Honestly how could Batman compete realistically with a person that took on the JLA and Superman himself. Ummm...those arn't chi attacks, those are martial arts moves. Show me where he has healed himself with chi
Regardless if he took Solomon Grundy down or not, Batmans taken down class 85 to 100s before.
A few of his rouges come to mind like Bane, Killer Croc and Clayface, all are top tier in strength.
Even Supergirl and Superman are high in strength and he's beat them, yes he has the K ring, but that would probably still leave them pretty high in strength.
Batman's trained in 124(yes it may be silly that he knows that much, but he does) martial arts he's got to know chi attacks.
Kung Fu has tons of chi based moves and hes mastered that.
One would only assume that hes using them well fighting h2h.
I know it doesn't say that he does use it all the time, but common sense would say he does other wise it would be ridiculous for him to be able to hurt them.
As far as him healing himself, I haven't seen him do it, but I'm sure he does something similar to what Daredevil said he learned from the hand.
Which focusing the pain away.
There are techniques in martial arts that can let you heal yourself though.
Batman knows 124 martial arts so I'm sure he was taught along the way.
