TOPIC:

I have just finished building a Wild Willy 2, and I wanted a longer battery time as the 2000MAH battery it came with will only last about 10 minutes, I was wondering what battery would last longer but not put out too much power and make the Wild Willy uncontrollable. I was considering a 3800MAH but am not sure. Thanks in advance.

You can. Voltage are for power and ampers or milliampers are for the run time. Except for lipos wich are better for all.

Ah thank you!

you're welcome
