    Interesting use of Lithium-Ion Battery

    I had to laugh. It was embarassingly easy for me to get through the withdrawal. Just a $75,000 surgery and a morphine pump for about a week and I didn't even think about cigarettes. :thumbsup:

    Interesting use of Lithium-Ion Battery

    These are all the rage at my office. I quit smoking the first week in December, but prior to that, I noticed the smoking area was becoming inundated with electronic cigarettes. I just wondered why bother coming outside, in the cold? Just stay at your desk or go to the break room. There have...

    DIY 18650 protection?

    Has anyone here added protection to harvested 18650 cells? I ran across this at DX: http://www.dealextreme.com/details.dx/sku.26112 I would not have known what I was looking at, if it wasn't for the two threads showing disassembled protected cells. I've got several unprotected 18650 cells...

My digital camera battery charger matches the same voltage and mAh output as the 18650 charger (it turns out the R/C charger I mentioned above is for NiCad so there's just too much juice for Li-ions). And by the way, my wife is going to be in Houston this week so...

    Desperately seeking charger...

    Thanks for the replies. Lighthound is south of Houston and if I have the charger shipped overnight, I'll be paying $34. :faint: I have an old charger for an R/C car at the house. It was for a 7.4v battery pack. Could I gut my fried recharger and use it as a holder, with the R/C charger wired...

    Desperately seeking charger...

    My 18650 battery charger fried out last night (it made a loud pop and then quit working). I can order a new one from DX but I'll need to recharge my batteries before my commute to work on Monday. Is there a store that carries chargers for 18650 batteries anywhere in the North Texas area? I...
