FUSE can sensorize the circuit current and temperature. The fuse cannot be recovered after melting. It must be replaced in time. It is more troublesome, but now there are self -recovery FUSE fuses.

　　Under the condition that the ambient temperature is 20 ° C and the self -re -fuse reaches the heat balance, the current on the line is 100 % flowing through the self -re -fideline.

　　① The battery cannot be charged

　　If the power is charged, it can be divided into the following reasons: the charger is overwhelmed or the charger fails; the maintenance board maintains the failure or maintenance board failure;

　　Find in order to deal with the above bad phenomena: whether the charger is connected, whether the battery pack charging positive and negative plug is reversed; the restart of the electrical appliances to relieve the maintenance board maintenance, measure the driving voltage of the MOS tube of the MOS tube; Essence

　　② Short battery life

　　The battery pack was quickly discharged when used. The reasons for this situation were: lithium -ion batteries were not filled with full power; single series voltage capacity was large; the battery pack micro -short circuit or the battery pack self -discharge caused the battery pack to be just charged just charging. The amount of electricity is consumed.

　　For the above bad, it can be handled by charging or replacing the battery cells from the beginning.

　　Amendment method: After the discharge is 10.5V, the bulb is discharged for 1-5 hours. Then there is the activation device to activate the correction. In this way, there may be correction, but in a heavy case, new ones can only be replaced.
