Greetings all,
While we've purchased a 2022 Imagine 2500RL (with solar and 12v refrigerator), we have not brought it home yet. There is this little problem of the F-150 not being delivered yet...showing 25FEB22 estimated delivery... I hope to get the trailer home (it's 60 miles away) sometime in April, depending on road conditions.
Anyway, I will convert it to lithium batteries, 2 each Renogy 100 amp-hr. I've ordered the WF-8955LIS-MBA switchable converter, and plan to order the Renogy 20amp DC-DC charger. The F-150's circuit for this is fused at 30 amps, so the 20amp charger seems appropriate.
However, these words are in the 2022 F-150 owner's manual:
The trailer receives power from the vehicle
trailer connector battery lead when the
following occurs:
• Your vehicle is in accessory mode or
switched on.
• The trailer wiring connector is free of
corrosion or other damage.
• The vehicle battery is not low.
• When the trailer has a battery:
• The trailer battery voltage is within
5 volts of the vehicle battery
voltage.
• When you have the trailer battery
properly connected.
The truck has to "see" the trailer's batteries "through" the Renogy charger. Does anyone have this same truck/charger combination, and does it work? I've thought that if it doesn't, I will add a resistor between the input to output, one of sufficiently high resistance to be irrelevant during charging, but to allow the truck to see the trailer's battery voltage.
Thanks -
UPDATE 2MAY22:
I completed the electrical modifications to the trailer, and tested the Renogy DC-DC charger. It did not work at first...but, I found on a F150 forum that one might need to press the brake once to activate the charge circuit in the 7 pin, and that did activate it in a subsequent test. In any case, the truck did "see" the TT battery system. BTW - I did not run a separate line from the Renogy to the ignition. I simply ran a wire from the input + terminal to the "trigger" input (Renogy calls this the "D+ Ignition pin). If one had a 7 pin battery that stayed hot when the ignition was off, this method would not be advisable...
