On 1x18650, the runtimes are 1/4th as long as with 4x18650. It is a consistent ratio. If you know the runtime with 4 cells, you also know the runtime with 1, 2, or 3 cells. Just multiply by 0.25, 0.50, or 0.75.
Very true, which will be determined once we can get a production prototype to test each of the stepped modes using good brand name cells. Right now i have not really tested the V2 with its current set up & amp-drain at the different modes, but the V1 was tested to run well past 12 hours on maximum mode on four good cells.
This sounds interesting. I would like to be counted on for one .
I’m in for two more. Should be a total of four.
OH HELL “past 12hours on MAX”…. CRAP I think I need a total of 4 now so please make sure am down for FOUR IN TOTAL
Late, but please add me for 1 lantern.
I will commit to buying two (total) of these.
Has price been discussed, and I missed it?
As far as price goes, nothing is settled but likely $30-$40 I believe.

OP Updated to that list

We could increase that to 40 hours on max by removing all but one chip on each power channel.
This lantern could make good use of the Sofirn Q8 extension tubes if designed to fit. Imagine having the lantern fueled with 8 or more 3500mAh cells. Runtime for ever

Don’t you mean 16 cells
driver will be likely without power bank equipped but its there, not sure how this goes
Don’t you mean 16 cells
Well yes, but I wasn’t going to be that brash… But I do like the sound of 50,000+mAh… lol
I do wonder how it would behave on a tripod though.
Would make it a very nice night table lamp
I had not seen that someone was doing extension tubes (I think). That is a very good thing .I have a Fenix TK75 with three extension tubes. Excessively expensive at the time, but a good light. The first set of 4 batteries is “regular” bedside. The next three sets are sitting (charged) in the closet for when really bad crap has happened. I had hoped the Q8 would have extension tubes; but it did not. This is good news for the lantern and the Q8 if available. I am primarily an emergency light person. We have earthquakes, bad storms, Tsunamis, occasional tornadoes, and forest fires. We don’t have immediately active volcanoes; but there are several in the area. Think Mount St. Helens.
Attention would need to deal with vertical stability with multiple extension tubes. A good stand would fix that.
I continue to want some of these lanterns.

Will those driver boards be sold separately in your driver sales thread too, for some who might want to mod their existing Q8 lights or other SRK-style lights?
EDIT: I just noticed your (re)programming pads are there, which is cool. But, looking closer, they are interfering with the ATtiny footprint, or rather the ATtiny footprint is interfering with the (re)programming pads.

There is a picture with 8 extension tubes. That makes 32 cells

They should.
You are reprogramming the ATTiny with them.

Looks good!
i agree that this first lantern version don’t need the power bank, just the ramping design & built in charging. The AMC design is perfect for this first production lantern model.
