Note
1>.2.1A is the max output current.It is not a constant current power module.Its output current change by load!It can not keep output 2.1A fixed.
2>.Old and new batteries can not be mixed.
3>.The battery cannot be reversed, otherwise the module will be damaged.
4>.Please check the battery voltage first. If the battery voltage is lower than 3.2V, the module will not work properly.
5>.Please input from Micro USB socket to activation module at first before connect battery.
Frequency Asked Questions
1>.What kind of battery to choose
Q:It is used for lithium battery.Battery can not be built-in protection board.The following battery is not suitable:Old battery;New and old batteries;Different capacity batteries;Different brands
2>.Why no output voltage
Q:Please input voltage from micro USB if there is no output from standard USB after connect battery.
3>.What is the conversion efficiency
Q:About 80% for new real battery.
4>.Why does the charger lose power or shut down automatically
Q:Poor battery quality, high internal resistance.You can change new battery or use better cable or output high current.It can change another USB output to connect to load.The two USB output:left one maximum output 1A;right one maximum output 2.1A.
5>.Why doesn’t the charge when charge up to 99%
Q:If it is a new battery,please discharged for the first time and then shutdown the module.Then recharging.
If it is the old battery,please discharged again and recharged once.If it is still the same, it is because of the large internal resistance of the battery and the inconsistent capacity.
6>.Why the percentage display is inaccurate
Q:Please discharged at first and then recharging.
