Re: Why not recycle li-ion batteries and use them for OTG systems?

These are not AA size batteries. The size is 18650.

The battery pack can be built in any size, so If you need more amps just build a bigger pack.

I was just curious if somebody was interested in trying building a stand alone solar system with those batteries.

I would do it but at the moment I can’t have solar panels in the house where I am living.
