KD Spinner 3S 1600mAAh 3.6-4.8v Oil Pen Batt (Black)

Itnwas bigger than expected. 1600mah . Love the twist voltage settings. Feels heavy and durable. Can be charged with my Android charger is a plus. No issues yet. Will keep updated.

Bought two, both broke within a week

Loved the battery up to know...charged it once, used it till it died, charged it again and was using it and it is now just on, won't turn off. It blinks like it is turning off but the light just says on.. will be sending back promptly

I liked it ,,,,would buy another,,,,in fact I did

IT was exactly what I was looking for as a back up.
