Now the 18650 battery shield has been updated to V3. You can use this battery to shield power from many products like Raspberry Pi or. In this version the 18650 shield has a protection. The output current can reach 2A, I believe this will be a useful project.
What makes it special?
?Battery protection (overcharge or overdischarge)
? Micro USB port input
?Type A USB output
?0.5A current charging
?1 switch to control the USB output?5 ~ 8v input voltage
? 3V and 1A output
? And 5V voltage 2A output
? LED indication (green means, red means charging)
?3v output port X3
? 5V output port X3 be careful with “+” and “-“, you should follow the direction “+” and “-” on the PCB.
Note: If you put it in the wrong direction, the charging chip will be destroyed. This product does not include battery 18650
