Accessory Power Consumption

[John Becker]

I’m interested in learning how many watts the F150 Lighting consumes to run various accessories. For example:

• How many watts does the A/C consume at maximum power and on the lowest setting?
• What about cabin heat?
• Heated seats?
• Exterior lighting (headlights/taillights)?
• Interior lighting?
• Displays?
• Rear window defogger?
• Windshield wipers?
• Radio?
• When the truck is simply “on”?
• Vampire losses when the truck is “off”?

The list goes on... Can somebody point me to a Ford technical bulletin or another thread to help me answer these questions?

No such source exists.

The best available information is in the F-150 Lightning Modifier's Guide; Section 2: Electrical, pages 2-8 and 2-9.

This is interesting on page 7:
Vehicle Storage — Electrical NOTICE: If your vehicle is to be stored for 30 days or longer, the low voltage (trunk) battery negative terminal must be disconnected. Failure to do this could damage the battery.
NOTE: Extended storage time which results in the discharge of the low and/or high voltage batteries, may result in the setting of Diagnostic Trouble Codes (DTCs) and/or a no-start condition. To maintain the high voltage battery, once a month the vehicle's high voltage battery should be charged. This will maintain the high voltage battery, but may not be enough to maintain the 12v (low voltage) battery. Additional low voltage battery charging may be required after 60 days. • For BEV Vehicles, the vehicle should be started and driven to maintain high voltage battery charge.
