Black case 48v are older, probably in the 5 to 6 year range. I can't
comment on exactly when they made the change from black plastic to white
metal, but I just did a warranty replacement of old black plastic models
with new white metal ones. I would think paralleling would not be a good
idea, because of the age difference. As with lead acid, you probably
could get away with it, but I don't think they would charge and
discharge evenly. IMHO, those are too expensive to play with.

Is there a difference in the batteries in a white case vs. black case?
Are they compatible in terms of paralleling them?
Secondary question - I can't find the maximum number of these
batteries in parallel. Is anyone aware of the capacity limit?
