battery question

[CaptNitro]

Hey guys, I have a sc10 truck, was wondering which battery pack would give me the longest/fastest run time, a 6c 7.2V 4200 mAh NIMH or a 7c 8.4V 3600 NIMH battery, is there a big difference between the two packs and which one would give more/better run times?? thanks for the info

The milliamp rating (mah) is a guide to your runtime. This is your battery pack's capacity. Think of it as gallons of fuel. The voltage is power. More voltage (more cells) = more power.

so a 7.2 4200 mah will run longer, but a 8.4 3600 man will have more power, is the run time a big difference between the two vs the difference in power between the two???
