You could use a lithiumbatterypcb.com bms, they can be made compatible aswell and are much much more sanely priced.
I think, cycles are a rather bad comperable statistic. Total charged and total discharged electricity would be more usefull.
If i take the minimum cycle count & minimum capacity per given votlage from that side with a 3.6v 2.2Ah cell and do some simple (yet wrong, but good enough) math...
Guessing by the information i have, pretty much any 18650 will do the job, as long as you have 4 at least somewhat simmlar in series.
If you care about capacity, you can get some LG MJ1's -> https://secondlifestorage.com/index.php?threads/lg-lgdbmj11865-cell-specifications.1737/
