Re: [electricboats] Need 48v 200A for Electrictyacht 10kW motor, should 1 get 4 x NPP12V 200Ah Li or 2 Dakota 48V 96Ah?

That should say "are not apples to apples"

They are almost twice the cost of Chinese brands. The other link as near as I can tell is a low cost Chinese brand, this one apparently lower than other (warning sign) and has very few reviews (also a warning sign but not necessarily bad - everyone has to start somewhere). There is a bottom tier of low cost Chinese battery reseller companies that perennially rebrand and grow like weeds and have almost zero quality control and usually are seeded with a crop of fake reviews. The more established ones have more reviews, have been around longer, and tend to all track one another pretty closely in price. You can often find reviews on the Will Prowse YouTube channel for some of them.

Eg4 from signature solar is established as a pretty reliable Chinese import brand with great us based support they have a really good price on their 48v 100ah ABS style housing batteries right now. If you want the best moned and made in USA go with Dakota or battleborn, but if you are more cost conscious look at eg4 and the raft of similar copycats (litime/amperetime).
