Connecting Battery Banks
When your battery bank is connected in series, and you need
to increase the available amp-hours, you can connect two or
more battery banks together in parallel. This forms a series/
parallel battery bank.
To connect battery banks in parallel
1. Attach the negative (-) battery cable to the first battery
bank’s empty negative (-) terminal.
2. Attach the other end of the battery cable to the second
battery bank’s empty negative (-) terminal.
3. Attach the positive (+) battery cable to the first battery
bank’s empty positive (+) terminal.
4. Attach the other end of the battery cable to the second
battery bank’s empty positive (+) terminal.
5. To connect the battery bank to the Freedom Inverter/
Charger, see Installation “Step 4: Connect the battery
cables” on page 23.
Note: The load is cross-connected in the drawing. This
helps to balance the battery bank.
