Thank you all for the solder blob compliments.
I’m a bit bored during the Christmas holidays and I’m still waiting for my light thus I tinkered a bit more with the blobs.
I used 800 grid paper to sand the blobs down.
Wrapped some tape around the cells and put them into the tube of my Convoy S2+.
The bigger surface of the tube helps to get a perfectly aligned grinding. Just press with one finger onto the cell and scrape the cell and the tube over the paper.
Now they look more like button top cells.
Just have to wait for my flashlight to arrive now.
I just disassembled a second-batch Q8 to measure the grooves and o-rings for you with a caliper.
The battery tube’s o-ring grooves are approx 47.9mm. The o-rings measures approx 41.0mm when relaxed. Their thickness is approx 1.4mm.
The bezel’s o-ring groove is approx 52.0mm inner diameter. The o-ring measures approx 54.0mm inner diameter when relaxed. Its thickness is approx 1.8mm. Yes, I measured the o-ring as larger than the groove it sits in.
I’m almost want make my purchase from BG until see this price. Tempted with such price, temporary no update coupon that near to GB price.
USD 35 are price that subsidized by B2C platform.
Seller mark price USD41 which same like our GB price.
I’m in previous GB list but miss the date.
Lucky enough to avoid those first batch issues.
