I don't want to steal all your thunder blord, but I was the one that recommended them to him as I've had good luck with them. :wave:

Any idea if these would work with 3.7-4.2v cells?

 

[awillis2589]

defiantly! I'm using one with a 16340 in my laser.

 

[Blord]

It works with 3.7-4.2v cells. The driver is linear so any excessive voltage is turned into heat. So the driver must be heatsinked very well.

I found out the driver still regulate at 2.6V. Any lower and the current also drops.
These modules are meant for two AAA cells.

I was about to order a few but I was looking at the pics of it and it doesn't have a pot, whats going on? Did you guys have to ask for a pot or something? I'm not too keen on ordering if it doesn't have a pot

 

[Blord]

My green module has a pot. Maybe ask Fasttech for the current batch modules if they have a pot.

 

[duzy]

I got my greens recently and they all have pots

 

[JollyKillBill]

Thanks guys

I have went and ordered one to try it out, I might end up buying a few

 

[awillis2589]

Its because there pictures of the bottom side. They All have pots I checked with my recent order.

 

[Blord]

I have received two more green module from Fasttech. The outputs are peak 80mW and 50mW. Still on spec but no cherry on the cream now.

 

[awillis2589]

also got 3 more two 80mW and one DOA. and a DOA 100mW 405nm.
