Battery jumper box for toad brake

What are the pro's and con's of using a jumper box battery as a power source for a supplemental brake system, to solve the toad's battery from dying?

If you're talking about a separate battery just for the brake in a box, it sounds like a lot of work and weight. How would you keep this battery from running down? I (and most) just run a charge line from the motorhome to keep the toad battery charged.

Nothing like doing it right the first time.

+1 on a charge line ... much cheaper and far superior solution to your issue.

I use a JNC4000 for my braking system (RVI Brake2). It works fine for me and I don't have to worry about another wire from the MH. I just plug it in to a 120vac outlet and charge it every couple of trips.

I agree with dennis4809 just run an extra charge wire. If you use a 7 prong plug there is a spot for one, simple and easy. I bought a device from Brake Buddy that you hook up to your battery, it has a fuse and a diode in it so you dont back feed to the coach. I am sorry I dont have the number for it handy right now, lost info. If you googled it you find it.

A friend used one of those jump starter in his Honda toad for years. He just charged it every night. He said it worked well.

Both my friend and I have using this system for over 50K miles. Just charge it when you get to somewhere with electricity for the night. KISS system. I've used it for other things too as long as I have it with me.

My toad battery must be disconnected when towing. My JNC660 works fine; recharge about every three days. As I understand it, not all jump boxes use a sealed battery and some may have to remain upright.

The brake buddy in my toad works off of the toads electrical system ie power outlet on dash. The battery in the toad is charged up from the towing vehicle charging system as I am driving down the road. The power wire does not go into or through the toads charging system. It goes straight to the battery through a diode so it does not back feed to drain the battery. A staring battery should not be deep cycled that is drained down to much as it will shorten the battery life. Seems to me charging the toads battery as you are going down the road is the easy way to go.

By far the simplest and easiest solution is to just run a wire from pin 4 (the black wire) on your 7-pin trailer connector to the positive terminal on the toad battery. This is the "charging wire" referred to in the posts above. Works like a charm. Been doing this for years and have never had a problem with it or had a toad battery go dead.

I used a "jump box" with my "brake in a box" for 3 or 4 years and finally installed a charge line. The jump box worked just fine while I used it.
