I'm looking for a way to run the A/C on batteries while boondocking. While generators are a good, lower cost solution, my preference is to use batteries. I have a Dometic Penguin II 13,500 BTU with an Micro-Air Easy Start. I plan to size the battery(ies) to provide 10 minutes of cooling each hour for 6 hours at night. The A/C requires: 1728 watts = 14.4 amps x 120v (Micro-Air says 1600 watts https://www.microair.net/pages/dometic-faqs) 1728 watts / 12v = 144 amps, 80% depth of discharge = 180Ah. So 200Ah LiFePO4 battery. To ensure that the external battery only powers the A/C, and doesn't charge the AGM trailer batteries or power anything else, I would flip off the breakers in the Power Control Center for the Charger, Refrigerator and Microwave/outlets. Leaving on only the Main and A/C breakers. Any safety, performance or other concerns with this? Are there any show stoppers for doing it? The battery would be recharged separately from the trailer.

The Oliver is working out great! We're very pleased with the trailer and customer support we've received from Jason, Richie, and Rodney at Oliver.

Thanks for suggesting Kissimmee Prairie Preserve State Park, Mainiac. We visited there 3 weeks ago while kayaking in FL. It was beautiful!

Greetings from Neil & Marybeth in Harrisburg, PA. We're really excited! Our Oliver Elite II, Hull #406, starts production this week! We have some short shakedown outings planned for December, and an extended trip to FL in Feb/Mar to escape the cold winter doldrums. Our tow vehicle is a Toyota Tundra CrewMax 5.7L V8. We enjoy scuba diving, paddling, hiking, and soon traveling in our Ollie. Our plan is to explore our beautiful country before we decide where to settle down in retirement. Many thanks for the wealth of information that's posted in the forums. It was very helpful as we planned our Ollie. Hopefully we can meet some of you when we attend the Ollie Rally in May.
