Vive Tracker v1 and v2 are kinda bulky and last around 3.5h without extra batteries (which makes them even bulkier). There's some annoying bugs to them too.

Vive Tracker v3 are pretty decent at 6.5h battery and small size but they are quite expensive.

Tundras are cheaper, smaller and lighter than Vive Tracker v3 and come with a strap solution unlike Vive Trackers.

Then there's SlimeVR if you feel adventurous.
