Chart 2. Discharge Rates for two Battery Packs Daisy-Chained together.
When the remaining battery capacity is estimated at less than 10% the red lamp will flash. This is a good
time to find an external power source (i.e. a 2
nd
BATTERY PACK unit or an external power source), or be
prepared for the device operations to end abruptly.
Units may be “daisy-chained” to increase the operating time. It is recommended to not cascade beyond two
BATTERY PACK units. When “daisy-chained”, the BATTERY PACK that is not connected to the
Logicube device will discharge first, while simultaneously charging the 2
nd
BATTERY PACK unit. This
operation allows for additional BATTERY PACK swapping without a power interruption to the device.
As the battery discharging “personality” changes (time, number of discharge, temperature, etc.), the
BATTERY PACK unit automatically learns the current battery characteristics with each charge and
discharge cycle.
Deep Discharge
Leaving a Logicube device power on the Battery Pack indefinitely, with no external power, will cause the
battery to go into a “deep-discharge” state. The Battery Pack units can recover from this state (during the
next charging cycle), but the overall battery life has been reduced. Also, the Power Gauge might be
affected as it now represents the total battery capacity, not the useful battery capacity. This Power Gauge
problem will correct itself with the next full discharging and full charging cycle.
NOTE
: The Battery Pack unit should be recharged at least one every 3 to 6 months, to prevent the battery
from entering a “deep-discharge” state.
