LI-PO BATTERY CONNECTIONS

CHARGING BATTERIES

Each individual battery connector on the Parallel Board includes two holes which are cut through the entire board. One
hole is on the positive side (+) of the board, and the other hole is on the negative side (-) of the board. Securely connect
an output connector of your choice to two such holes on the board (see above diagram). Make sure the output lead’s
positive wire is connected to the hole on the positive side of the board, and the negative wire is connected to the hole on
the negative side of the board. It is highly recommended to use pre-assembled output leads with connectors to avoid
possible erroneous operation as a result of using poor quality connections. Again, make sure that NO BATTERIES are
connected to the board when installing the output connector.

To charge batteries, it is recommended to disconnect them from the parallel boards and connect them to the charger
individually. It is possible to charge batteries through the output connector which you connect to the board, but it is very
important that (a) the charger’s capacity value is set to the match the total capacity of the batteries which are connected
in parallel, and (b) the charger’s output voltage must also be set to match the voltage of the batteries which are connected
in parallel. See your charger’s instructions for further details.

It is highly recommended to cover the entire rear of the parallel board with an electrically insulative material
BEFORE CONNECTING ANY BATTERIES to prevent a short circuit condition from occuring. Electrical tape,
shrink tubing, or other forms of electrically insulative materials should be firmly affixed across the rear of the
entire parallel board. It is also a good idea to cover the unused holes on the front side of the board (where output
connectors can be attached) to prevent a short circuit from occurring as well.

When connecting multiple 3.7V batteries in parallel, the total voltage will still be 3.7V. Multiple 7.4V batteries connected
in parallel will have a total voltage of 7.4V, etc. Connecting batteries in parallel does not change the total voltage, but
does change total capacity and maximum output current to the ESC. NEVER connect batteries in parallel which do NOT
have identical voltages!!
