View Full Version : battery brainstorm ahead.........

my bumper pull travel trailer has a deep cycle battery mounted to the tongue.....
when it's hooked up to the truck, the truck's alternator charges that battery.

I am wanting to replace the deep cycle marine battery on my PS190 (the battery is still good, but not dependable)

why couldn't I mount it (old battery) into a battery box to the tongue on my boat trailer and wire it the same way? always having a charged battery available. I've got enough tongue room to mount a battery box with 4 inch U-bolts, and cut a piece of pressure treated lumber to place in the bottom of the box (with holes drilled in the lumber to accomidate the U-bolts coming up through the bottom of the battery box)

I already carry a jumper pack, but dang, I'm really figuringhttp://i10.photobucket.com/albums/a112/milkmania/stuff.gif

Not sure if there would truly be a need for it???? Seems like it may just be over kill :confused:

I think that's a pretty cool idea especially if you take your boat on long weekend or trips.

two hot batteries at the lake is not overkill, it might be the thing that makes or breaks a good weekend

I've got to study it a little more....not sure if the travel trailer wiring goes through the inverter then to the battery....

and I do know from experience that when the travel trailer is hook to the truck, and I'm drawing voltage inside the travel trailer, it will drain both batteries...

so, I could install a toggle switch in the truck to break the connection once I got to the lake, or at least always remember to unplug the trailer.

You could also add the second battery under the hood of your burban and you would have it with you all the time.

I agree with having 2 batteries with you on a trip, but I would be worried someone would steal it. I have had the guide pads stolen off my trailer once, and if there was $100 in battery equipment it would probably walk away pretty quick.

I guess I should have been more specific in my first post. If it could be really secured and not taken from the trailer.

Why not mount a second battery in the boat? That way you have it on the water when you need it. I'm sure it would walk away at my ramp.

I'm just thinking with a "good" battery in the boat, I shouldn't need the other battery, but have it there for when I do bonehead things.

at this point, I have a Continental Deep cycle, and it's cranking the 351 slowly, even after using the floating battery charger......the battery is only 1 and 1/2 years old.:(

Just a thought on your slow cranking issue . . . I had a slow cranking issue (especially when hot) with my boat last year. I read on another site awhile ago that deep cycle batteries should not be used as our starting batteries. We are starting car engines after all. I had a deep cycle that was only 2 years old. I put in a regular automotive starting battery, and my slow cranking issue went away. Worked for me . . . good luck.

Also, not having enough current available when cranking is a really bad thing for the starter and solenoid.

Be careful about wire size with current draw to/from that battery for charging and discharge.
