Default Re: Best lithium setup for Navitas 600/5kw?

I don't have any comment on drop in lithium packs since I personally would not use them (it is mainly my preference), but I do have a question that maybe the Navitas guy can answer or someone else perhaps already asked them the question.

Assuming Your battery pack has enough current discharge to provide the nominal voltage needed under load to prevent a "slip" on the AC motor, is there any benefit to going high voltage?

I see a lot of folks making inferences that going from a 51v to a 72v lithium pack would increase the speed but on AC motors the speed is related to frequency and number of poles.

Obviously increasing the pack voltage would allow for a smaller AH pack that delivers the same energy, but it seems that increasing the voltage by itself on a otherwise well matched system would be a waste of money.
