Hi. Please explain to me what is the problem with my battery charger for Ph 2 V+ ???
Yesterday I put battery to charge and and start to charge ok.
Than after few minutes charger starting blink red and battery not charging. After I disconect charger from wall socet still red is blinking but slow and slow.
After few hours, I try again and charger start to charging.
BUT, it takes 8 hours to charge the battery. I put next battery - 10 hours. I put the third battery - after 4 hours still blinking 1 green light on battery. After 6 hours blinking 2 green light on battery.
What is the problem???
I bought the phantom 2 V+ in June.

Since it's doing the same with three batteries it's fairly certain something is wrong with it.
They aren't terribly expensive to buy new.
I would do that rather than try a warranty claim I think.

Ideally borrow one to test from someone nearby?
