Rc Car Help
Hello
If you still can get NiCd batteries (they have been banned because of the cadmium), it is worth to try. NiCd batteries are robust and forgiving. I don't know the current drain, but you might need special batteries that support high current. I think when you use types that can be fast-charged, you will be OK.
You may use fast-chargeable NiMh batteries (more mAh in the same package and easy to get). When you contact a RC model hobby shop or hobby electronics shop, they will definitely have suitable batteries for you.
One thing, older good fast-charge chargers for NiCd may not charge NiMh well (because of less delta-V near required charge termination point). Best thing is to charge them when they are empty with the recommended slow charge, it gives the longest life.
¡Espero que vas a encontrarlas!
