A 6V Power Circuit

Hello community,

I have created a device which is a complete 6V powering system. It can also be used as 6V UPS.

It has the following features:

• Over charging protection
• Reverse protection
• Over discharging protection
• Indications
• All sort of polarity guidance like +/- signs at the back

Input voltage: 6 - 9V

Output voltage: 5.5 - 6.2V

I wanted to hit the store. Just wanted to know if this looks good, are there any demands and the device is worth some bucks...

Thanks!
