Yep, the flashlight is powered by two cells in paralel, and two in series.
When I was measuring the standby current drain, I checked by “bypassing” one of the 2 cell group and putting the DMM in series in the other group. I was able to measure a 2.2A drain in High mode from on the the series, so I guess the full current for max output whit fresh eneloops is around 4.4A (2.2A from each series).
AFAIK, Nitecore EA4 has the same battery distribution, and similar buck driver performance.
Maybe this is an interesting idea.
Do you know Nextorch MyTorch series? MyTorch18650 has a recharge MiniUSB port, which also works for the customization of the light UI.
Just in case manufacturers reads this, what about implemeting a MicroUSB plug for the charging feature, that can also be used to customize (just like the MyTorch series) the user interface via a simple PC sowtware with your OWN mode sequence?
I mean, you kill two birds with one shot (spanish say, not sure if it has sense in english or nor, lol) if you put a “universal” phisical conector that also allows you to give customer the power to customize and fine tune the tool to his own needs or taste.
Nextorch get it right, interesting idea, but unfortunatelly the series are in the “soft” side, with very gentle max outputs.
I like the microusb charging idea, although as nicely as this light is built, I still wouldn't pay the higher price with the modes it has. Your microusb programming idea should take care of that.
I'm only a few years late but I got my SRA40 today. It is by far the nicest 4xAA light I have in my collection and the fact that it has a charging port is a real bonus. There just isn't any 4xaa light in my collection that is built anywhere near to the solidness of this light. I have a DA40 on the way, but from the pics alone I can see it won't be built like this light. I think this light is going to make the perfect christmas gift for a couple of people.
After getting your D40A, do you still feel the SRA40 is superior? Seems like there’s a notable weight difference between the two (DA40 - 165g; SRA40 - 245g)
No not anymore really. What I do like about the SRA40 is that it does not have a battery cage, UI very simple, lighted battery indicator and that it can charge in the wall, but bummer that it doesn't have usb charging.
D40A has a nicer beam and purer white, ss bezel looks nice, far slimmer and light, moon and beacon mode. If I had to choose, probably the D40A overall, but for a gift to someone, I would always choose the SRA40 as the battery cage on the d40 can be very annoying for someone that wants a really simple light.
Thanks. I decided on the D40A, because the battery cage isn’t an issue. Looking for a replacement to an Olight S35 Baton that was lost (that has a battery cage).
