  • 22 amps max current
  • Only the very BIGGEST truck to trailer cable will pass more current than that
  • Set the charger at the voltage YOU dial in and FORGET what factory idiots tell the alternator to do
  • CORRECTED VOLTAGE only goes to the trailer
  • The tow vehicle stays at the factory idiot setting
  • Want 14.40 EXACTLY for Lifeline batteries -- you got it?
  • Need higher or lower set voltage...you got it.

Put some Panasonic or Nichicon caps on there, replace the tiny screw terminals with soldered on wire and anderson connectors, replace the tiny trim pots with genuine Bourns multi-turn panel mount pots and what else?

...Look up an ad for a Sure Power booster and bucker and have a heart attack at the price.

Finding a ventilated cover would be the first thing on my list.

Then chop off a pair of of these connectors. 12 gauge wire from booster to terminal block. Six gauge wires running to the rear trailer connector.

Even better would be a 20-amp auto-reset circuit breaker.

How much does a mounted set of solar panels cost? Not a controller, call it adding to the existing array on the roof? Twenty amps worth? Can they be on-call 24/7?

There is a time and place for everything and a 3-hour boondocking move could add 60 amp hours. 5 hours 100 amp hours.

Does it self limit the current? My battery would absorb way over 22 amps at setting 14.4 volts.

Yep. Big time.

It takes huge circular mil cable to decrease PERCENTAGE of voltage drop. With say 13.9 vdc traveling 40' a person would need 0000

With a Delta T of 1.7 volts, a person will still need six gauge wire to approach a 20 ampere figure.

But newer vehicles IGOR voltage control inside the ECU makes the idea of tow charging ridiculous. These are the folks who cannot figure out ECU control with a "tow package" is an OXYMORON. Authentic design integration from a cluster of fiefdoms.

Reminds me of down here. Being passed by an older car running an emergency spare tire on the front left. Hit the brakes at 75 mph and veer into oncoming traffic. It's institutionalized -- Washington DC operates this way...

If you believe that device is capable of anything NEAR 2200W I have a bridge for sale. Mount that thing in a box with about a 4" muffin fan blowing across both the top and the bottom. Replacing the caps with "name brand" ones is a good suggestion.

If you do mount it in a box, I would buy one of those cheap Volt/Amp meters so you can get a quick looks see at what is going on.

Auto companies are not about to mess with their "smart charging" strategies. They get an extra 0.1 or 0.2 MPG by keeping the charging voltage AT THE VEHICLE BATTERY as low as possible !

Just mount your gizmo close to the battery that is going to be charged. No worries about voltgae drap as long as it is above the minimum.

IT'S A TOWING PACKAGE ! NOT AN AUXILIARY BATTERY CHARGING PACKAGE !

The fact that B+ is even on the 7 pin connector is "historical". Sadly, very few people really understand this !

Love to respond but a gaggle of stupidity gets in the way

I still don't know if my low battery will burn the thing up.
Or will the current be internally limited to 22 amps?
I honestly think my truck will provide up to 40 amps if the connection is right.
10 volt minimum input should draw out plenty of juice.

My new truck ecu seems to prefer operating at 14.3 volts, indicated by two dmms. I haven't measured the voltage at the Bargman however.
