4. Discharging
4.1
Mini PAGlink batteries can be discharged individually or linked. They
can also be discharged linked to PAGlink Gold Mount batteries Models
9306 (HC-PL94T) and 9313 (HC-PL150T). The batteries can be in any
state of charge. The maximum number of Mini PAGlink batteries that
may be linked has been limited to 10. If more than 10 batteries are
linked, the management system will shut-down the supply, and no
current will flow.
4.2
Where total continuous consumption is above 8A, two or more
batteries, of any rated capacity, should be linked. This will increase
the maximum continuous discharge current to 12A, provided the
batteries are in a similar state of charge. Sharing the current load
across multiple batteries prolongs individual battery life and provides
a better return on investment.
See Section 6 Battery Linking Features.
4.3
The batteries incorporate a precision, fixed, end-of-discharge cutoff,
set to 12.5V, as measured by the battery. This cutoff will only
operate if the battery capacity is less than 5%, eliminating unwanted
operation due to high current and low battery temperature.
4.4
The batteries incorporate a current limit of 8A for an individual
50Wh battery, 10A for an individual 99Wh battery, and 12A for linked
batteries of any rated capacity. Consumption above this for more than
5 seconds will trigger the over-current protection, turning the battery
output off. It can be recovered by simply removing it from the load
and pressing the display button, provided the battery still retains
some charge.
4.5
The batteries may be discharged within the temperature range -20°C
to +50°C, but for optimum performance, +10°C to +40°C is
recommended. The operating time will be shorter in conditions of
low temperature, and discharging will be electronically inhibited if
the battery temperature is below -20°C.
4.6
When the battery has been discharged at a high rate it will become
warm, and it is advisable to let it cool before charging it.
4.7
When not in use, batteries should be kept in an unlinked state to
ensure a lower self-discharge rate.
