Lawn tractor battery for TT

I'm at 670 lbs on my TT tongue weight. Ive removed one LP tank, moved the spare tire To the bumper n now replacing the TT battery with a lawn tractor battery. I only need the battery for the electric jack n break away brakes. I'm trying to reduce weight by 100 lbs.

Would a Lawn tractor battery work??

It would work. Personaly I would look at a closed cell battery, one simular to what is use for emergency lighting.

The battery would work for the break-away braking system, but I'm not sure about the electric jack when using the lawn tractor battery only. If you always were plugged in to the TV and the TV running, then lawn tractor battery shouldn't be a problem.

I would suggest buying a specific trailer brake battery, maybe a few dollars more. While it may not power the jack as mentioned, it may last longer since it is designed to work in that situation to power the brakes.

As for reducing the tw, what Tv do you have and how much passengers and cargo are in the tv? REDUCING the tw to much can and will induce sway!!! So be very careful you do not reach that fine line. You want between 12-15% tw. It depends on your particular trailer as some are fine with a lower tw%, while other trailers like a higher tw%.

Good luck!

I know your heavy on the tounge weight, but how are you overall? I ask because if your underweight you might be able to add water to your fresh water tank to even it out a bit.
Also I am assuming you have a WDH.

Thanks guys. I'll brain storm this. I'll think about adding water to my fresh water tank to even it out a bit.

I had the same problem on my 154bh, tw was around 500# and by relocating the battery in the back storage (now an AGM) it's right at 14% instead of 17%


I was looking at buying a small battery, but I would only remove 35#, but relocating I added 40# to the back and removed 40# from the front!
