Hi all.
First of all, let me say that I am not an engineer, only an electronics hobbyist "wanna be", so please bear with me...
I want to build a mini ups to ensure uninterrupted power for my router and fiber ONT during grid power outages.
The battery pack will be assembled from 18650 lithium batteries;
It must have passtrough function, so when AC power is on and the battery is fully charged the power goes straight to the connected devices and when AC power fails the battery pack will provide power for the devices without interruption;
It should have 2 DC output connections with 2 amps and selectable voltage (9 and 12 volts) and one USB port (5 volts, 2 amps).
Again, I am no engineer, so I need a simple schematics and the list of components needed to buy and assemble everything together.
Any help or advice will be apreciated.
Thanks in advance.
