Appendix B
Extending Operating Time
Longer operating time can be realized by connecting ElectroMate to an exter-
nal battery. The external battery will combine the Ampere Hour hour ratings
of connected batteries. If your original configuration contains an 80 ampere
hour rated battery, connecting another similar battery will provide 160 am-
pere hours of capacity. This at least doubles the run time of your unit before
the batteries must be recharged. The user should be aware that with two
similar batteries connected, (one inside and one external) the charger will
take twice as long to recharge as with a single battery. There are two methods
to connect to an external battery: One is to use the Jumper cables; the other
way is to direct wire to the high current posts. Use the jumper cables for
extending runtimes of lighter temporary loads. Use the direct wiring method
for extended and more permanent higher power loads.
WARNINGS:
Never use the jumper cables to connect to a battery that is not stationary
– vibration can shake loose the cable clamps. A moving vehicle or boat
can shake loose connections. Never operate ElectroMate or an external
battery without securing them first. Cover any battery terminals.
Vector Manufacturing has #2 AWG cable sets that will ease connection to
an external battery. These are equipped with a fuse, fuse holder and ring
terminals on the cable ends. The cables are easily connected between the
external battery and the high current posts. The only cautions are that the
high current post connection polarities must agree with the battery polarities.
The red cable must connect the red cap post and Pos or (+) battery terminal.
The black cable must connect the black cap post and Neg or (-) battery
terminal. Make sure all connections are tight. If you require a cable set,
contact Vector Technical Support at 866-584-5504.
