Title: cheap, high power battery pack
Post by: Trumpkin on February 09, 2008, 09:45:22 AM
i found this battery pack http://www.trossenrobotics.com/store/p/4300-6V-2-6Ah-NiMH-AA-Pack.aspx for 2.6Ah i think that's pretty cheap. maybe good for a small humanoid or something that uses a lot of servos.

It has a good discharge rate... 5A is good for 10 servos with med torgue... But handle with caution... You don;t want el chipo fireworks in your room!!!

in FIRST I accidently shorted the 12 volt, 12 amp battery, it made a bright blue arc and melted a small portion of the battery tab...
