Until those Liitokalas are tested, please don’t say that they are alternatives to a well known high current cell.
I would say that these are alternatives to the” Samsung 26H”:http://www.gearbest.com/batteries/pp_641265.html or 26F
The 30Q Buttontop are available for $16.70: DEAL IS LIVE: 30Q button top (set of 4) for your BLF Q8
I would advise you to get the 30Q - if you buy yourself a small but powerfull flashlight, you will need high-current batteries.
