you would connect the the red wire from the positive terminal of the lower pack to the black wire from the BMS p- of the upper pack.
for the charger connections the red wire from the lower pack connection would be spliced to the hi side of the lower charger where it connects to the low side of the upper pack and the lower charger would connect the negative at C- on the lower BMS.
the high charger would connect with the red wire from the upper pack to the positive of the upper charger and the negative from that charger would connect at C- on the upper BMS. this makes more sense after editing.
assuming the chargers are isolated from ground. so each pack would charge on its on charger, and the HVC would protect it, and the LVC would shut off the connection if the BMS shuts down the mosfets.
i am sure a lot of people have done it, since i know a few here have.
