supply cannot have large instantaneous
fluctuations, otherwise the charger will be
damaged.

of connection, please be sure to follow the
recommended order.
1.The spark is a normal phenomenon when
connect with the power supply(The step①),
and the higher the input voltage, the greater
the spark; you can turn off the power supply
first, connect the step①, then turn on the
power supply to avoid the spark.
2. If connect in reverse order(step②, ③, ④,
⑤ ), It will cause a greater spark when
connect with battery.
