2 cell (Li-ion) drivers

I have searched through several pages of this subforum and didnt find anything.

Can you suggest me some budget drivers for 2-cell lights.

I need them for STL-V2 and Small Sun TY-T13 flashlights.

In first flashlight I want better mode arrangement, and in second flashlight more current.

Is there some 1-mode, 2-mode 2-cell driver, or some driver wich always starts at high, or wich has very quick memory while on.

There are great 4,2V drivers, but I cant find some cheap (budget) dfor 2-cells.

I already tried modding STL-V2 with SST-50 driver from dx, the current is good, but it has 5 modes and very slow memory…

I’ve been working on a way to use amc 7135 drivers with series batts. I just finished testing 3xml with 12v supply. Not a buck driver so 8.4V would work with quad led pcb(2s2p). Not for single led light. In this thread
You can see how. Post #84 shows the chips mounted on a separate heat sink. I’m not finished yet but 2-cell lights were one possibility I was considering.
