Current increase? Or stock driver
Did you modify the driver to accept RCR cells? Its not in the official specifications anywhere.
I remember reading the same thing about the TK70 - 26650s were never supported but went into a direct drive mode when used "unofficially"
But the driver life was never tested.
Just got this light today and put in a 16340 3.7V Li-ion cell (Keeppower protected) and it doesn't work. The cell tests to 4.18V. So I put a CR123a primary 3.0V and it works fine but gets hot fast. I'm assuming the protection circuit is being tripped on the Keeppower cell (but even in low mode?). I don't have any IMR 16340 cells but will get some if these would work better. Any suggestions appreciated. Thank you.
FYI
These lights only got a new LED. No current boost...
So do you mean that only standard 3.0V CR123a cells should be used and not IMR or any other 3.7V cell?
No what I mean was the heat you are experiencing would be how it is from a 100% stock light.
I tested IMR16340 to work great. Let me know when you haev unprotected cells to test.
Just got AW IMR16340 (550 mAh) from Illumination Supply. They work fine. Brightness on high is (subjectively) about the same as CR123a. Only difference is that with CR123a, you can see a subtle difference between medium and high mode but with IMR 16340, medium and high are same. I still can't figure out why the Keeppower Li-ion 16340 cells don't work since same 3.7 Voltage. Must have to do with protection circuit. Anyway, thank you Vinh for another great light.
I do NOT see the AW IMR 16340 550mAh batteries on ILLUM. Supply. website? I have not known them to sell any AW batteries.
I got the Kinoko IMR 16340mAh 700mAh. 😉
Yes, it was Lighthound, not Illumination Supply. Thank you for correction (just bought Efest IMR 18650 from IS). Better mAh rating on Kinoko. Both AW and Kinoko got rather mediocre reviews by HKJ on CPF.
