I prefer to charge at 0.5 mah (with external LiPo charger up to 4.10V) as I have 3 LiPos and I don't care about time, but less mah, less stress, more life for the battery.
Hello. I also had the same problem with the Hadron Pro. I inadvertently installed the SP45 and noticed the same problem as you. Now I have reinstalled the SP33.2 INT hoping to fix and hoping that the timing is not locked at 12 hours. Fingers crossed. Unfortunately I have not read that very small notice inside the box and I read franticseven's post just now. Pity
