I'm a researcher in a lab that's starting work on some larger humanoid/quadruped robots as well as a quadcopter. Currently, we have several power supplies that have a max rating of 30V/30A and our modified quadcopter easily maxes out the current limit with only half of its propellers running. It seems like most power supplies are meant for small electronics work and have fairly low current limits. I think that I want to look for power supplies that are able to provide between 24-48V and higher than 30A for an extended period of time.
1.) Is this unreasonable or just expensive? 2.) Do most labs just connect PSUs in series to get higher voltages?
Thanks for the input.
