Supplying Power to a Load
To use the SBP-1100e to power a DC load, first determine whether the fixed voltage provided by the SBP-1100e (e.g.
13.8 VDC or 25.3 VDC, etc) is appropriate for the load, and that the power demanded by the load will not exceed 300
watts on a continuous basis. If continuous power in excess of 300 watts is required, consult 1100 Energy.
Connect the SBP-1100e power output jack on the right side of the unit to the load using the provided cable or other
approved cable. A short output cable terminated with ring terminals, provided by 1100 Energy, may be used to con-
nect with another, longer, user-provided cable if appropriate. User-specified extension cables should be of a wire gauge
adequate to avoid an excessive voltage drop in the extension cable.
The panel display may be controlled to show the voltage, current and an estimate of the remaining battery pack charge
as a percentage of the charge capacity. The SBP-1100e may be used to provide power to a load while the battery pack
is being charged.
If the SBP-1100e becomes fully discharged, and the output cuts off, a small amount of residual stored energy will
maintain functionality of the user interface for one hour or more. This feature is partly for user convenience during at-
tended operation and testing, and it also keeps the serial control and monitor interface functioning. If no new charge is
added after the output cuts off, the user interface will cut off as well, after 30 minutes, and the unit will then appear to
be totally dead, with no power output, no display, and no response to button pressing. The SBP-1100e is in hibernation.
However, the user interface will come back to life within 3 seconds after external power is applied, and after a suitable
period of charging, the SBP-1100e battery pack may again be used normally. In the event that charging power is applied
after the output has been cut off, the state of charge must rise to about 15% before the output will be turned on again.
Power Output ‘On’ and ‘Off’ Control
To check the output voltage and current, press the ‘SCROLL’ button on the Control Panel repeatedly (slowly) until the
second line of text of the LCD display shows the output voltage and current, for example:
Out 13.8V 00.0A
This display will persist for eight seconds, during which time the ‘SELECT’ button may be pressed to toggle the power
output ‘on’ and ‘off’. That is, if the power output is ‘on’, pressing “SCROLL’ once will turn it off, and if the power output is
‘off’, pressing “SCROLL’ once will turn it on. The change in output voltage and current resulting from turning the output
‘on’ or ‘off’ will not appear immediately on the LCD display, because the display is a frozen snapshot of the state exist-
ing when the ‘SCROLL’ button was pressed. To see the new output voltage and current, again press the ‘SCROLL’ button
repeatedly (slowly) until the new data is displayed. Note that if there is no load connected to the SBP-1100e and the
power output is turned off, it may take 30 seconds or more for the indicated output voltage to fall below one volt, due to
stored charge in the output regulation circuit. If a load is present, the output voltage will instantly drop to zero when the
output power is turned off.
The SBP-1100e has a very high power and energy density. Mishandling may present a risk of fire or explosion. Exer-
cise common sense precautions when handling, transporting, or testing. DO NOT OPEN the battery pack case and
replace individual cells or modules. Usage should be carefully coordinated with 1100 Energy to ensure proper opera-
tion and safety.
