PAG PAGlink PL150 Series Instruction Booklet page 22

8.3 PAGlink PL150 batteries may be linked to combine
capacities:
1 battery = 150Wh
2 linked = 300Wh
3 linked = 450Wh
4 linked = 600Wh
Linking batteries also increases the maximum
continuous current draw capability to 12A.
The maximum number of PAGlink batteries that may
be linked has been limited to eight. If more than
eight 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, and prevents a transfer of charge between
batteries. As discharge progresses, 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. As long as the 'master'
remains connected, batteries may be added to or
removed from the stack (hot-swapped) in order to
achieve continuous running.
When not in use, batteries should be kept in an
unlinked state to ensure a lower self-discharge rate.
