I suspect that 72-144V would be doable, but we'll see!

Current control was a little tricky, but turned out not to be that bad. You just need a hall effect current sensor, and then a control loop to modify the PWM duty until you get the current that you want. That was the last 2 months of my life. I sort of wish I had it back. haha! just kidding. I think it would be the same idea for charging batteries, of course I have no idea what I'm talking about.
