Danzo was able to change Shisui's KA from recharging over the course of a decade to one day with Senju DNA. I guess there is no proof that it helps Obito also seeing as it hasnt been directly stated but im pretty confident that explains why he can use it so much and have no effect on his eyes.
EMS basically removes the effects of stress, burden, and more chakra consumption from the body. Which would explain why Obito shows no fatigue whatsoever. I don't think it has anything to do with senju DNA.
