Yes, You can. You can even make autoboot battery that boots flasher only if you hold button you selected when converting battery and if you dont press the button PSP boots like with normal battery.

Yes you can if you're careful. Why do you want to downgrade to 1.50? You can check your current firmware by going to System settings and looking at system info. If you're below 6.37 OFW you can downgrade using Hellcats, see the PSP stickies for more info.
