I’ve recently been in need of some extra batteries for my GoPro HERO4 Black edition. As you may know, the GoPro HERO4 uses different batteries than the GoPro HERO3 and HERO3+, so I couldn’t use my spare batteries I had for my HERO3/3+. I went over to Amazon and searched for the batteries. The official GoPro batteries are listed for $17.99. I then came across the Smatree battery replacement for the HERO4, and it was only $19.99. It includes two 1290mHa batteries, a 3 channel battery charger, and a USB cable. I immediately purchased it, and got it two days later using Amazon Prime. Amazon Prime gets you free 2 day shipping, it also includes instant video streaming (similar to Netflix), and a few other things for as little as $8.25 a month; and you get the first month free! Anyway, back to the review.
How long do they last?
Good question. I wanted to see exactly how long these batteries would last, so I setup a test to do just that. I set the GoPro up to shoot at 4K 30fps, with Protune enabled. These settings would stress the battery the most. However, these settings could also potentially over heat the GoPro, causing it to shutdown in the middle of the test. I turned off the heat in my apartment, and attempted the test anyway.
For this test, I was interested in recording four different times. The time at which the first battery bar disappears, the second, third and when the battery dies.
- First Battery Bar: 13 Minutes
- Second Battery Bar: 26 Minutes
- Third Battery Bar: 34 Minutes
- Dead: 61 Minutes
The Smatree 1290mHa baterries for the GoPro HERO4 last 61 minutes, when recording at 4K with Protune enabled. I was quite surprised to see the battery last another 27 minutes from the point at which the 3rd battery bar went away. Now you may wonder, how long do the original GoPro batteries last? I’ve done this test as well, and was able to achieve 66 minutes. This lined up perfectly with what the GoPro Companion app states. Just keep in mind, using 4K with Protune enabled is a worst case scenario. If you use 1080p at 30fps, you can expect something around one hour and thirty two minutes.
Being that the Smatree batteries are rated at 1290mHa, I expected to get much more battery life out of them. The original GoPro HERO4 batteries are rated at 1160mHa, and last longer than the Smatree batteries. But either way, you are still getting a great deal with these batteries. Remember, two batteries, a charger, and USB cable for $19.99. Buying official GoPro batteries and a charger would cost you about $68. Also take note that the original GoPro HERO4 battery is compatible with the Smatree 3 channel charger.
How long to charge?
I was also interested in knowing how long it would take to charge 3 batteries in the charger. I ensured that each battery was completely dead, and then I put in the two Smatree batteries, and one GoPro battery into the 3 channel charger. I plugged it into my computers USB port using the provided USB cable, and then waited. As expected, they didn’t all complete charging at the same time. The Smatree batteries finished first, and then the GoPro battery.
- Smatree Battery #1: 2 hours and 6 minutes
- Smatree Battery #2: 2 hours and 12 minutes
- GoPro Battery: 2 hours and 21 minutes
The LED on each channel will switch from red to green when the battery is done charging. The charger itself works great, and I haven’t had any issues with it yet. The only negative thing about the charger is the cheap feel, but nothing else.
Here’s a tip if you decide to travel with the Smatree GoPro battery and charger. If you are traveling and staying in a hotel, odds are there is a flat screen TV in your room. The TV should have USB ports that you can use to charge up your GoPro batteries using the Smatree charger.
