great to see another episode. i really appreciate all the insights and the open approach to your project. your cubesat series has slowly become one of my favorite things to follow to youtube
One tip: you will need a batttery balancer IC for the cells in series. Parallel cells of around the same capacity will share charge so they don't need balancing and can basically be treated as one cell, but series cells will need a balancing charger.
Yes, that's definitely on the roadmap for v2! I want to get the basics right first, so for the moment (up until the suborbital balloon flight next year), I am just using equally charged cells. Are there any balancer ICs you can recommend? As usual, there is a staggering variety.
@buildacubesat I don't have any recommendations, but projects like OreSat, PyCubed, and PROVES probably use some useful ICs (and they've already been tested in space).
@Build a CubeSat PGB1010603MR has a Clamping Voltage = 150 V. This could be a problem if for example voltage is 70V. No problem if voltage is more than 150V. Why did you select this device?
Hi! Thanks for bringing this to my attention, that's really helpful. I have some of them at hand and didn't check the specs closely enough. I don't expect anything above 24V anywhere on the board down the road. Is there a 0603 device you would recommend?

Thank you so much, this means a lot to me! :)
Building REV 2 for my EPS set to launch next year. Thanks for the valuable insight into your design
Awesome! Just watched your NASA ASCEND video, beautiful footage. Are you going to document your next launch too?
Electronics 😍 Keep that Awesome stuff coming Sir
Will do! 🫡
