How do you know when to stop charging, does the chargers have some kind of indicator?
It seems like that kind of battery is sold out everywhere I look do you have any tips on where I could get some of 'em?Thanks for the information guys! (:
I would be -very- cautious about building my own LiPo charger. A little overcharge, temps rise to much, poof, fire.

How about a 123A
maybe these will work for you:charger:https://www.sparkfun.com/products/1021740mA li-po:https://www.sparkfun.com/products/11316110mA li-po:https://www.sparkfun.com/products/731I have used all 3 of these in projects before...NOTE:Im not sure if that 'charger' is best to be used with the 40mA battery though.. (read comments...etc)I think min current is like 100mA or 500mA or something?) I 'have' chargedmy 40mA battery with in.. but never just left it charge.... brief periods.Seems to 'work' (but not sure if its 'safe' to just trow it out there without a warning)
http://www.rchelicopterfun.com/rc-lipo-batteries.html"never charge a LiPo or LiIon pack greater than 1 times its capacity (1C)."So, a 40mAh LiPo must never be charged at more than 40mA. Less is okay.
QuoteLiPo batteries do not like to be deep discharged. If you completely discharge the battery, you risk a fire.I don't believe that is true. LiPo can suffer fire damage from overcharging or over current draw if no protection device(s) are used, but overdischarge just causes a cell failure such that it will no longer except a new charge, but not fire damage.
