R25OB Delivery Experience

We are waiting for our R25 for a July delivery. I watched this video 3 times. We are so dang excited! Keep posting, let us know what you think. Thanks for the video.
 
Congrats with the new boat Jim and Lisa! Looking forward to learning about your new adventures with R-25OB!
And what a great video, thanks for sharing! I completely agree, Factory Delivery experience is absolutely imperative to get quickly up to speed on new boat. All the vids we took from ours still serve us as a reference when we are in doubt.
 
Jim & Lisa:

What a wonderful and informative posting of the video you've made available to us. Thank you very much.

If there's one constructive comment I'd like to make here, it's this....

As your boat has the Lithium ion battery option, this should be made clear in the video so that others don't see the batteries in the cockpit's center storage area as a stock item, along with the battery meter fwd of the fresh water meter. I certainly was aware of your Lithium ion battery option, but when I saw the battery meter, thought that it was a stock item (and got very excited thinking I would have the meter on my new R25/OB later on in 2022), but subsequently after enquiring about it, found it was not and was part of the Lithium ion battery option.

As an aside..... Maybe RT could use your video (with your permission) as a link in their "Build your Boat" web site as a testimonial for the "Factory Experience". 🙂
 
Thanks for sharing. Great video. I may have missed it in the video, but what is the round instrument above the autopilot at the helm?

I am an East Coaster that still works sometimes so the factory delivery isn't in the cards for me so thanks for the video.

Overall, I was surprised that the house lithium bank is literally charged with just an ACR via the cranking battery bank as a pathway to the alternator. I would have thought a DC-DC Charger would have been provided. But then again the amperage will find it's way and the lithium will eat it up, I just always thought it would also cannibalize the AGM batteries at the same time. And wouldn't the ACR close when the cranking batteries are being charged therefore connecting the AGM and Lithium into the same bank and vis versa with the lithium charger? Maybe I misunderstood, nevertheless, lithium is a great option on these boats.

The LE has a DC to DC charger. It's an Abso 50 amp DC to DC charger. It takes 2 inputs, one comes from solar, the other comes from the engine to thruster ACR (on the thruster side). The single output goes the LFP battery bank.

I have a drawing that illustrates all this that I can share.
https://www.letsgochannelsurfing.com/luxury-edition-lithium

Engine turns on, outputs to the engine battery. The ACR sees the charge voltage and closes which parallels the engine and thruster bank. There's another device there (Digital voltage sensing relay), that senses a charge voltage. If present, it closes, if not, it opens. (Otherwise, the DC to DC charger would always run from the thruster bank to the house bank, with or without a charge voltage).

The LiFEPo4 bank does not get charged directly from the engine.
 
Thanks so much for posting that. My boat has that same Abso DC to DC charger and everything you show on the diagram plus a second charger and some other items, except my boat has two engine outputs so there is no ACR connecting the engine and thruster battery. They each get their own feed and the thruster ultimates feeds the DCDC changer. I get how it works. But I swore that I watched the video posted and that’s not what was described. I will have to rewatch it. Good to on didn’t change the design.
 
Also the Abso DCDC changer actually pulls a load from the agm feeding it for 3 minutes and then checks to confirm it has a charge source. So I can see the VSR saving a 50 amp load on the thruster battery for a brief time, but I don’t think it’s necessary, not to mention ASR’s are also a bottleneck in charging systems. I feel like lithiums aren’t ready for outboards yet, it’s too bad that outboards don’t have smarter alternators that you can program for a lithium charge and then use a DCDC charger to handle charging the cranking batts from the lithium.

No prob! I get asked a lot about the LE, with its LFP setup. I'm looking to put out a video all about the LE electrical, and compare that to the NW edition.

Looking forward to this.... when ?

I'm seriously looking at using the R25/OB LE with the Lithium-ion battery option for my PNW adventures, but have the concern it's A/C heat mode creates a lot of moisture inside the boat. Now trying to figure out a solution for this.

At this time the R25/OB LE Edition is the only model RT will agree to install the Lithium-ion batteries. 🙁

I've already started putting material together for the electrical overview video. I'm working on drawings and such to best illustrate how it all works. I'm also working on getting onboard an LE, so I can get some photographs of their LFP installation. I have a few pics others have sent me, but I need to crawl around in one. Hopefully, sometime before the end of March we'll have a video to publish about this.

I would also note, it is possible to upgrade to LFP after the boat's been purchased (after-market upgrade). The factory builds boats. If every boat were 'custom', it would take them a lot longer to build them. The current wait for a boat today is a year, I'm told.

Since we boat in the Pacific Northwest, without any plans to boat in a hot climate, personally, I wouldn't want the LE for LFP if it meant I had to get the air conditioner. We use our Webasto diesel heater a lot.

As far as moisture in the boat goes, sleeping on the boat with 3 dogs and 3 adults creates more than enough moisture of its own. We've found 2 ways to deal with this.

1) Vacuum Squeegie. (Start at the 11:20 mark)

2) Get a small portable USB powered fan. Stick it on the port side, pointing towards the front window, put it on low, and let it run all night circulating air.
