Auto calibrate wasn't created by dr_frost_dk, AFAIK, it's from joerg_rw. Instead of using charge*.sh, you could also do the same with kernel-power and Pali's bq2415 module (charging one).

Hoever, no matter of method, I don't see how *charging* with script/module as opposed to BME could help You with vdq going to 0 during *discharging*.
