Question:
If the safety pin on the trailer is removed while the trailer is parked, will that drain the batteries quickly?

It sure will. Per DOT regulations, a properly functioning breakaway system should be able to hold the trailer brakes engaged for a minimum of 15 minutes. Past that point, the battery(s) would wear down pretty quickly if you're speaking of a small 5 amp battery like # TK2023.
This is why some folks will wire the breakaway system into a larger battery that's also used for a powered trailer winch or jack, which isn't a great idea if you've used your winch or jack quite a bit and the battery has become weak.
We offer a 10A system from Bright Way group that includes a 2A charger, part # 3802311 that is a huge upgrade over a typical trailer break away kit. If you're looking to upgrade, that's what I'd recommend. I've linked you to a product demonstration video that you can check out if you wish.
