Sofirn IF30 uses 32650 battery. I looked it up on Vapcell, but no luck. Are there replacement batteries other (and perhaps better) than the Sofirn-wrapped included one?
I dont have an answer to your question but why do you want to replace the “Sofirn-wrapped included one.”
Exactly. Sofirn and Wurkkos use pretty good cells.
I use 'em with no problems whatsoever. Even my stockpile of genuine 30Qs and VTCwhatevers are going neglected because I haven’t needed any new good cells for lights.
There have been concerns:

In any event, what would be a decent cell of this size for a spare? I’m not even sure if Sofirn sells spares for this light.
Unno. 32650s are almost the same dimensions as D cells. Never played with any of those, just 26650s and 26800s (the Queen Something ones) as the biggest.
Is your cell getting hot after a few sustained turbo runs? The thread you linked might have tested a defective cell. I can chime in that Sofirn puts some effort into selling a decent cell. Definitely not known for having issues with them.
Surprisingly, I still use 10 year old unprotected Trustfire TF32650’s with zero issues. Other’s have also touted this cell when they were first introduced. If you decided to buy some, you should probably purchase direct through Trustfire’s official site (which were available a few years ago), as there are a myriad of counterfeits selling on ebay, aliexpress, etc. Someone mentioned they had a US based CS number, which came through selling some newly produced, unprotected versions and extension tubes. Beware of old inventory!
HKJ tested the TF32650 @ 6000 Ah for the protected version. The protection circuit reduces discharge current and capacity. If you can find the unprotected versions, discharge current is increased and tests show a capacity of around 7.5 Ah. These are NOT high current cells and use old tech. I use several on series for higher capacity, so the load is shared among cells.
26650’s have advanced more than 32650’s.
I can’t see any reason why we wouldn’t sleeve a Vapcell K62 (6200mAh, 15A CDR) for half the price of a protected Trustfire TF32650 (6000mAh, ??? CDR).
