to power the slide off the 7way is what blows the truck fuse, not just hooking up. I would assume (i know, dangerous to assume) that his lights work just fine off the 7way, and he tested his brakes via brake controller when plugged to 7way.

the important thing missing is EMERGENCY brakes. In the event of a break-away, the battery powers those, as obviously the 7way has broken-away, as others have mentioned. Not trying to attack the OP, just educate him/her so we're all safer.

Your plan is not only economically foolish (Penny-wise and Pound foolish) It is very questionable ethically.

While trailers do not often come unhitched during travel , it does happen. And if that should happen to you you owe it to the people in the car behind you and the others around you to have that very important safety feature working.

It is Legal Negligence. I know if I was the Attorney for the injured parties I'd not only find this conversation for evidence but I'd OWN you and you'd be lucky to escape criminal charges for Criminal Negligence resulting in Bodily Injury or Death.

Get a Battery. Period.

Unless you have a very unique braking set up your brakes are powered by the electric controller through the trailer plug.

If the TT becomes separated from the TV and the plug is disconnected, the separate brake switch cable stays with the TV. This activates the emergency switch and the brakes are now energized by the TT battery and lock up.

That is how it should work, whether it does or not depends on you.

I did stupid mistake jacking up my tongue and destroying the breakaway plunger. I towed it home and had no issues. Campground was 6 miles from house on level roads 25mph.

I believe your converter is going to be working extra hard all the time trying to charge your batteries. I had to replace a convertor and I believe that was the reason.
