Would the Q8 driver be a useful driver for it, and will it fit?
Simon, I noticed the new driver for AA, 14500, 16340. Will it also be available with 12 groups (biscotti clone)?
Hum, it says “1–10–35–100” and will probably have memory (they normally do…).
Would be nice if it didn’t have memory Simon or at least if it was configurable 
This will be a good combination! I would buy it.
The battery configuration, I think is correct and does not need modification.
It can be another good combination.
I don’t know if it fits. As it is I don’t know, but I think the screws would make using an adaptor easier.
Yep, the batteries are all properly set up for a SBT90.2 - parallel.Could even make a triple, like the old SolarStorm/FandyFire SP03. Originated back in 2013, but again, a nice quad cell soda can base. I got one running a FET+1 with triple SST-40's, ~8000 lumens, ~260 kcd.
Always wanted a big triple head for a Q8, but closer to 100 mm width, equal to the old Shocker that basically had 3 C8 size reflectors.
Simon’s smashing it with the biscuit drivers!
Discription indicates “turn off if the voltage is below 2.8V (low voltage protection for lithium battery)”
I’ve been looking for a good 1A/2AA/14500 driver - does this mean 2xAA will only work until 2.8V?
There's no mention for dual cell operation in overview. It may have issues with 2x fresh cells out of the charger, and it could also have problems regulating the moonlight mode.
If the input voltage is 2-2.8V, the driver will not work.
Is there a resistor (4R7?) that I can remove that would bypass LVP, if needed?
Can I ask what the PWM frequency is for the AA / 14500 / 16340 driver is, please?
I seem to remember people saying the original Convoy T2 had visible PWM.
In these days I finaly understood how most of AA/14500 drivers work. They boost voltage from 1.5 to 4V for example to power MCU and additional electronics. When the input voltage is bigger from setup output voltage boost doesn’t work and just output voltage is the same as input. So the simplest method to control the LED is to be used PWM in most of cases.
Oops I spotted MCU label on new 20mm linear driver 
I see no reason as to why the newer AA/14500/16340 driver should have PWM. It clearly is a regulated driver,
which boosts voltage when input is from low voltage cells, and when it receives input from li-ion it should either buck or work in some sort of linear :???: mode. What do you think, icpart?
Look at the MOSFET switcher in that driver, above the schottky and to the left of the inductor. It's really tiny!!!
Most boost converters goes in pass through mode when input voltage is above output voltage so I wrote the simplest method for control is PWM. Most cheap drivers use that method, but here you are maybe right. I can’t identify which component is boost controller maybe that device which you point is boost driver ic. But if you look bottom side of PCB there is sense resistor. So I think they used the same linear regulator after boost converter. They don’t regulate the boost driver. AAA0 is probably mosfet transistor which works as linear regulator. Another device at the same PCB side is our favorite opamp which control that mosfet.
That tiny thing with the letters 11G on top is using some 2×2mm package, being right next to the bulk of the driver's (copper) cathode. I think it must be some MOSFET.
You mean that, when the driver detects high input voltage, that tiny and poorly heatsinked A00D part is the MOSFET? Well, I don't think so. I could know more, but that looks to be part of the current control feedback stage, or sort of. :???:
So if that AOOD is not control mosfet it will be need only for turbo. From PCB traces I can see that. If another device is main switching mosfet how the circuit will work from low voltage AA battery. Also input LDO, OPamp will need higher power supply voltage. Another way is if MCU stared to work from 1V and if it control PWM signal for mosfet based boost converter. But I’m not very sure is that in the case.
AA/14500 version non-PWM
Sonix SN8F57-something? SN8F570200?
Oh, that is nice :+1:
Thank you, I’ll add that to my list of stuff to order (when the UK gets out of coronavirus lockdown).
