Depends on what type of battery cell is in the angels? im not sure what they use, but if they use li-poly or similar lithem style battery then these should never be discharged all the way as you will ruin the cells. If its a Nimh or a NiCad then its ok to discharge them fully, As some one else stated Nimh cells dont have a memory effect like the NiCads, so there ok to charge when ever you like, as i race remote control boats we get into the habbit of fully discharging our NiCads, and cycleing them to get them to there best capacity, As with Nimh i tend to discharge them fully and cycle them every couple of weeks. But i doubt you will be pulling around 20amp (like we do in the speedboats) out of your angels so i wouldnt worry about discharging all the time.

Can you go into a bit more detail about how that happens, as a teammate had to get a battery replaced and if its because it was allowed to discharge fully then I'll need to let him know not to do it again.

Anything above the very early lcd's are nickel metal hydride (nimh), so there's no memory effect to worry about. It is okay if they discharge fully, as no damage will occur, but there's no need to, so why bother.
Years ago i used to race electric 1/8 scale cars, and for these cars i designed chargers and a battery matching system, to optimise the pack discharge rate.

quick question tom?

the manual for my fly says it does 150k odd cycles on a full charge. ive shot about 10k thru it since it was last charged and the battery indicator still thins it has a full charge. do the flys have anew battery or something? this seems tobe way oveer the 5k cycles you qouted.....

Maybe you have a super special one, with that extra bit of WDP pixie dust sprinkled in it?

I know of guys who've used their Angels in multiple tourneys without charging it, so i think 5000 cycles is a very conservative estimate.
 
150 k is the max it could do with a good battery and a full charge but you can run into problems well before this figure with the solenoid not receiving enough power etc as the battery loses some of its charge. I find it best to charge at least after 8 - 10 k shots just to be on the safe side and definitely the night before a tournament.

hope this helps :D
