You guys probably already know this, but for clarity: the label identifies the chemistry as LiFePO4 (lithium ferric phosphate) which would be one of the safer lithium chemistries in a marine application, but most experts want us to think in terms of usable capacity as being 80% of nominal to get the rated number of charge cycles out of it. That would be 24AHr in this case, obviously.
I'm not sure I'd agree that it's a "good deal" at the price you mention, but the convenience of having the whole package put together will be a value add for lots of folks. Seems likely the pack is comprised of from 96 to 120 individual cells (either 18650 or 26650 like an electric bike pack) and presumably you don't have a way of monitoring the health of individual cells as you would using prismatics. Also I would expect the package to be fairly heavy for the rated capacity. But in a low power demand, low intensity scenario, IMHO, the package looks pretty attractive.
