Hello i bought an rds 8000 2.4ghz i have a simple discharger, is it possible bypass the diode inside radio or i will damage the radio?

You would be better off to remove the battery from the radio to discharge it. If you bypass the diode in the radio and anything happens to the radio you will have voided your warranty by modifying the radio.

thank you ken but in future if i connect and disconect always wil i damage the female connector in the radio?

No. But how often are you disconnecting it? You shouldn't have to do it more than once a month or so, if that.

Ken

Just wondering why you would want to discharge the battery often enough to worry about damaging plugs...?

sorry my english i will explain all my procedure; when i finish to fly i discharge the battery and when are at low voltage with my simple discharger i charge 14 hours and i go to fly is it ok this procedure or can i charge just if i make 2 fly with my model ?
regards

There is no need to discharge the battery except for occasional inspection.

for example i go to fly with radio 10,7 volt i finish go home with radio voltage 10 when i will go to fly again have i to charge again 14 hours?

As long as you use the wall charger that came with the radio, after you finish flying for the day hook it up to the charger and let it go. Don't let it stay on the charger for more than 2 days in case it rains and you don't get to fly. Then if it has been unplugged for a day or two without flying plug it up for an hour or two.

If you are using the stock charger and the stock battery, 8 hours would charge it from completely dead. 6 hours is probably enough after a day of flying, but charging it overnight is perfectly fine too.

There is quite a variation between brands and models when it comes to how the wall wart chargers are set up. If you have a way to measure the current when the battery is being charged and know the capacity of the battery, you can make the following calculations. If the current is close to 10% of the capacity of the battery (example, a 600 mah battery and a charger providing 60 milliamperes during charge) you can safely leave the charger connected for 16 to 24 hours. As long as the charge current is about 10% of the battery capacity, this rule holds for Nickel based batteries (not true for LiPo or Pb based cells), an overcharge of at least 40 to 50% is desirable as the charging cycle on Nixx batteries is not very efficient and, at these low rates, will not damage the cells by overcharging them. Charging at higher rates can cause damage, especially if the peak detection circuitry fails. Heat is very hard on a battery so, if at the end of charge, you let the battery temperature rise much above ambient, you are sucking some life from the cells. The hotter they get, the more damage is done. A good source of the care of all types of batteries can be found at the following sources:
