The 11.1 volts you saw was the voltage right after you took the batteries off charge. This is probably close to peak for your pack. All nicads will discharge slightly each day given no use and your .3 drop the next day in indicative of that. This tells me that you probably have a good pack in that transmitter. You need to read all you can on batteries, cycling and charging. It is really way too big a subject and I'm sure if you punch in "batteries" that you can get links to all sorts of thread telling you the great secrets of nicad batteries. With the new Li-Po cells coming out plus other new types of batteries make certain you get information on the types of cells you have. Futaba puts NiCads (nickel cadnium) cells in their stock packs. Other types of cells are Nickel Metal Hydride (NiMH) and the newest Li-PO (Lithium Polymer). This is an area where you just have to do the reading and if you have a question AFTER reading, then ask something specifically.

The nice thing about these forums is all you have to do is ask.....
