You may find this thread interesting reading: http://www.chiefdelphi.com/forums/sh...ad.php?t=77837

Admittedly, they were planning to run 6 batteries in parallel, but you should still pay attention, because quite a bit of what they said will apply to your case.

Yeah your right. Its just like having a larger battery. But Of course with that you should always watch out and make sure that its fully charged. I remember hearing that if one cell of the battery is not fully charged (since it charges in cells, and they talked about this in that thread) that the output of all the other cells will decrease. And if you were to have a dead cell, charging would definitely be a problem. But i suppose those are all issues to attack when they happen (mainly the dead cell thing)

But I would love to see a video of that thing. It looks awesome. I know from our cannons we shoot t shirts, but we put a soda can in front of it and it just flew! Quite a site to see.

Please keep us updated on any revisions and any new videos you take after it stops raining

That looks really good! could use a little organization, but overall its pretty awesome! as far as the batteries go, on our teams t-shirt launcher we are working on, we have one battery for the electronics and one battery for all of the motors and compressors. This way when the motor battery goes dead we can swap it out without turning off all of the lights/sounds and electronics. We are also planning to have enough battery boxes on the robot for close to 4-5 batteries, this will allow us to quickly swap the connection if the battery goes dead.

Hopefully this will help you in your further designing of this robot!!
