This module uses very sophisticated charging chip TP4056, the peripheral circuit is simple, tect perty, charge high accuracy.
The module is fully automated cessing machinery, SMD parts manufacturing, will be tested before each module high reliability.
The module current can be adjusted, as long as the change in the circuit board fixed resistors can change the output caused 100mA-1000mA, very convenient.
This module is used for single or multi-section parallel lithium lithium rechargeable battery, charging can take power from the USB port
Instructions / Notes:
It can only test current ammeter in series with the charging board 5V input.
The charging current of the battery capacity is best 0.37C, the capacity is 0.37 times, such as 1000mAH battery charge current 400 this is enough. Excessive charging speed effect poor, rushed over to the battery voltage out more!
The charging connector wires not too small too long. Such large connection resistance. Too thin, then rushed over to the battery voltage out more.
The best connection with the battery contact. Otherwise, the battery voltage is out of the red over the more.
If the 5V input voltage is high, such as 5.2 or even 5.5, will result in insufficient charging current 1000mA, it is normal. High voltage chip fever will automatically reduce the charge current, not to burn the chip. Chip at work about 60 degrees fever is normal. After charging current.
reverse input has no effect on the chip, but the output?Battery terminal?Reverse chip will burn, please note that buyers .
