jon, thanks for the info on that! I don’t have stock protected 18350s so I couldn’t test one.
However, here are ome notes on the OLD versions of the RRT01 I have and the different batteries they work with or not!
The stock RRT01 works with unprotected button 16340 batteries (between 33,8mm - 34,3mm) and a protected 16340 button top battery (36,5mm, in this case a Wuben battery).
It doesn’t work with unprotected flat top 18350 batteries such as the Keepower 750mAh and Aspire 1100mAh (34,7mm and 35mm, respectively). However, it works with the CRX modded battery (flat top Keeppower with protection circuit) that has about 36,4mm.
About the triple RRT01 (that was also modded internally, in the positive contact, so that it could take flat tops) it works with all the mentioned types and sizes of batteries, button or flat top, protected or unprotected.
About the rotation tests and the changed in the values shown in the luxmeter, I’ll transcribe what I’ve talked with jon_slider some time ago when I received the CRX RRT01. They are not scientific tests, they were what they were and can, eventually, show some influence of earth magnetism in the magnetic ring of these lights:
And another test, not rotating the flashlight, but rotating myself in 4 different directions ( + ) with the flashlight on the same position over the luxmeter.
