second, pausing for 2 seconds and then flashing three times, pausing for 3 seconds.
Short circuit protection: The green light repeats in a cycle of flashing once in 1 second, pausing
for 2 seconds and then flashing four times, pausing for 3 seconds.
Over-current protection: The green light repeats in a cycle of flashing once in 1 second, pausing
for 2 seconds and then flashing five times, pausing for 3 seconds.
Battery temperature is too high: The green light repeats in a cycle of flashing twice in 1 second,
pausing for 2 seconds and then flashing three times, pausing for 3 seconds.
Battery temperature is too low: The green light repeats in a cycle of flashing twice in 1 second,
pausing for 2 seconds and then flashing four times, pausing for 3 seconds.

The LCD display (3) show battery residual
capacity.
The color of the LC D (3) represent the
