Right.
I cant see this driver backsides with 4 independent cell contacts. I immediatly imagine big badaboom. Also, I cant understand how do Lexel and others plan to fix tube in right position - which is necessary with 2 screw holes in driver (ie you cant rotate driver to proper position to align cells).
I didnt found any simple ways to make 2s/4s mod safety. Im going to:
- reverse battery tube.
- use stock tail pcb place (now it is faced to the driver) for medium board (#1 for 4s or #2 for 2s), so you could turn tube in head without any short-circuit risk
- make custom tail. With deeper threads (stock tail wont allow to screw all down to the head side tube threads) and with place for custom tail board (#3)
make custom tail insert that have “pins” which could fix between cells and rotate (together with tail board) inside custom tail
I suppose I listed enough information why did I had to ask this question.
I had lots of button top cells, and many lights with mechanical reverse protection. Not any combination could work.
Mine in somewhere between customs and local post office, over 40 days average delay for this part of the trip alone at this time of the year, hope it arrives soom
Are you still planning to make M8 quad pills? Not asking for ETA, but right now I have an empty host which I’m wondering what to do with, so if it’s confirmed I’ll wait for them to be avaiable before making any plans.
I have to make more custom retaining rings for one project soon, but still dont have any feedback about previous ones (that came with S2+ pills and P60 shells). What do you think about cut width? How do you screw them hard (what tools do you use)?
18mm rings have thin cuts (I decided that cut shouldnt be wider than ring thickness to save this part rigid enough) and they are not comparable with most retaining ring pliers. I prefer screw it down (without driver spring installed) with stainless steel ruler. Should I make the cuts wider next time? I dont feel using retaining ring pliers for screwing brass rings, they can damage it with ease.
Note: Im talking about thin rings that can take two-side drivers, common decision with two holes in thick ring is not suitable for this situation.
Well, even if I’m not using the ring and the pill - yet (I’m still missing the other components for the build) - I feel comfortable about the ring and its dimensions.
This is a photo of your S2+ pill with the custom ring and a driver from Lexel. It is double sided and has 6*7135 chips on the back! It fits perfectly and can be screwed in easily before being in the flashlight! So far I had no problem. And that is the reason why I ordered more.
Although I grinded 2 “normal” rings of regular S2+ pill, it doesn’t have the same effect, as we lose the “holes/cuts” to help screwing in the ring. Normal S2+ pill and grinded ring on the left and kiriba-ru’s S2+ pill for triple mods on the right.
Your custom ring, for double sided drivers is pretty nice!!
What tools do you use to screw/unscrew my ring? As for me it looks little damaged. Not sure it is possible to avoid edges of cuts from bending when it is made from brass.
