With the proper use of a battery discharger you can increase the life and performance of your batteries. This simple and inexpensive discharger is all you need.

Here's How:
Construct a discharge device by attaching two wires to an automotive tail light bulb.
When you are done running your car, attach the discharge device to your battery pack.
Watch the bulb, when it starts to go dim, remove it from your battery pack.
Ideally, you should only use your battery pack once per day, if this is not possible, make sure it is fully cooled before charging it again.
Tips:


Always discharge your batteries after use.
Never charge your batteries if they are still warm from a previous use.

Wow! this is cool I didn't think of this.
If I used 2 lights will it be better/worse?
Also this sounds like it's to drain the 4 pack in the reciever box for the servos, can I drain a larger amount than 4? As in make the connection to the light a double ended connector and stuff like that? To drain a larger amount of batteries at a time.
