What would be the typical number of full life recharge cycle for the Radio Shack 8 cell NiMH 1600mAHr battery pack if each dishcarge is approximately 10-15 minutes with a T-52, S400, GB 2.5:1, and 9x6 prop? I am guessing the current is ~10 amps. The packs have been fast charged at 1.6A (C) and slow charged every 10 cycles at 160mA (C/10).

I couldn't tell you the limit, but I'm at about 50 cycles on my 1600's and 1420's, and they're still as good as new - at least no change that I can tell..

I'm at about 50 cycles w/ a 1600RS NiMH pack.. still takes 1650mah on a charge.. I charge at 1 amp.... but, I can hear the cells "popping" near the end of the charge.. venting I assume.. I'm MUCH happier w/ my Sanyo 1650 NiMH packs.. better peak voltage delivery throughout the discharge cycle

I've got 60-70 cycles on one and haven't noticed any change at all. I run them on a S400 with 3:1 GB and 9X6 APC Slow-fly and charge them at 750 ma.

Thanks much!

I have about 45 on mine and am experiencing some flight performance degradation. A different thread targeted my motor as the likely item needing replacement, but I was still interested in what to expect from the battery packs.
