Breakaway Switch and Battery

[ALANSD]

just caught up with this thread as I was thinking about going to a lawn mower type battery in a plastic box in where my old bigger battery was. I won't used it for much other than the breakway.
Cam someone explain the storage battery, brake disconnect stuff to me? I have no idea what all that means. New trailer guy....old trailer....duh???

Wingfoot wrote "shorter than safety chains" regarding length of breakaway switch cable. I read on this forum, I think, the breakaway switch cable must be longer so you retain control of the trailer even when it falls onto the safety chains. Only if the safety chains break would you want the "emergency brakes" to engage, because you have lost control of your trailer and don't want it to hurtle into other vehicles.

Does anyone remember where this discussion was posted on the forum?

Thanks,

All,
What if the break away switch also fired a flasher relay on the trailer's lights' circuits? Great that the brakes may safely bring down a loose trailer, but if it is dark and there's a car a thousand yards behind you when you lose the trailer at night . . .

Or, is it possible this circuit already exists and we sure don't want to hear a lot of people experienced in how it worked out for them, eh?

But could we do something like this for our trailers?
