I'm just suspicious a shock-reanimated battery holds enough power (=voltage) to bring us over the boot gap, and won't activate protection again just in no-time when we try to pull energy. That's all. Of course you can shockstart battery out of protect-mode, no doubt. But did you get a boot with such a bat? /jOERG
