3.7V polymer 18650 Lithium battery 5V1A UPS uninterrupted power module Reverse protection routing monitoring

parameter:
Enter: 5V1A or more
Output: 5V1A (MAX)
Battery: polymer lithium battery, 18650 lithium battery.(Suggestion capacity below 10000mA)
Enter: external power supply voltage is less than 6V.

Battery side: Anti -connection protection short -circuit protection is not broken during charging.

Output end: Only ordinary loads can be supplied, other power adapters cannot be connected, and they must be burned. The output short circuit is fine. Do not sleep when the load is small.

Volume: 33*15*4.5mm

Wiring port:

Input method: in+input positive level, in-input negative electrode,
Output method: OUT+output positive level, out-output negative,

Battery: B+ Battery positive electrode, B -Negative pole of the battery,

The indicator light (need to add it by itself): R+is an external power supply state. G+is the battery capacity indicator to display the battery capacity by flashing frequency. The faster the flashing, the more the battery capacity is, and it will automatically turn off when it is empty or when it is not charged.
Jumping line (J1) description: The power used to set the external power supply is a short jump line, and the external power supply current needs to be greater than 1A; when the external power supply current is less than 1A, it is necessary to disconnect and switch the 0.5A current power supply., Priority supply load, the remaining current is transferred to the battery and charging.

Note:
The circuit board will fever when charging, so the circuit board needs to be kept distance from the battery when assembling. Secondly, the battery is optimistic about the polarity. Do not connect it to avoid damage to the management chip. When the circuit works on the side, there is no short circuit protection. There is no short circuit protection.So as not to damage device
