The delivery was next to the two batteries have a German manual. The design of the battery pack is the brand Wicked Chili corresponding black, red and white. The batteries have a capacity of 1180mA and 4,37Wh, in these batteries is Li-ion polymer battery. The battery life is indicated with approximately 120 minutes, which I can confirm after a few tests. Shop can these batteries with any conventional charger for GoPro Hero3 / Hero3 + batteries.
Conclusion:
What is there still a lot to say, at a price of 18 you get two top batteries, with a very good battery life and a practical strap for easy removal of the battery from the unit, this is very practical and makes this battery for me even better than the original.
