Just wondering why the larger receiver packs 1,000 mah and above could not be charged by the transmitter side of standard radio chargers. Most of mine list a charge rate of 100 mah for the transmitter and 50 mah for the receiver.

Thanks

You can! But since there are twice the number of cells in the transmitter pack you will need to connect two receiver packs in series. Or you can get a resistor from radio shack and simulate one pack by connecting it in series with the receiver pack and the charger. You will need a 50 ohm resistor 1/2 watt.

The capacity of the battery is not determined by the number of cells but by the capacity of the individual cells. Most receiver packs have 4 cells and some have 5. In the case of a higher capacity 4 cell pack, you cannot charge it with a standard charger because the change rate must be at least C/10 (C = battery capacity in mAH). A 1000mAH pack requires at least 100mA and the standard charger will be 50, 60 or 70mA for 500, 600 or 700mAH batteries. Look at the charger for the rating.

5 cell packs are another story. You not only need more current for higher capacity packs, you also need higher voltage (4 cells = 5V nominal, 5 cells = 6.25V nominal).

Say what? Of course you can use a regular charger, it's just going to take longer. For more information on this and many other subjects related to rechargable batteries, I suggest a visit to Red's R/C battery clinic: http://www.rcbatteryclinic.com/ . Particularly relevant to this thread is the article titled "All about Wall Wart Chargers".

A piece of advice.....if your going to play with the big packs, get a good charger like an AccuCycle Elite or a Triton.

I have 1100 and 2100 NiMh receiver packs. My futaba radio charger puts out 100 mah to the receiver pack lead, so the 1100 pack is right in line with that output. The 2100 takes a full day to charge on that lead. However I typically charge the larger pack with my Triton set on 200 MAh. I do the smaller ones on the triton at 100 mah sometimes.

Other times I just take a 2100 pack that is only partially discharged and put it on the 100 mah line from the radio charger to top it up.

No problems anywhere.

bps, 1000mah is not considered as high capacity anymore by today's standards on Rx/Tx packs. My Tx pack is 2300mah, and 2500mah is available now. Invest in a good peak charger that is capable of adjusting the charge rate from anywhere between 100mA to say 1A. I form and charge my packs at C/5, although I used to do it at C/10. The trick to good battery life is not to overheat it while charging. Do a search here and you'll find plenty of info of good peak chargers/cyclers available in the market. Make sure that it is capable of handling the battery chemistries you are using. Hope this helps
