Sofirn Q8 group buy (gb closed, but try PM to Sofirn for discount)

An explosion in an open charger is bad - An explosion in a sealed light is a pipe bomb

This type of emo-reasoning does not help the discussion wether or not to add a charge port.

You need at least a new electrical connection from the battery+ to the tail PCB for that, not impossible but it requires quite a bit more than just some extra components.

I canā€™t get over how many people want a charger built into a flashlight. They want it cheap, donā€™t want to pay for quality components, but donā€™t want to lose life or limb when it all goes awry either. Not sure how anyone thinks a quality balance charger can only cost a dollar.

I, for one, simply will not charge a cell in an enclosed aircraft aluminum pipe. A good number of the lights I get with this built in charging feature get the charger eliminated quite quickly. I also seal the USB port with Sugru.

Why would anyone let a 5 yr old handle a Li-ion cell and charger? The new generation is getting lazier all the time, itā€™s so disappointing.

Plus how would you control each batteries individual charge? Some people might run 4 batteries where you would want at least 1A each or 4A total charging power. Some people might only use 1 battery in the light. If you put all 4A to one battery itā€™s too much. So it is very difficult to control.

A built in charger would almost assuredly require a sealed battery back. People really donā€™t like battery packs.

This conversation has nothing to do with the current Q8. The future Q8 v1.5 thread is the place to talk about it. Q8 v1.5 here.

I forgot to ask, is the SP36 being discussed in the open or just through private messaging? It sounds very interesting.

Correct, this thread is about an existing light that does not have this horrid feature. :wink:

But for the record, where I come from the parents that were responsible for the safety of that 5 yr old should go to jail for allowing a charging Li-ion cell to be in the childā€™s possession. Criminal negligence or whatever you wish to call it, reckless behavior at the very least. We have spent years here stressing the importance of proper safety where these Li-ions are concerned. It Really is THAT important!

It happened about 2 years ago. I worked as a paramedic then. I donā€™t know the law in USA. Parents claimed it was an accident. In my country I canā€™t realise that a court could be so strict to leave the child without parents after this. Parents have the punishment to the end of their lifeā€¦ Probably they got a suspended sentence and the life went on.

@Quad-XXX, what are the details of the story? I would love to know about it.

I would like to know which charger was it, what battery was it, was it shorted accidentally inside of the charger, etc.

A lithium ion cell does not explode unless itā€™s in complete meltdown and it does NOT have vent holes. Some counterfeit cells do not include these safeties, so it could be the reason.

@Quad-XXX, when I stated above that this type of reasoning is not productive in the discussion, I was not aware that you were actually there with the incident. It makes more sense to me now that you used it in the discussion. :+1:

Letā€™s not encourage off-topic fear-mongering. At least not in this thread. It tends to have unfortunate effects on humans, and there are other threads where it may be more relevant.

Quad-XXX, the Q8 has no built-in charging because most people didnā€™t want it, and they have valid reasons for their preference. If someone wants a version with charging badly enough, they are free to start a new project and a new thread for it, but painting gory pictures here is not a productive way to make that happen.

Safety is important for high-power devices like li-ion cells. People should only use quality cells and quality chargers, with someone around, to reduce risk of fires or injuries. Cheap cells and cheap chargers are known to be dangerous, especially if left unattended.

@BlueSwordM Do you know the difference between a paramedic and a policeman? All I remember was an ice, searching the ice, shouting the ice, punching all neighboursā€™ door and calling more ice. One hour later I had to be in the another place.

@djozz No problem. Everything is fine.

@ToyKeeper True. True. So trueā€¦

Just wanted to let everyone know my Q8 XPL-HI came in today. Pretty awesome. I may buy another from Amazon when they arrive. I would think that will happen pretty soon if mine has made it in. Thank you djozz and Sofirn (Barry).

@Toykepper, I understand.

@Quad-XXX, same thing. Sorry. Iā€™m just a bit too curious sometimes :weary:

I donā€™t really think the Q8 needs onboard charging though.

This is the design.

But finally we decided to remove the flats since many BLFers donā€™t like it.

We are going to use NarsilM V1.2 firmware. Thanks @Toykeeper for help!

Sofirn Q8 to USA was delivered on 17th, but it takes about 7 days to be available. :person_facepalming: Hope amazon will make it quicker.

Hope people there recovered from the hurricane soon.

Looks Good :slight_smile:

Digging that SP36. Put me down for a few of those. :smiley: Hope Amazon US gets those when they are available.

Interested US

Looks good. I must be the only one who actually likes the flat. I'll buy the SF36 with the battery tube with the flat sides if you can sell it to me when it becomes available?

I think the flats look good too.

Edit: This is not something I have a strong preference about. It makes no real difference to me.
