After some days i am back.
I am desolate and embittered of the problems incurred to some members. I have spent many hours (days) of my life to this project and i am angry that something go wrong. The fact that this occurs to people with my same passion in flashlights makes me more sad.
1) From when i received the sample i never had a shortcircuit or malfunction, it is obvious that i would have say. I tested KeePPower 26650 5200 protected, LG HE2, Panasonic PF.
The problem as i read in the previous posts is the difference in the diameter of the positive pole: Efest have a wider + pole than KeePPower. So only with some battery the positive contact touch the brass pill creating a shortcircuit. Neal has find a solution with adopting a plastic washer on the pill. This will be included in the next batch.
I will remember that i have NEVER requested a 17 mm driver but a 22 one because of the dimension of the JAX Z1 pill in fact if this had been respected this problem never happen.
2) Some members report a possible short on the anodized cover with cables soldered on MCPCB. The anodized aluminum don’t conducts electricity (thanks to anodized threads a 1/4 turn on most flashlights permits lock out). The only reason why this cover can cause short is some sort of damage on anodization in some lights. I will ask Neal to make some type of insulation on next batch.
Members that had short circuit with melted springs or a light that doesn’t work please send me a PM i will try to find a solution.
Some specs not respected in production.
-In the OP of this thread i declare the use of 20 AWG cables. Now i see 24 on production one. I don’t understand why change a spec commonly agreed with manufacturer.
