Please excuse my lack of knowledge
A question about batteries, I have recently bought a m03 mini which I am rebuilding, it didn't come with a power source so I am after some information. The batteries I have seen on various internet sites are listed as suitable for rc cars but come in various outputs, 2000mah, 3000 mah, 3300mah and 3500mah, the manufacturers are floureon and overlander and others. What is the difference, are they the same size and what is a good make, power output for the mini m03/ m05 for a reasonable run time? My previous tamiya's were back in the early 80's, I had a sandscorcher with the standard 7.2 volt power pack which you charged all night then drove it for 10 minutes the next day.
Thanks in advance
