Li-ion batteries capacity on the new R-25 OB

[Seaginger]

When ordering my new boat, I opted in to the Lithium-Ion package. By reading through the spec sheets and descriptions, I had learned that the package would consist of six 100 AH house batteries for the total nominal capacity of 600 AH.
However, my 2024 Ranger Tugs R-25 arrived with two x 280 AH batteries instead, for the total capacity of 560 AH. I was not made aware by the dealer that such substitute would be made. Can someone please advise if the 40 AH reduction of the total battery capacity was justified or is it still a downgrade? I can see the obvious benefit of the total size and weight reduction (~61 lb) of the two 280 AH batteries compared to six 100 AH ones. But are there any other benefits? Thank you!

Upgrade!!! We have same on our new R27LE.

The weight reduction and added storage is totally worth the 40ah. Either way you wont use the AC for very long without shore power. I have a small portable 30A/3.5kw generator we use when overnighting on the hook to power the boat as if we are on shore power.

weight is a major factor in these boats. sounds like a good upgrade!

The original design from RT was (6) 100ah G31 size batteries. 6 batteries take up a lot of space. Dakota recently came out with a 280ah battery in a G31 foot-print. This gives back a ton of space for storage and is well worth the change. It's also 4 less batteries to cable in making the install cleaner. The 280ah Dakota batteries I believe also have an internal thermal blanket allowing them to be used (charged) in freezing temperatures. The 100ah batteries are not to be charged below freezing temp's. Probably not a concern for most boaters.

Thank you all for your prompt replies!
Good to know all pros and cons.. (looks like no really any "cons" in this case) 🙂

Thank you, Martin! Your opinion is always solid and justified. Your Youtube channel was one of my first sources of information about RTs. Appreciate, it's very helpful!
