4.4.1 General advice for interconnection of batteries
4.4.2 Parallel connection
Connect Power 26-104 in parallel, as usual, by connecting positive and negative poles
to each other. The following figure shows parallel connection of two batteries (1S2P
connection). In the same way, several batteries may be interconnected in parallel.

the same state of charge. Thus only use same type of batteries for
interconnection (same capacity, age, manufacturer and state of char-
ge) and fully charge every battery separately in the charger before
their interconnection.
Differences in state of charge may induce extremely high compen-
sating currents overcharging cables and connectors or battery itself.
In extreme cases even fire or injury may be the result.

and negative pole of second battery.
The following figure shows serial connection of two batteries (2S1P connection).
