Powering the VOXL 2 as a Standalone Computer
-
Hello,
I was wondering if anyone had insight on what battery to purchase for the VOXL 2 if I want to use it as a standalone lightweight mobile computer. I would ideally like the battery to weigh < 50g (the lighter the better) and would like for it to power the VOXL 2 for at least 30 minutes. I don't know much about batteries and so I would appreciate any help. Thanks!

Hi Thomas,
Thanks for your help. I was however looking for something much lighter, ideally under 50g. All of the batteries you sell are over 150g and are also designed to power the rotors (and so I assume are much more powerful than what is necessary to power just the VOXL 2). What specs should I look for if I just want to power the VOXL 2 and nothing else (other than, say, an attached 5G modem)? Thanks in advance for your assistance.

Hi @Mihir-Bala
You will need a 2S minimum to satisfy all the requirements of our power module: https://docs.modalai.com/power-module-v3-datasheet/
Then, you need to do the math to support a 30Watt transient on power up... which equates to a ~5amp burst at the low end of the 2S cell ~6.4V.
So, if you have a 1,000mAh cell at 2S, that will require a 5C rating.
If you have a 2,000mAh cell, you need ~2.5C rating, and so on...Hope this helped!

@Vinny yes thanks so much! I'll look into it.
