Most of the cells in my packs are the standard "16 hour" charge at C10 variety. 90% of the time I fast charge my cells at C1 using my Accucycle (500mah rate for 500 to 700mah cells and 1000mah rate for 1100mah cells and up)

I am quite cautious, however, with my 1/2A packs (250mah) and the park flyer 6 cell 250 packs as they get too warm for my liking when pushed hard.

I prefer to slow charge them on 25mah overnight, or quick charge on a slower rate but watching the packs as they charge as not to let them get hot.

Speaking to the owner of SR batteries last year (I got a few packs made up from Larry) he suggested NOT fast charging if you want your batteries to last the longest time. Thats not allways possible in many of our cases, so I accept a shorter cell/pack life goes along with the convenience of fast charging.

You should check with Chuck Smith. His theory is bigger better (batteries and charger) and throw them away if they stop working.

I have hand launch gliders with cells in the 250 ma capacity that you can only charge at 50 ma max. There may be those among the readers who will take things we say as gospel and might end up damaging the cell packs. I urge each and everyone of you to follow the manufacturers recommendations on fast charging. Not all cells are the same.

Good call Dennis

My airborne packs are all 4.8V 1100 mah AAU cell Nicads, they are very light for their capacity (same as a standard 600 mah pack).

I have both 1100 mah AAU TX packs as well as 1650 NiMH packs that I charge like that but I dont take the 1650 NiMH over 1C. I have hit 2C on my NiCDs at contests when I want to top them up between rounds.

I do have a couple of 300 mah 11 cell NiMH that I use on my IFO that I have charges with rates as high as 600 mah, it has not appeared to cause any damage yet, but I dont use them that often.
