Question:

What size battery should I get to power short use items like an electric trailer dolly or electric tongue jack? I just bought my 7x14 enclosed trailer and Ive got some gadgetsinch on there to help me out. Like tongue jack and dolly for moving it around. I use a small lawnmower battery, but it runs down very quick. I also plan on installing a solar charger for this battery. I want to make sure I have enough battery, so Id rather have an over estimate than under. Thanks

If you are wanting the absolute most battery the best solution is the Power Sonic RV Lithium Battery part # PS74FR which is a 300 amp hour lithium battery that will last a really long time. But it's not cheap at all...

A standard deep cycle battery like the 250 amp hour part # BRW64FR costs a lot less but would still last a long time as well.
