When charging, the resistors are positively biased. We can\nuse the PWM to control the signal.  The opamp must be\nengaged.\n\nWhen discharging, the resistors are negatively biased. \nThe mosfets will always be on. If a battery shorts, then it\nwill be forced off by virtue of pulling the resistor up. \nWhen discharging, all outputs from processor should be 0.\n
