Thanks.
Batteries ordered. Glad to find a US supplier!
Totally OT -
I almost ordered a Convoy S3 clone to DIY but that would be my first attempt entirely. Am I likely to get it right and be happy with the finished product? I can solder…
Not sure of what parts I actually need or get to chose from. I have the parts from my broken “Unbranded 18650 XM-L U2”: Review: Unbranded 18650 XM-L U2 Flood to Throw Flashlight / Headlamp Combo. I think i burned up the emitter so it would really just be the ‘clicker’.
