8 Connecting to an External Battery
Extended Operating Time
Much longer battery operating time is possible when
connecting xPower300 to a larger external battery. For example,
an external 60 amp-hour battery will give approximately 3 times
the operating time of xPower300’s internal battery alone.
WARNING: 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. They contain acid,
which is hazardous if spilled. Wear eye protection and protective
clothing when connecting xPower300 to an external battery.
Connecting an External Battery
The external battery is connected using the Jump-Start Cable
as follows:
1. Connect the Jump-Start Cable red positive (+) clamp to the
positive terminal of the external battery.
WARNING: Connecting to the negative terminal can lead to a
battery explosion later in this procedure. The battery’s positive
terminal is identified as being larger in diameter than the negative
terminal. Do not proceed until you are sure you have connected
to the positive terminal.
2. Connect the Jump-Start Cable black negative (-) clamp to the
negative terminal of the external battery.
3. Plug the Jump-Start Cable into xPower300’s High-Power DC
Connector. Ensure this step is done last.
4. Disconnect the external battery in the reverse order of the above
steps before recharging xPower300. Use a separate battery
charger approved by the battery manufacturer to recharge the
external battery.
CAUTION: Disconnect the Jump-Start Cable from xPower300
and the external battery when xPower300 is not in use or when
there is no adult supervision.
