A great product indeed! Working nicely.
This is really a heads up for anyone having issues with switching modes on the Challenger 2. Luckily SanWu has excellent Customer service.
Thanks Francis!
Li ion batteries- no prior exposure.
I learned that the Lithium ion batteries are named by diameter and length- with the second set of numbers being the length in millimeters. So an
18650 is 18 mm in diameter and 650 mm long.
Except when they are not!
First the are 18650' that are protected-and are longer than standard 18650 *while still being labeled as 18650.*
But not only that- but there are variations in the length of different brands of Protected 18650 batteries.
That last is relevant because although I bought high quality Nitecore Protected 18650 batteries-I had odd issues with my Challenger II not igniting all the time-and the multimode switching was not working. Slightly unscrewing the tailcap/switch helped.
Francis at SanWu gave me a link to Orbitronic and I bought some of their version of the protected 18650. Now I can switch from 1mW, to half and full power!
The Nitecore Protected 18650 was a few mm longer than the Orbitronic Protected 18650 which pushed in the power switch slightly when the tail cap was fully tightened. This disables the switching of modes since it requires pulsed off/on sequences
I'm guessing that there is no exact length standard because common devices use a spring which can adjust for variation in length.
