All new, works good. Just half mm smaller than original - there is small gap between battery and drone, so its not fixed in place perfectly.. nothing hard to fix with small piece of both-sided tape. All batteries works good. With the adapter - i dont think all LEDs are showing me the truth, i think one is broken - its lighting immediately - without battery connected (other 5 holes are working good. Light turned off -> connect battery, light turns on -> when full, light will switch off). But super price for this product..
