Though these Chin batterries are tempting especially from the price point of view https://amzn.to/3KNvYNT
A thousand bucks cheaper along with have bluetooth is certainly tempting. But, I’m still leaning toward the Dakotas since they are U.S. based and may have better customer service and a better warranty.
I thought about a single battery. I definitely would’ve gone that route for all the reasons Mike on Bianka mentions.
The only reason I didn’t was the self-imposed constraint of wanting to do work myself while needing to minimize weight that I handled. Simpler is better, and the batteries that Mark pointed out do look impressive.
The one thing (I think) that might need to be checked is to make sure that the power management systems built into whatever batteries are selected and the external charging system both play nicely with each other.
One of the reasons I stuck with the charger (Delta-Q) and batteries (Battleborn) recommended by ElectricYacht was lack of stomach on my part for delving into those questions.

if you decide to also consider Torqeedo batteries they pack a lot of energy for their weight. However, having purchased 2x24 V I would recommend against them because you are also purchasing a proprietary NMEA2000 communication protocol using a CAN-BUS port but unless you have a Torqeedo gateway (not yet on the market) you can’t make use of this ‘feature’. In hindsight I should have given serious thought to the Battleborn. They appear to be more flexible.
The Dakota and Epoch both have an 11 year warranty but having a local company may make warranty issues easier to deal with. The Epoch will allow charging down to -20 while the Dakota says don’t charge below 32 degrees.
I was not able to find a review of the bigger Dakota batteries but I did find this on a 23 ah Dakota
The Epoch battery also looks interesting. I like the bluetooth availability and the case mounting tabs are handy. Though do not really need the heating function for charging since I won’t be sailing in winter. I’ll be disconnecting the battery when I pull the boat for the winter.
The Dakota also comes with a battery charger. Its small amp wise but, I planned to have my current 48 volt Zivan NG-1 chargers converted to a Lithium profile. But, having a backup is always a good idea and FREE is good.
I still have a few months before I need to decide and who knows what might come on the market by then.
