the Batteries part 2:
rescued the most discharged batteries using parallel charging, it
is time to prepare the bulk of the batteries to be assembled as
a pack. The goal is to have all the batteries fully charged before
assembling them as a 385 volt pack. This way, when we start cycling
them (discharge and charging them), all start equally charged.
parallel charging six at a time for 48 hours will take a while,
we start sorting the batteries of about equal state of charge (based
on resting voltage) and charging them as 24 volt series. With 180
batteries, it is easy to find 12 batteries within a couple of hundreds
of a volt of each other.
