On July 8th I received a package from Telesin with 3x GoPro Hero 5/6 Batteries, a Triple Charger and some screen and lens protector.
In my opinion the Triple Charger is a very useful GoPro accessory because you can use it like a small case for three batteries and you can charge them at the same time. The charger has three leds, one above each battery and indicates the status of the charge (red, orange and green).
The batteries works perfectly on GoPro Hero 5/6 and I suggest them to people that use a lot his GoPro on trips.
Each battery has 1220 mAh and the duration is very similar to the original battery branded GoPro.
I also suggest you screen and lens protector to avoid scratches that ruin your photos.
