Wrong again. Sorry.
You are taking out four times that percentage out of just one quarter
of the whole battery. In four days it will amount to 20% of the
usable capacity (which is only really 500Ah) of one 12V battery.
Charging the whole battery will not restore balance unless you dump
an equivalent 98 Ah of charge out of the other 36 volts, making this
process at best 25% efficient and probably ending in tears.
