Using the correct Keeppowers from the link posted at the beginning of this thread from Banggood. It just seems that the springs are real pointy and scratch the backing of the keeppowers a little. It's probably normal maybe and nothing now that I look at it again.
I finally gave in and ordered an L6. Everyone keeps talking about how great it is. I could not resist any longer. Not only that I have a matched pair of 26650’s with no assigned flashlight, so I kind of had no choice!!
It’s not normal as far as I know. I have 2 of them and neither of them do that with any of the cells I’ve used. Could be a solder point that needs filing down or a spring with the end of the coil tweaked? A picture or two would help and if you have a set of calipers, could you measure your cells? There is little visible difference in the old cells and the new other than a millimeter or two. I’d like to think that all the cells sold through that link are the right ones but if not I want to know and I would contact them immediately if they were selling the old cells and do whatever I can to correct it. Feel free to send me a PM if you don’t want to put it all out here.
Without shorting the batteries, I aligned my digital caliper within a hair of making contact and the cells are just under 69mm so that looks perfect. Now, after inspecting the spring, you were absolutely correct in that the solder point needs to be filed down. Will go at it gently with my dremel and all is good again, thank you. Of course, I should have inspected the spring with my glasses on before and it would have made sense, but I did not unfortunately
I was not too far off on my guess then for turbo and high, thank you. Cold around here now and turbo mode barely warms the head after leaving it on for 30 minutes.
