I’m hoping to be able to charge the batteries on a bass fishing boat with my new F-150 Lightning Lariat. I would like to be able to charge while traveling/towing and when parked.
Water Boat Watercraft Vehicle Green

The boat will have a Pure Outboard System with 2 Battery Packs.
The 2-Battery System Includes:
25kW electric outboard motor with power tilt/trim (112 lbs)​
One or more 8.85 kWh battery packs (118 lbs each)​
Mobile charger connects to 120V & 240V outlets (24 lbs)​
Bluetooth-enabled throttle​
Connecting power cables, throttle cable and throttle mounting bracket​
Pure Watercraft’s standard prop (16″)​

According to a reply from a Pure Watercraft customer relations person, the battery charger will operate with a 120V outlet, so long as it supplies 15A, or any 208-240V outlet with 35A or more. The person continued saying, “it sounds to me like the 240V options in your truck will not have enough amperage to effectively charge up one of our batteries, but the 120V options you have would.”

Also attached the diagram that displays the three types of plugs which they can send me along with my order, as well as the electrical requirements for each. “For your dual battery order, I would recommend having access to a larger 208-240V 50A outlet where you'll be storing your boat (if you would like rapid recharging). Otherwise, you can expect one of these standard 120V outlets to recharge one of your batteries from half to full in 4.5 hours.”

Thanks for any input.

They are correct. You will be able to use the 120v charger but your truck can only deliver 30A at 240v.

It seems strange that the charger would not accept a lower amperage as 20-30A at 240 V is far more energy than 15A @ 120V.

I suppose ideal would be to charge both truck and boat from home/overnight stop, charge truck near boat launch while you are out fishing, and then charge up boat as you drive it from one launch to another. Just be sure to account for the efficiency loss transferring energy from one battery to another. There is another thread on here talking about using Lightning to charge a battery electric plane that may be informative for your use case.

Thanks, I PM the student to find out more. Very exciting times.
