6. Battery Linking Features
The maximum number of 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.
Linked batteries form a network which allows communication between
batteries, ensuring that a safe protocol is followed under all
circumstances. The PAGlink management system elects the battery
with one or more connected to its front contacts to be the ‘master’
and ensures that this battery is always active (but not necessarily
delivering current). The system makes the most efficient use of the
energy available.
Fully-charged batteries discharge together sharing the current
demand and delivering power via a bus bar. This is intelligent linking.
NOTE: The rear battery does not fully-discharge first, followed by the
battery connected directly to the camera.
NOTE: The rear battery does not discharge into the front battery.
Batteries are electronically added to, or subtracted from the bus bar,
to deliver the current required. The status of individual batteries and
total run-time can be viewed via the battery displays. The total
available capacity is displayed automatically in the viewfinder/LCD,
when the camera has a compatible data system and has been set-up
to recognise the battery.
As long as the ‘master’ remains connected, batteries may be added to
or removed from the stack in order to achieve continuous running.
Batteries can be ‘hot-swapped’ regardless of their rated capacity or
state-of-charge. This is one of the foremost technological achieve-
ments of PAGlink. Current delivery will remain at 10A while there is a
large difference in individual battery capacity (>20%). The rear
battery will be prioritised to deliver power until the batteries are
within 20% SoC. They will then start to discharge together again,
and it will be possible to draw more current.
