I bought it for use with a blackmagic pocket cinema camera (bmpcc). Side satisfactions, batteries are nickelles: it works and it amounts to little things ready that comes with the bmpcc. The charger is convenient to him with many possible to supply power. Disappointment side, although I suspected, it's a charger and the charging time is long enough for batteries of this type. In comparison, bmpcc recharges the batteries more quickly. It is not dramatic, but it is to be taken into account if you want to reuse the batteries quickly. In the end, a good buy.
