Hi, I have a functional Librem 13 V2, thanks to Mladen, and to use it without Mains, I need a battery which plugs into the usual charging circuit. There are several options as to which battery I might choose.
I am guessing that it should be easy to acquire an external battery that changes the time of use by two or three times what it would have been if the the internal battery was brand new.
I see some batteries which are like ten pounds, a bit more than I would want to carry.
Also I am not knowledgeable in the sine wave of an external battery versus – actual AC mains.
Thanks for any replies.
