Systems should be put into storage at 80% SOC and checked monthly to ensure the system SOC does not fall below 20%. At 20%
SOC the battery will self discharge in approximately 2 months.
7. Protection & Faults
• BMS 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:
1. Cell module voltage
2. Battery current
3. Battery temperature
7.1 Faults
In the event of a fault the BMS will sound an audible buzzer warning and the system will shut off after a 120 second delay.
When the operating conditions are within acceptable ranges, the battery can be recovered from Fault by pushing the ON-OFF
button.

• Stop discharge or charge
• Leave the battery to cool
• Stop discharge or charge
• If charging stop the charge
• Do not discharge the battery. Any
discharge current detected will force
the battery into Low Voltage Fault
• The user can charge the battery in
Low Voltage Recovery
• If no charge current is detected
within 2 minutes the BMS will turn
off the battery
• Reduce current
• Stop discharge
• Charge the battery
