Power supply system in the new Pimax 8K controllers. "АА or ААА vs built-in batteries"

What kind of power system will be in the new controllers?

I propose to get away from the built-in rechargeable batteries, which have few hours of operation, and this is very small, compared to capacious AA-type external batteries.

For example:

  • in Oculus-touch the cheapest alkaline batteries were enough for 12-14 days of daily work for 3-4 hours a day.
  • In controllers HTC-Vive built-in batteries work only 6-7 hours on one charge, and after that they have to charge for 2 more hours. And, in time they will lose their capacity.

This is an unacceptable time to work in my opinion, not optimal
In the oculus-touch it was possible to forget that about charging for controllers for 1.5 - 2 weeks.

Please attach a vote between the choice: AA - batteries vs built-in batteries.


Rechargable AA or AAA batteries.


Make hear your thoughts regarding powering the controllers!

  • built-in batteries
  • AA or AAA ‘removable’ batteries

What about removable batteries that also offer the option of using rechargeable batteries that can be charged through the controller?


But does not this make it heavier?

I really liked the locking mechanism on the oculus-touch, where you insert one AA battery, and the lid on the magnet itself came into the controller.


Very handy thing :slight_smile:

You have my vote.

That´s is the best option.

Removable are good for replacement needs but can also add bulk.

With the usb-c or external usb battery one could simply tether controllers to headset or use usb bank in a batman utility belt. :beers::smirk::+1::sparkles:

Generic Quad copter 600mAh lipo, easy to buy and have a pile charged up, rechargeable AA are too naff. The oculus controllers sip power because they are mostly driving an infrared remote control, VIVE controllers are mini PCs.

Actually a 900mAh 14500 Li-ion Rechargeable Battery would be awesome.

Those batteries are huge 16650 if those are the ones i think they are.

Yeh i edited it sorry 14500 are the same size as a AA

I think they will not work, the current is too high 3.7.

Here are the best rechargeable AA batteries: Eneloop Pro 2500

2 aa would require too much bulk. Batteries can have voltage regulated/stepped down.i have a variety of aa 2500mah.

2 AAA rechargeable still bulky but beleive caps out @ 1000mah still on average almost twice capacity of controllers.

I prefer li-ion batteries, I don’t understand the battery complaint at all from anyone, AAA batteries just means more hassle, my Vive wands are always charged and in the event I would forget I can just charge one for 10 minutes or so to get enough for whatever game I want to play.

In my opinion, 1 AA 2500 mAh is enough for one controller. in the Vive-sticks are generally 960 mAh batteries.

And to me the most usual alkaline battery 1 piece in 1 oculus-tache enough for almost 2 weeks :slight_smile:

And my Vive wands lasted for a year since I could just plug it into a usb.

I have AAA batteries in my headphones and they are super annoying and cost a bunch, I wish I could just plug it in and charge whenever I’m not using it instead.

Vive-wands only work for 6-7 hours and say hello to the usb-cord for 2 hours.

Batteries AA Eneloop Pro 2500 have a canceled capacity and low self-discharge in the course of many years. They are eternal almost. More on you no need to spend on batteries, buying a kit + charger. All economical people do this :relaxed:

I could be wrong but
3.7v * 960mAh = 3552mWh
1.2v * 2500mAh = 3000mWh
The Oculus controllers are a lot happier @ 1.2v than the wands microcontrollers, though who knows i’m no expert?

Yes, my point, AAA batteries take effort, you need to take them out have spares, buy charging stations etc, they are terrible.

I have never played seven hours with no break, and even if you do run out you have a 15 minute break (which you’ll need anyway) and you are back to playing again. I’ve run big events with the Vive wands and battery has never ever been an issue that I have ever even thought about.
