The sad thing is that you/they are probably right.
A disaster waiting to happen is the widespread use of LiIons in e-cigs. Sales are exploding. My guess is that a lot of really rubbish cells and chargers are sold to totally unsuspecting customers.
I recall that, vaguely. I’m sure they’re hoping it was long forgotten.
Perhaps a competition for the stupidest thing anyone can manage to shrinkwrap in a Fasttech wrapper?
Little Vienna sausages, partly smoked cigars, sardines, lipsticks …… credit Fasttech as the supplier, get it up in search results, YouTube an award ceremony …
But beware! A second cap can result in a decreased performance since the internal resistance rises. At least at higher currents this could be a disadvantage. I found this article with measurements of current Keeppower 26650 cells (in German) which performed better when the additional cap was removed:
Personally I think we only have ourselves to blame
All us blf members so efficiently emptying every battery recycling box we see of laptop batteries and power tool packs
There’s now nothing left for the Chinese to use to f/make Ultrafire batteries with, so their selling off the ultrafire labels and metal tops to make ends meet :bigsmile:
I thought I’d strip off the old wrapper, super glue the button tops to the cell, place one of the sealing rings on it, and then put on a new battery sleeve. In order to reduce the resistance with the cap and get a better contact I would also drill a hole in the button top, run a small braided wire through it, solder it to the cap, and then solder the other end to the positive top of the laptop cell.
Since this is a “new and improved ” battery I’m thinking I’d write HonestFire on the battery sleeve, 12000mAh capacity and good for 100A draw. Should be easy to move a bunch of them on Ebay for $19.99 each. But for BLF members I’d be willing to discount to offer a 5% discount
Very true. I was thinking of drilling a hole in the top of the button top and running some braided wire through it. Then I would solder it down and solder the other end to the cell. Super glue, a sealing ring, and a new wrapper and the battery should be good to go.
All my lights take flat tops but I’ve been looking at headlights that only work with button tops, hence the reason why I’m considering doing this.
