cheap, high power battery pack
« 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!!!
For whom the interrupts toll...


P.S. I've been inactive for almost a year... Don't give promises but I'll try to complete my tutorials. I'll let you know when..

Cheers!

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...
