Today received my replacement batteries for GoPro HERO4 camera. They are from Smatree. I choose those over OEM batteries because of price (£19.99 on amazon) and because of good reviews (also on amazon). Batteries come with handy 3 channel charger.

1) Package and Contents.

Batteries came in nice small box, each battery was package inside smaller box for extra security, which is really nice. Then we have 3 channel charger with Smatree logo. 1m long mini USB cord- one of cheap ones with numbers printed on cable, but it is rather soft than stiff like the cheapest ones. Also there are user manual in english, small Smatree product catalog and thank you note.

2) Battery Life Time

The battery life time is better than OEM batteries. I was able to capture 64 minutes on 2.7K@48fps settings with wifi off, while OEM battery does about 5-10 minutes less.

3) Build Quality

Chargers build quality is great, simple to use, and have indicator lights while battery build quality is not the best. The plastic peace for battery removal tore off from battery at first try to pull it out. I had to cut sticker with blade to be able to pull it out from camera, but that is only poorly glued stickers and pulley string on battery. It just might be only one bad battery, peace is glued good on the other one. Stickers on battery are pretty bad, they got deformed when I put batteries inside GoPro. the plastic under stickers looks as good as on original GoPro battery.

4) Charging Speed

I was able to recharge 3 empty batteries from my computers USB 3.0 port in just 2 hours. From phone charger it took only 1h 15m to recharge all 3 of them. The best thing about this charger is that it can charge 1, 2 and all three batteries, no need to charge all of them. That is great for long filming sessions, you can take larger power bank and charge batteries on the field or just anything with USB port.

5) Summary

It is definitely worth to choose Smatree over original batteries, they have bigger capacity and comes with handy 3 channel charger. While build quality is not solid 10, everything else is.
