Default Tx/Rx battery ma's

My radios use 9.6v/4.8v 500ma batteries for the transmitter and reciever respectively. If i were to use, say, a 9.6v/4.8v 1500ma packs instead, would I get 3x the run time?

I'm just not sure if the higher ma means longer run time, or more amperage out in the same time.

Any help appreciated!

I think you'll find they're marked as 500 mAh or 1500mAh. The "h" (hour) means that it is capacity (500 mA for 1 hour or 100mA for 5 hours etc) rather than just current (mA).

So yes, 1500mAh will give 3x the run time of 500mAh.

Good info.

I searched high and low to find the 600mah cells, and could have gotten 1800mah cells for an even cheaper price, but didn't know how the extra amperage worked.

It's not 100% linear with an increase in mAh's. Most battery manufactures should have some data sheets somewhere as to the effective mAh's you're gonna get out at various drain rates. It's usually close enough to the rated value not to worry about, unless you're into electric flight instead of nitro's.
