How many Volts can I output to a Zumo Shield and be safe?

Currently the plan is using Li-Ion batteries (2x3,6v) to provide light-weight power to a Zumo Shield with a standard chassis and a Arduino Uno Controller.
We might also add more batteries for more amps but is 7,2 Volts okay?


You can use 2S LiPo batteries with the Zumo Robot by connecting the power leads to the charge port with no batteries in the battery compartment. You can see more about how the increased voltage affects the Zumo in this forum post by Jon.


Thanks for the quick reply!
