Do Edo-Tensei ninja have infinite chakra? It seems that people that were edo-tenseied were never out of chakra, would they have a limit on how much chakra they can use?
This is indeed one of the benefits of the Edo Tensei Justu. Their chakra reserves are always refilled, allowing them to perform tasks and cast justus endlessly without having to worry about running out


  A second benefit is the limitless refilling of their diminished chakra reserves that the reincarnated individuals have access to; they can fight eternally and perform ordinarily physically demanding or chakra-intensive jutsu without issue, knowing their current reserves will infinitely refill
