I have just taken delivery of my new EB70. I could not use my solar panel to charge it (it is a cheap one which says it cannot be used for lithiam ion batteries) so I used the 240v charger.
I could not get it to fill 100% - the top bar would not stay on after the charger was removed.
That was Friday. Today, 36 hrs later, it has discharged down to the bottom bar even though it has not been used.
what am I doing wrong???
