Use matters:
1. The motherboard received first connected to the charging head test, look at the display status, to confirm that there is a display and then assembled due to the lack of batteries, the display brightness will change is normal!
2. Normal application of the battery must be welded (wire twisting will be insufficient power supply) battery reverse motherboard must burn dry million attention. Wire as thick and short as possible. If the charging voltage immediately rise or discharge voltage immediately drop, that wiring problems or battery performance is not enough!
3. If you find that can not be full or can not be discharged, this and the wiring of the battery internal resistance protection board have a relationship, check the wiring, and whether the voltage of each battery is the same, to ensure that the battery is good, if the battery is connected to the battery on a full charge, plug in the phone can not be discharged most of the battery aging scrapped!
4. connected to the battery found not working or not output check the battery voltage is used within the range, the battery string number has not been set to the right, the battery type is right. The board must be burned reverse burn IC will have traces, only the reverse connection will appear in this case!
