Connecting to an External Battery
You can extend battery operating times by connecting the
XPower Powerpack to a larger external battery.
For example, an external 60 amp-hour battery gives
approximately three and one-half times the operating time of
the XPower Powerpack internal 20 amp-hour battery.
To connect the XPower Powerpack to an external battery
using the jump-start cables:
1. Connect the jump-start cables to the Jumper Cable Port
on the left side of the XPower Powerpack.
2. Connect the red positive (+) clip of the jump-start cables
to the red positive (+) terminal of the external battery.
3. Connect the black negative (–) clip of the jump-start
cables to the black negative (–) terminal of the external
battery.
Note: Leave the thumb latch in the open position for
storing to relieve pressure on the internal mechanism.
WARNING: Acid spills
Use a sealed, non-spillable battery for indoor use.
Common auto and marine batteries are not suitable for
indoor use unless their fumes are vented outdoors.
Common auto and marine batteries contain acid, which
is hazardous if spilled. Wear eye protection and
protective clothing when connecting the XPower
Powerpack to an external battery.
