Maintenance
Charging
Before operating the charger make sure to read and
understand the instructions that come with the charger.
Never attempt to charge a battery without first
reviewing and understanding the instructions for the
charger being used
Always make sure the chargers charging curve
meets the battery’s charging requirement; never
charge a visibly damaged battery; never charge a
frozen battery.
1. Connect the charger leads to the battery.
2. Make sure that the charger lead, both at the
charger and the battery side, connections are tight.
3. Turn the charger on.
4. Turn the battery on (if required).
NOT ALL CHARGERS ARE CAPABLE OF
CHARGING LITHIUM BATTERIES!
During system design CONFIRM that your chosen
charger is not capable of transient spikes that
exceed the published MAXIMUM TERMINAL
RATINGS of the battery
Discharging
• Turn on battery.
• Turn on load
NOTE: Do not discharge battery below
recommended minimum operating voltages.
NOTE: Do not discharge battery at rates greater than
recommended operating currents.
Storage
Systems should be stored out of direct sunlight under
the following temperature conditions:
System should be put into storage at 80% SOC and
checked monthly to ensure the system SOC (state of
charge) does not fall below 20%/ At 2-% SOC the
battery will self discharge in approximately 2 months.
Protection & Faults
• BMS (battery management system) generates faults
when maximum operating limits are reached.
• BMS sounds a buzzer when fault limits are triggered.
• BMS monitors the following information for faults and
warning:
• Cell module voltage
• Battery current
• Battery temperature
Faults & Corrective Actions
In the event of a fault the BMS (battery management
system) will sound an audible buzzer warning and the
system will shut off after a 120 second delay.
