charged batteries with one another.

When several battery modules are used, note the following:
● As many as six battery modules of the same type can be connected together in parallel.
● If different battery modules are connected in parallel, relay 2 flashes (battery defective).
No calculations with regard to charge and remaining buffer time are performed. The
battery modules are not charged, but buffering is possible.
● If more than six battery modules are connected in parallel, relay 2 flashes (battery
defective). No calculations with regard to charge and remaining buffer time are
performed. Charging and buffering, however, is possible.
