I am installing an alarm system and LED lights in my 6x12 cargo trailer. I have a battery for the trailer brakes that gets charged when hooked up to the truck. I don't want to use this battery for the alarm and lights, I am installing another battery inside the trailer just for that. I want to charge the inside battery when it's hooked up to the truck, and only use the inside battery when unhooked. So my question is:
Do I need to install a battery isolator on the trailer? If so, what amperage is acceptable?
Or can I use a 40amp Automotive Relay to isolate the inside battery when disconnected from the truck and when the truck is hooked up, it will charge the inside battery also?
I am towing with the wife's 2013 F-150 right now and will be using the Ranger when Ford comes out with the TBC.
Thanks!
