represent battery failure information
until the failure is remedied. Details of failure information are shown as below:
Under-voltage of single cell battery: The green light repeats in a cycle of flashing once in 1
second, pausing for 2 seconds and then ashing twice, pausing for 3 seconds.
Over-voltage of single cell battery: The green light repeats in a cycle of flashing once in 1
second, pausing for 2 seconds and then ashing three times, pausing for 3 seconds.
Short circuit protection: The green light repeats in a cycle of ashing once in 1 second, pausing
for 2 seconds and then ashing four times, pausing for 3 seconds.
Over-current protection: The green light repeats in a cycle of ashing once in 1 second, pausing
for 2 seconds and then ashing ve times, pausing for 3 seconds.

pausing for 2 seconds and then ashing three times, pausing for 3 seconds.
Battery temperature is too low: The green light repeats in a cycle of ashing twice in 1 second,
pausing for 2 seconds and then ashing four times, pausing for 3 seconds.
