2 Packs insta360 X3 Battery 1800mAh with 3-Channel Fast Charge Hub Bundle and USB Type C Cable Compatible with Insta 360 X3 Action Camera - 3.85V 6.9Wh (4 Items)

Great product, fast charging. Good value

These work very nice and are a great alternative to the standard Insta360 batteries, the one thing you can never know with these is how battery cycles affect the max capacity over time. You have to expect at such a lower price point they will degrade much more quickly, but I cannot assess that yet as I have not owned them long enough.What I can tell you is they fit very well, though sometimes I do need to wiggle them a bit to ensure they snap in and close all the way. The metal closure pins are a nice look and actually I prefer it over the Insta360 battery closures. However, I would never use these for any water based filming. I have had an issue with an Insta360 battery seal failing in past so would not trust any third party battery to keep the camera safe. These may hold up but I will not take that chance. These allow me to use these for terrestrial filming and save the insta360 for any underwater filming.The charge time seemed around 2+ hours with two in there charging and the same time. My normal use I get a bout 1.5-2 hours with my Insta360 batteries and these seemed to be roughly the same, maybe a touch less but could have been my usage so not an empirical test, but I suspect they are comparable with drain.The charger itself is nice, good build quality and was easy to charge and tell when everything was ready intuitively.So far no issues with the batteries and at 500 cycles should more than get my moneys worth at ~$30.
