Brother for the first time to play ups would like to ask about this connection is wrong. I am connected to the uninterrupted power supply on the spark, what is the problem ah?
At this time the connection method is short-circuited, so take a fire.
Pay attention to the operation do not short-circuit, large capacity battery discharge capacity is very strong, short-circuit can be red instant screwdriver.
This can not be seen, you use a multimeter to determine whether the battery voltage is consistent with the design.
