Interesting...

 

Looks like they use the well proven JBD BMS, although not much mention if all the batteries include the Bluetooth dongle which is critical to configure it and monitor cell voltages.

 

They do however use cylindrical cells which have a higher discharge current, although this will be limited by the BMS's peak current capabilities.

 

Most Lifepo4 batteries use four large prismatic cells in series which gives better energy density but a lower peak discharge current which isn't usually an issue for leisure batteries on boats.

Bear in mind that the large number of connections (and the way they're done) with cylindrical cells makes the quality of manufacture/joints (spot-welded and/or soldered) much more critical than with prismatic cells. This is fine for manufacturers with well-established high-volume production lines (e.g. Tesla) but not so good for small-volume suppliers -- especially packs built in China, which I assume these aren't but it's not clear from the website.
