## Questions & Answers

**Q: Could i use this as a ups for a raspberry pi?**
A: From what I could tell on my board it has a delay of about 5-10 seconds from off to on. When unplugging the charging cable from the battery pack from both the usb powered option and the 5v.

**Q: What is the inside length of the battery housing? I want to use a protected 18650 cell with a 68.9mm length.**
A: Hi friend, the 68.9mm is too long for the housing.

**Q: Can someone clearly explain how this device works and its features? The instructions/manual is garbage and impossible to understand. Thank you.**
A: Slide -Switch appears to have the following use:

My V8 (dual-cell) unit has the slide switch (not labeled) and the push-button.  

Orient the board so you can see LED's and read stencil graphics, then switch is on the bottom-left of card.

(a) slide-switch LEFT ("position closest to the short-edge of the board") == AUTO power-down mode == unit will turn-off when there is nothing taking power from the USB port.

(b) slide-switch RIGHT ("position further from the short-edge of the board") == MANUAL == unit will remain ON until turned off or batteries too low.  

My unit does not auto-power up, but a single press of the button turns it ON, and double-press of the button turns it OFF.
Triple-pressing the button only glitches the power off/on and does not affect the LED's unlike what someone answered here.

**Q: can i hook a batterie bank to this to give this power? and dose it work with out the cells in it if i just have a batterie bank hooked to it?**
A: Treat this module as a standalone power pack. You need two 18650 batteries. Interestingly, Amazon sells some flashlights that include the batteries and a charger. It's a great investment.
