Do you think it would perform any better if it had unprotected cells?

I’m not sure if its a direct drive or not. I measured about 18.6 amps at the tail with those (forgot to add that clip to the vid). I suppose I should probly own a set of 4 matching unprotecteds. What’s the best thing going in low resistance high discharge these days?

I always measure higher lumens with the Sony VTC5D vs the VTC6. You lose aoubt 200-300mah with the VTC5D though but it still has more capacity than the VTC5A.

The VTC5D doesn’t appear to be in HKJ’s comparator. I wish it was.

This is a fairly new cell I believe. I think it was made for the Dyson vacuum company, hence the D suffix.

Mooch has done a comparison here.

Honestly, I get a lot of these Sony batteries mixed up due to their name. That’s why I tend to stick to the 30Q. It has both good power and capacity and the name is easy to remember. Lol.

With a cooling period between tests I got the exact same lumen reading with the Acebeam batteries, VTC5A and Imalent batteries.

My VTC6 flat tops were too short.

They’re not charged yet but there’s no point in trying 30Q.

For my reading sphere I got my hand in with the tiny Olight S1R and pointed it in every direction to eliminate flat spots. It really is accurate.

Same here, my VTC5D’s put out more than the VTC6’s A’s and 30Q’s. Don’t really care what Mooch gets, the Lumen Tube tells a different story. :+1:

What voltage is that, 6V or 12v?

Its the 12v config. I tested while the pack was fully charged, but even if we assume 3.7V per cell under load were looking at over 275 watts. Pretty impressive I though.

Yeah, most companies making a 30,000 lumen light would use 8 x 18650 (Astrolux MF03, Imalent DX80). Only 4 cells is impressive (for 25 seconds, at least. )

What impresses me more is that those cells must have 20A protection circuits. I’ve never seen them that high. I’ve seen a few cells using 15A circuits, but that’s it for 18650’s.

Yep, the Acebeam site shows they have a 20A circuit. Really expensive suckers as well.

Liion wholesale has 18650GA cells with 20A protection circuits. I know they’re not rated for 20A continuous, but that’s where they set the protection circuit.

Okay, so no change in output. It was worth a shot.

[leggera16]

I tried the vtc6s with 3mm magnets and pretty sure i got a bump in output visually and what felt like way more heat. I wonder if my countersunk magnets contact the carrier better.

The standard batteries arrived at 4.14v so may have been a customer return or degraded. The standard batteries have domed tops which I dont think is ideal for passing 20 amps.

Cool torch so far though.

I fired mine up last night coming out of a packed Stadium, got some funny looks
