What cells does the pack use?

P42a cells
Check a P42A discharge graph
Check the 0.2A discharge graph here: Test of Molicel INR21700-P42A 4200mAh (Gray)
That’s for a single cell so find the voltage versus capacity-remaining at several points on the graph and then multiply the voltage by 12 and the capacity by 5 to get the pack voltage vs capacity numbers. You should be able to easily convert that to decently accurate percentages if desired.
Those numbers will only be valid for a pack that has not been used for at least a few minutes so it comes back up closer to its true “resting” voltage.

Excellent thanks, this is perfect information. I’d rather have the how to on this. Appreciate it!

Seen that referenced before but I’m not sure where to find it. It’s not listed in the app by default.

It’s on the firmware tab if you swipe up. It should automatically pick one of those 3 once you are connected. The bootloader helps the firmware to load when updating over USB/Bluetooth. It took me way too long to figure that out!

I don’t get any automatic selection (just like FW) it only lists generic.
Generic is an option and that’s fine to use

What downsides are there to running high motor amps? I’ve been keeping mine at around 75A since that’s what detection said, but I’m thinking about raising it. Thermals have been fine, neither the ESC or motor have ever gotten past 40 degrees I believe. ESC is the uBox v1, so there’s definitely plenty of headroom left in terms of power.
Y’all should really start doing this on a computer and not a phone.

I find lots of successes running my battery amps real low and my motor amps really high.
Both of those work together. I absolutely did NOT say just jack up your motor amps to crazy levels.
I HATE configuring vesc stuff on my phone, metr or vesc app, it all sucks lol

For me I usually run 50 battery amps per side and 100 motor amps, haven’t gone any higher though
Yeah phones are cool for telemetry or maybe an emergency fix but doing the entire configuration on them is for the birds.

I don’t understand why so many YouTube esk8 guides tell people to use a phone. Just boot up a PC and git gud.

My current settings are 75/75, thinking about possibly raising it to 100/75 or 120/75. I’ve noticed I max out the motor amps occasionally, so raising it should give better acceleration when I need it. 95% of the time it doesn’t go past 50A, so extra heating should be negligible.

I’ve setup a few boards with Freesk8 app without issue, super easy.
FW on the other hand, I will always plug into a comp.

Ugh with my build all sealed up and waterproofed, the only way to communicate with my VESC is through the metr dongle, either TCP or BT.
Usually TCP to the desktop version of VT is fine for 95% of things, but this new FW is throwing a wrench in my usual process
What specifically is preventing desktop use?
