HP Batteries; Medium Size

On some buttons, this will also restart the battery, and the LED lights will flash during startup. If this does
not happen, press
Start
(another little black pushbutton near blue backlight power button on top of
battery).
OLD VERSION ONLY
: The buttons only need to be pressed quickly and lightly; if they are
pressed too
hard they can “stick” and remain depressed –
this need a wiggle with a fingernail so they
spring back to their unpressed state (the latest battery version uses different hardware that does not do
this).
Repetitive Tripping
In some cases, the
inverter’s capacitors do not successfully charge up during the Pre
-Discharge
phase, and so will cause a trip (6: Short Circuit or 7: Surge Overload) after a few seconds every time
the battery is reset / turned off and on again. This is usually due to other 12V loads sucking current
that is intended for the inverter.
If your battery keeps tripping after reset / turning on, you may need to turn off / disconnect all other
12V loads until the battery remains ON when connected to the inverter without tripping. Then you
can turn on other 12V loads as normal.
Reset from Display Screen
You can press the Enter (right hand) button on the display screen to reset the battery. This is the
same button that cycles through the information screens on the Display when there is no Protection
state.
Reset from Battery
You can also press the power button OFF and ON again.
START Button - Hibernation / Shutdown
If the battery stays in the LVD for a long time, the power draw of the BMS, LEDs, monitoring screen
etc will eventually flatten the battery further to a state where the BMS will shut down completely to
prevent damage to the battery.
If the battery has been left in state #2 (empty) for a long time, the voltage will eventually get so low
that the entire BMS will shut itself down to conserve power and go into a hibernation mode.
In this state the power switch and reset button will have no effect, and no Status/Protection LED will
be shown. The Battery Charge Level / State Of Charge (SOC) value will also be forgotten.
To “wake up” the battery from this Hibernation mode you will need to connect
a charger, then press
the START button. After “waking up” you have 30 seconds to bring the voltage of the battery back up
to an acceptable range, or the battery will shut down into hibernation again.
SHUTDOWN Button
Acts like a reset button to revert back to the factory default settings.
Some older models of LBS batteries require pressing the Start button to wake up again.
