Will be soon, just don’t have enough time to finish it 
The FastTech S2+ linked is 7135 x4
The S2+ linked by M4D M4X is 7135 x8
FT offers also x8 but BG is still cheaper with that code.
In addition BG offers faster shipping for only little money.
will this take 2 batteries ? cause in the specs says Voltage: 3.0~4.2v
No,
Battery Configurations: 1 x 18650 Battery / 1 x 26650 Battery
strange cause in the review it says it was able to handle 2 batteries : Review: JAX Z1 (1x XM-L2, 1 or 2 x 26650/18650) + they sell the extension tube
any codes for xtar chargers? like MC1, or MC2?
Well, you never know what will you get with those chinese drivers until you try.
Edit: ah, there you go, it works 
In TLF they got it working with 1-2 x 26650/18650 (2x with the extention tube), also protected cells will match, or 2x 18350.

Uses 3 x 18650 flat top unprotected batteries which is a real shame for me as i point blank refuse to use unprotected cells and only using flat top cells is rather short sighted imho. Ah well maybe a V2 will address these issues.
All i use are unprotected cells, never had an issue.
The specs say over discharge protection and “overload” protection , does that mean discharge amps or charge volts?Anyway,it would need testing to guarantee it works , but , in principle ,and using a decent charger , I prefer protection in the torch and unprotected,lower internal resistance cells.I’ve even ordered a 20 pack of Seiko protection pcb’s from Ali Express to fit in line with drivers.Everyone has their own solution.
Does anyone know if there are any codes for the Panasonic PF cells?

BLF should work on batteries.
NEWBG seems to have expired.
