Default What about these new very large Tx batteries?

Here's my situation. I usually fly 3 or 4 days every week. I do a fast recharge my Tx and Rx batteries each morning using the Triton charger. My Rx batteries are all 6 volt NiMh, and my Tx battery is the standard 700 mAh NiCd that Futaba supplys in the 9CAP Tx. I was thinking about replacing the Tx battery with one of the newer, much larger...maybe 1500 mAh....NiMh types. I like the idea of having more reserve in my Tx for those days when I fly a lot...but what about when I fly only a few flights...will my practice of daily quick charging actually do my battery a disservice?
Thanks.
Jim

I use 1600 MaH NiMHs purchased at Radio Shack. I can go the entire day on one charge. I could probably go for the entire weekend, but haven't tried yet.

Jim your practice of "daily quick charging" is likely already doing your NiCd's a disservice in terms of life shortening heat. If you go to Nimh constant fast charging is even more threatening.

Hi!
Use 2300mAh -2500mAh NiMh Sanyo or GP cells and slow charge them over night (or for several days) with your old 50-60mah wall 220V (110V)charger..I have done this for more than 10 years. I use 1500 NiMh cells in my JR 388S transmitter. An old 50-60mAh wall charger works fine for these newer cells if you are prepared to charge for some days to have the cells full. I do have a fastcharger but prefere to slow charge my NiCad and NiMh cells.
Regards!

Try putting this post in the Battery Forum. Red can give you the straight scoop on how and why.

I use a 1600 Mah battery; look at hangtime hobbies at www.hangtimes.com for their NOBS Batteries; great product and price.

NiMH's don't like being charged at anything over 1C. Aside from that, I'd say you'll be fine.

I have 2500 mA Sanyo in my 9Z, fly a lot and charge it once at month, never problems.

As mentioned in several posts above, fast charging is not doing your batteries a favor. Both NiCad and NiMh will show signs of increased leakage with age and both have a rather pronounced self discharge rate (NiMh being the worst offender). While you can get by with fast charging as long as you stay withing the manufacturers ratings, you will get more life out of your batteries if you adapt a more conservative practice. If interested, check out www.powerstream.com/BatteryFAQ.html for some good info and advice on charging all types of batteries and why you do it that way.

2300 from Radical R/C is the only way to go, IMHO. I flew for a long time with the factory supplied battery packs - the 600-700MAH variety- always charging 'em etc, etc. Installed a 2300 and I'm charging about once a month- no kidding! Good price on 'em too, from Radical.
