Can Battery that Powers Trailer Jack be Stored in Enclosed Trailer

Question:

I have question about installing a powered A-Frame jack on my enclosed snowmobile trailer. I know I would need a battery and I already have a good deep cycle marine battery. I am wondering can I install the battery in the trailer instead of on the A-Frame ? I dont want it out in elements and also subject to theft. Also my trailer already has one of those small enclosed batteries on the wall inside which is to activate the emergency electric brakes I believe if becomes disconnected while towing - I have tandem electric brakes. Can I use the wiring already going to that battery inside and replace that small battery altogether with my deep cycle battery ? - or would they be able to be hooked up in tandem etc... ? Or do I need to run completely separate wires/connections to the deep cycle battery inside. I assume I could not charge the deep cycle from the truck 7 pole connection - is that correct? I would plan to simply keep a battery tender on the deep cycle inside while not in use - I have a 120 Volt connection inside that I run a heavy duty extension cord to via exterior plug in. Thanks in advance for any recommendations.

Everything you are wanting to do is possible. You can store the battery in your trailer, you can run your breakaway system off of the deep cycle battery, you can run the wiring you have now for the breakaway battery to the deep cycle battery, and you can charge the battery through the connection you mentioned.

For a 100 ah deep cycle battery we have the Bright Way part # BRW94FR.
