6.3
Battery
Bank
Setup
A second (or third) battery can be connected to the ToughPower to
create a Battery Bank
.
With the addition of a second Battery
connected in parallel you will be able to either extend the time
between charging, or power more devices. The additional Battery
must be the same Type
of Battery chemistry as is fitted in the
ToughPower otherwise you risk damaging the Battery as the
Charging
Voltage
is
specific
to
the
Battery
Type!
You will need to make a small cable with either Ring Terminals or Alligator Clips on
both ends to connect to
the terminal posts of both Batteries.
Remember: connect Positive to Positive, & Negative to Negative.
Keep
the
cable
as
short
as
possible
and
we
recommend
using
AWG6
sized
cable.
This method of connecting the two batteries directly to the terminal
posts allows the ToughPower to provide the same
Low Voltage
Shutdown
and
Charging
Protections
to
the
second
Battery.
Refer to section
Battery Capacity & Condition Setup for instructions
on how to set the “
Battery Bank
” option on the ToughPower LCD
Screen.
Note: When the
Battery Bank option is setup correctly, the
time prediction and
battery percentage
functions are disabled. For monitoring, the Battery Voltage will continue to be displayed on the LCD
Screen.
Note: Take special care to attach the Battery Terminals correctly! It must be
Parallel Connection - Red to
Red (Positive to Positive), and Black to Black (Negative to Negative). Incorrect terminals connection will
cause
permanent
damage
to
the
sensitive
electronics
inside
the
ToughPower.
Warning:
You
cannot
make
a
Series
Configuration
to
increase
the
system
Voltage!
The
ToughPower
is
a
12V
system
only.
6.4
Charging
a
Boat
Battery
A variation of the Battery Bank Setup is possible whereby an external
Battery can be connected and charged by the ToughPower, and then
disconnected after charging. For example: Charging a recreational
boat
deep
cycle
Battery.
Note: This battery must be the same Type
of Battery chemistry as is
fitted in the ToughPower otherwise you risk damaging the Battery as
the
Charging Voltage is specific to the Battery Type!
The Battery
must have been removed from the boat/vehicle before connecting
to
the
ToughPower.
Using the same or similar cable as described above in
Battery Bank Setup
, you will need to make a small
cable with either Ring Terminals or Alligator Clips on
both ends to connect to the terminal posts of both
Batteries. Remember: connect Positive to Positive, & Negative to Negative. Keep the cable as short as
possible
and
we
recommend
using
AWG6
sized
cable.
