Are these two batteries actually different?

No. Both are the Limitless Lithium Nano-HDv3 with 30Ah capacity and a 6,500W rating. Pick the listing with the lower price and better availability.

Which has more cranking power?

Product A lists 1,800 cranking amps and 1,350 cold cranking amps. Product B lists no cranking figures, so the only verified numbers are on product A.

Can I use this in a car with an alternator?

No. The manufacturer limits it to motorcycle and powersports use and excludes vehicles with an alternator. The wattage ratings assume a 14.8V input from an alternator or stator.

How long will a 30Ah battery last?

Runtime depends on load. At a 400A draw it is rated for about 30 seconds standalone, and at 800A for about 10 seconds. Real-world play time depends on your stereo or accessory draw.

Is the BMS worth having?

Yes. It disconnects the battery if voltage rises above 15.3V or falls below 10V, which protects the cells. Product A documents this; product B does not list it.

Can I return it if it does not fit?

Product A states no refunds or exchanges on batteries. Check product B's seller policy before ordering, and confirm the BCI Group 30 size fits your bike first.
