In the old Cortex system we had the battery expanders to add a second battery. Is there any way in V5 to operate on more than one battery? Or even on a power supply?

Thats very helpful, would at least extend the usage. So, there is no issue with it attempting to be charged while operating, even for high current draw in operation? This is for a non-competition application

Does it throttle them actively, based on present usage? Or does it throttle them pre-compile, essentially based upon the number of motors in setup?

Thanks much, we have 10 motors, but only 4 using decent current at a time.

The robot brain limits power at 2.5amp per motor and 20amp for the robot. If you use more than 8 motors at once, you will see a reduction in performance. Previously, the motor power would be limited if you placed more than 8 on one brain as it would place a lower current limit on the motor regardles…

[image] TriDragon: Thanks much, we have 10 motors, but only 4 using decent current at a time. You can still use 393 motors on V5, using the 3 wire ports connected to an Cortex expander. I bet you can find out how to code 393 motors relatively easily.
