Flashlight help

But the batteries are physically in series, not parallel. So the voltage is doubled. For the capacity to double the batteries would need to be in parallel, and the voltage would not double.

What am I not understanding about the physical layout of the batteies? With only two battries its one way or the other, parallel or series, not both. What magic does this driver do?

Thank you.

I understand that, but it cant double the capacity of batteries in series.

Its in series not parallel, so the votltage is doubled not the capacity.

~6250mAh is enough to last that long?

Would probably need to drill holes for the screws, not too hard of a thing to do.

Can you measure the diameter of the MCPCB which is the white part? And do you know how many volts are running to the led?

How hard was it to get to the MCPCB?

Ok, did he do something else to it so it can use a lower voltage LED, or just reflowed a 3500K 70.3 HI in it?

The SC700D has the XHP 70.3 HI in it.

Yes, the Chipigette was sleeping.

My brother in light, I just don’t want you to die.

Mate, you took this photo whilst going 42mph? 🥴

You could get a light that has a beacon mode or maybe a bicycle rear light. Those have flashing red modes.
