Bring your single-, double-, or triple-axle trailer to a stop should it become disconnected while towing. Includes a charger that maintains battery so you're always ready for an emergency and U-bolts so you can mount it to your trailer jack.


Features:

  • Makes sure your trailer safely stops if it separates from your vehicle
    • When the pin gets pulled from the switch, a signal is shot back to your trailer brakes to activate
  • Automatically charges battery with the built-in charger when connected to your vehicle
  • Mounts to the outside of your trailer's frame or to your jack post
    • Side-loading case provides easy access to battery
    • Mounts to jack post with included U-bolts or to trailer frame with self-tapping screws (sold separately)
  • Protects battery from rain and debris with durable, plastic case
    • Lid can be secured with padlock (sold separately) to deter battery theft
    • Rubber O-ring helps keep water out of the box
  • Includes breakaway switch, battery box, wiring, and a 5-amp hour, lead-acid battery
  • Department of Transportation (DOT) compliant


Specs:

  • Application: single-, tandem-, and triple-axle trailer with electric brakes
  • Battery:
    • Voltage: 12V
    • Type: sealed lead acid
    • Capacity: 5 amp-hours
  • Charger lead wire length: 47"
  • Breakaway cable length: 48"
  • Breakaway switch:
    • Dimensions: 4-3/8" long x 1-1/2" wide
    • Lead wire length: 12"
  • Battery box dimensions: 5" long x 5-1/4" wide x 3-3/8" tall
  • 1-Year limited warranty


Note: A breakaway system is required by law in most states for trailers that are equipped with electric brakes and have a GTW of at least 3,000 lbs.


Quick Tips:

  • When you store your trailer, be sure to keep the pin plugged into the breakaway switch. If the pin's removed for an extended period of time, dirt and moisture can get into the switch and cause corrosion that could keep it from activating when you need it.
  • A breakaway system needs to be able to apply the trailer brakes fully for at least 15 minutes. In general, the heavier your trailer, the higher amperage battery you'll need for the breakaway.

Good breakaway switch, but no way to know whether the battery is fully charged.

The battery can be tested for 14Vh. During the operation, the system provides a trickle charge to maintain battery voltage. When battery voltage is under 6V, the tester circuit will not have power and the red or green light on the switch will not activate, indicating that the battery is dead. I recommend using a break away kit with a battery tester like item # 20099.



by:

The u-bolts worked great for mounting the battery box on an electric tongue jack. I ended up heat shrinking the leads coming out and then siliconed the hole so no water could get in. I was not able to fully test the break away switch and stop the trailer with the battery but feel confident in the product.



by:

I also bought a new plug with attached junction box. The battery and charger were straight forward to wire. The only problem I had was that my old trailer wire colors did not match the new plug colors. Once I sorted out my wires everything worked well. I think it is a good battery kit



by:

HAD TO DRILL NEW HOLES BUT OTHERWISE INSTALL WAS EASY JUST CUT AND CRIMP WIRES USED HEAT SHRINK AND SEAL BUTT CONNECTORS.



by:

This was a replacement for an aging unit. Installation was straightforward. I hope to never need the unit as it would only come in to use in the event of a loose trailer so I cannot comment on it's function.



by:

Easiest and best upgrade to my boat trailer brakes. Would recommend to anyone.



by:

Good web site, good value, great instructional videos. Quick delivery!
Wish it had a battery stus indicator. Only one that fit the jack.
