We had to replace one shortly after receiving it that had a finicky Bluetooth module and didn't like to connect. The replacement was super fast and easy.
I plan to pull our remaining AGM batteries out, they're not worth the weight and space when these work so well.
Edit- I bought mine through their ebay site.
Community Reviews
This ECO-WORTHY 12V 280Ah LiFePO4 battery is drawing attention for its very low price, Bluetooth monitoring, and strong value for non-critical solar, RV, and backup setups. The battery has been used successfully in cold weather, in RV and bus conversions, and in long-running solar and UPS-style projects, with some units still working well after years of use. The main cautions are checkout glitches, extra fees or taxes, and occasional Bluetooth or shipping issues. It is a capable budget battery if you are prepared to verify the final total and wiring details.
Bluetooth monitoring can help track battery status during off-grid or winter RV use.
Overkill app management can work for at least some units after purchase and setup.
Some buyers report fast shipping from a Houston warehouse after ordering.
Cold-weather operation can work down to about -30°F for winter RV or bus conversions.
PayPal $15 off promotions can fail to apply at checkout even when the coupon appears.
Checkout pricing can jump to $300+ unless coupons or deal steps apply correctly.
Bluetooth monitoring can eventually disappear and may require running the batteries down until the BMS trips.
Some orders can arrive with physical issues like the top separated from the case and visible internals.

My delta 2 is connected to one solar panel and powering our garage freezer.
The panel is giving me 480 watts on a good day and by noon, it's already full.

Mine isn't sealed and I can see the guts so guess it's going back as a return. Also has some minor damage to the outside.
This is only 12v and on the video is 51.2v
It not depend on the boat size, it depend on your electric motor generate how much watt. For example, if your motor generate 500 watts, it would run your motor 7 hours for 1 battery.
