I bought these brand new for $350 each. I've had these batteries for about 2yrs (they are expected to last at least 10 yrs with 3000 - 5000 cycle life). I have never used them. I put them on the charger occasionally, they haven't needed even a maintenance charge so far. These batteries are in a whole other class from traditional batteries. They are the highest rated battery I could find. Highly regarded on fishing forums.
They are very light. Especially compared to lead. Unlike lead batteries these will provide the same voltage from 100% charge down to around 10%. These batteries have their longest lifespan if you don't discharge below 20%-30%. You can monitor the battery level easily with Bluetooth with a simple phone app.
They come with the handles I have added. They also have rubber padding on the bottom that I added. It's easier on the battery case and quiet in the boat. Also if you buy both batteries you can have the Anderson connector 24v wiring connector for battery connection.
$150 each or $275 for both
