9. Battery Protection Features
9.1
Over-charge Protection
Charging will be inhibited if the battery voltage exceeds a pre-set
level.
9.2
Over-discharge Protection
When the battery voltage reaches 12.5V, discharging is inhibited.
9.3
Over-current Protection
If a single 50Wh battery is subjected to a current greater than 8A
(10A for a 99Wh battery), but less than 15A, the output will be
turned off after 5 seconds. If the current is greater than 15A, the
output will be turned off immediately. In either case, the battery
display will be inoperative and there will be no voltage available at
the terminals. The battery can be reset by removing it from the load
and pressing the display button.
9.4
Thermal Protection
Software protection inhibits charging if the battery temperature is
below 0°C. Return the battery to the charger when the battery
temperature rises above 0°C.
Software protection inhibits discharging if the battery temperature
falls to -20°C, or if it rises to +70°C. The output can be restored
when the battery temperature becomes within the specified range
by pressing the display button.
A thermal fuse is incorporated within the battery construction as a
'backstop' protection device, and this cannot be reset. In the unlikely
event of this fuse operating, please contact PAG or your dealer.
9.5
Construction
The battery cases consist of high-impact ABS injection mouldings,
designed to protect the cells from impact damage. The battery has
been drop-tested.
The circuits are coated, making them resistant to electrolyte and
ensuring the operation of the electronic safety systems in the event
of damage to the battery.
Internal wiring is rated for high current and high temperature, and is
double-insulated for added safety and protection.
