    Lithium is not unsafe if handled properly. In the earlier days when the cells did not have failsafe measures it was a bit more risky. The main rules are don't overdraw it, short it(terminals together) or charge it above its rated current. I have used lithium for years in model aircraft, power tools and other items(everybody's cell phones for instance) and the only issue I had was with one set freezing. Most are freeze tolerant but some are not, certainly not as tolerant as nicd or nimh. That is why my bike headlight setup is Nimh at the moment. Lipo would be way lighter and smaller...

    The quality of the charger is more important than the size of the cells. Good chargers don't have to cost much but they will have specific peak detection modes and thermal sensors, both of which will prevent a thermal melt down before it goes haywire.

    The batts i almost went with can put on 10 amps thats a lot of darn current but they was only like 2200 mah so the run time wouldnt be good. last night i was doing a run time test on one of my flashlights and in 1 hour it was to hot to touch .made me wonder what would happen if it released all its emery at once

    Be sure you understand well the shipping requirements and constraints if you plan on reselling and any of your shipments will be by air/UPS/USPS/Fedex/etc.

    You will need to meet labeling and documentation requirements and are limited as to the number of units you can ship in one box. If you plan on selling to Europe, there are a whole bunch of other regulations you'll need to meet.

    Can be dangerous. I know of a F-15E pilot that threw a spare lithium battery for his NVGs in a chest pocket of his flight suit. The battery came in contact with his car keys and shorted. The resulting runaway condition of the battery caused 3rd degree burns and shrapnel wounds from the exploding battery.

    With lithium batteries...

    impact is bad
    moisture is bad
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    No kidding. I became a big believer in a strip of electrical tape around those suckers.
