*BLF LT1 Lantern Project) (updated Nov,17,2020)

It will be using unprotected of course.

Just use any 18650 you have around, and it will work, as it uses the BLF Q8 battery tube, meaning both unprotected and protected cells will fit. And it has low voltage protection, meaning I would just use unprotected 18650s in this case.

Do you think it will be ok to use unprotected 18650 for the normal people ( newbie) ?? I am fine with the unprotected…

Yep. Low voltage protection is there, like with the Q8.

And since all modes of the lantern are going to be regulated low power modes, protected cells are not really necessary.

I spoke to Barry a couple times so far via PM, once i can get a cross-section drawing done, and find somone who can to CAD design for the lantern to provide to them, then hopefully we can get it rolling more with them.

It can use both. (but will need button-tops though)

Some of the better protected cells now offer considerably higher currents of 10A continuous:

For lights with built-in low voltage shutdown I’m typically okay with using unprotected cells, even in a light that could end up being left on by mistake. Although with protected cells you will have a double layer of protection if one or the other fails.

These 10A continuous protected cells may be a good compromise for those that prefer to have that double layer of protection.

However I don’t know everything going on with the driver for this lantern yet, so I’m not sure if +10A capable cells would be required to achieve maximum output on the highest mode.

I have no idea if you tried that yet, but maybe you can ask thijsco to do some drawing? He was on the Q8 and GT projects too so he may add some experience with these projects too.

If it uses a Q8-style driver, the LVP should be pretty solid and standby current is lower than the cell’s self-discharge rate.

I don’t know him, but i can send a PM and ask if he is willing to help out on it.

100% interested

Interested as well.

I would really love to help on this project, unfortunately I don’t have the time. I joined our fire department and the training has just started so that takes all my time atm.

That being said,maybe fritz15 is interested?

Thanks for chiming in :slight_smile: I don’t know Fritz15 sadly either or if he would like handle the CAD needed for this project.

If in the end there is no one who will do CAD drawings, I can assure you that Thorfire is perfectly able to do the drawing themselves as long as they get the information. In the Q8 project all the important details were communicated via crude drawings in Paint, and even hand drawings, they converted them into technical drawings that were sent to us for evaluation. It was not perfect but it worked.

Especially since they obviously have the q8 drawings it might be easier if you go through thorfire directly.
As djozz said with the q8 they did all of the work off some easy to make crude sketches and drawings.

I am also interested.

Raptor2018 and schlafsack01 added as 769 and 770.

Next person interested will get number 579, somehow it got skipped.

List sorted by user name is now formated to be easy to read, just scroll down the list and see how many lights you signed up for, and the number of each entry.

DBSAR, Just let me know when you want me to send you a .rtf version to post on the first post.

In for one.

Please add me to the list, thanks!
