Battery disconnect switch

Hi,

I'm looking to install a battery disconnect switch on my Laredo 291TG. What brand are you using? Thanks.

DC Disconnect

Great company, BD Batteries - I installed this switch yesterday, stop the trickle discharge on my batts when I'm parked waiting for the next great adventure.

Oh, BTW, Install the switch on the negative (ground) wire directly off the battery bank, no muss, no fuss, no spitz'n spark'n!

Hi Pollockd,
Just want to throw in a word of caution about installing a battery cutoff switch. If you install the switch and forget to set it to the ON position before towing your trailer and (here's the 1:1000000 chance) your trailer somehow uncouples from your truck while you are driving down the highway, the safety brakes will not activate.

Would this stop me from installing a battery cutoff switch...no way! But always remember to set it to the ON position before towing the trailer. Sometimes Stuff does happen!

Good point Steve, or was it April?.... Margo?

Perko or Blue sea make good disconnect switches. I mounted mine inside the front pass through compartment. Wired it so the jack and brake power is always hot. Neither of these draw any power when "off" and it lets me run the jack up and down with the power off.

Our Fuzion has one of these from the factory for battery cut off.

I added another to cut off power to the landing gear and rear stabilizers when camping. Going to add one to our other fiver as it does not have a battery cut off.

The Toyhauler we had prior to the Fuzion also had this switch from the factory as well. Never had a problem.

cut off

Should the amps rating for these swithches be a concern when picking 1 out?

Absolutely!!! You want a switch rated for at least the maximum amps you will draw. In most cases that is at LEAST 50A, since that is what the CB is usually set for. If you have an inverter or other draws, account for those as well. In my case I have an inverter installed so I went with a Blue Sea disconnect switch rated for 300+A continous. Inverter can draw 200A.
