Bomb V2
Vapcell M11V2 gives 23A max, ~18A stable for a few seconds, surprisingly less than H10 which somehow held 30A easily

A 14500 vapcell h10 could hold 30A?? For any time at all thats very impressive!
Reflowed SunLike 2835 3000K into 6x18650 powerbank which originally had low CRI ~6000K LEDs
Fiberglass PCB had moist or something else between the layers, sounded like popcorn popping while reflowing

Reflowed SunLike 2835 3000K into 8x18650 powerbank which originally had low CRI ~6000K LEDs, for some reason one parallel didn’t work for the first time, fixed by dropping a solder blob to the side of the LED to avoid disassembling again

This is the best portable 18650 powerbank for that price, recommended.

What tool did you use?
I got the same one and I also have the same leds on hand

Swapped some parts around my lights
S3: LHP531 5000K, 3v20a buck, 30*60 degree stripe TIR lens. Nothing interesting here; just floody ~6000Lm
T5: LHP531 3000K with unregulated T2 driver, 30*60 degree stripe TIR lens, thin battery tube from T6. BTW moonlight is great on that driver compared to other Convoys. I’ll put NV1010 R9080 into it after release
T6: NV1010 5500K on a 9x16mm copper sheet spacer, AA/14500 5A boost-buck, short reflector from S3 and thick battery tube from T5. It should be at least 180Lm/W in all modes. Finally the joints look ok, but still dirty
Maybe I’ll post more photos of other mods, like Nitecore TINI2 519a or CC driver updated “ConvoyFire” battery boxes along with some DIY “bombs”

Funny, I called my FandyFire + Convoy Frankenstein a “Fandyvoy”.

Superfire HS60 with Samsung LH351D 5000K
The beam is now without severe tint shift, looks like it became a little brighter, CRI is obviously better
UI is quite simple: click for high/med/low/strobe/SOS, hold to turn off.
There’s battery indication on the button. Charging port cover is stepped, it won’t pop out for no reason. Plastic bezels are used, so disassembly was easy.

I decided to go with just one battery, since the magnet can’t hold all seven; besides, charging would be a hassle if they were high-capacity cells.
Now there’s no flickering, and the brightness is stable. It will run for about 7 hours at the 30% setting, which is roughly 200 lumens.
10% brightness is enough to light up a desk.
The minimum setting (1%) provides enough dim light to navigate the room without bumping into things, and it may last for about a week.
A full charge should take about an hour and a half.
Even though Duv is really high it doesn’t look horrible, I like it.
