- 1 Month Manufacturing Defect Warranty
- Battery capacity: 3800mAH Maximum
- output current: 1.8A
- Output voltage: 5.1V plusmn; 0.1V
- Double USB output
- Standard charging current / voltage: 1.0A/5.0V
- Size: 8.5cm x 5.5cm x 0.9cm
- Weight: 35g
- It can last about 9 hours if only pi 3.
- The Lithium battery expansion board can be also used on cellphone.
- The working PMU (Power Manage Unit)can be only worked for charging mode or step-up mode at the same time.
- If the USB-A interface without any external load (like Pi), with 5V input voltage of MicroUSB, then the PMU enter charging mode. The PMU will integrate a current-limiting resistor with the external voltage, 5V voltage for Lithium battery, around 4.6V-4.7V voltage for USB-A interface.(The quot;ON quot; LED lights )
- The PMU would enter step-up mode without external 5V voltage. Under this circumstance, turn on the switch, USB-A interface can output maxmum 5V voltage, two USB-A interface can maxmum output 1.8A current. The PMU itself has current-limiting protection. it will be short circuit when over 1.9A current.
