12V UPS Extended Version

Overview

This is a 12V UPS extension version, currently used with my R3G and N100 routers .

I purchased the 12V 6A adapter (version 3S), which supports a maximum of 6A, sufficient for both the router and the software router. It
uses three 21700 batteries, which are very cheap to buy from used units on Xianyu (a second-hand marketplace).
I recommend using a 12.6V charger; otherwise, the batteries might only charge to 12V and then stop. Of course, using a 12V charger is fine, but the battery life won't be as long. For
any questions, you can join QQ group: 893808081.
Below are photos of the finished product.
