Include a voltage divider so battery voltage can be measured directly, with support for up to a 6s battery.

Stretch goal is to add balance charger but this will probably be too expensive.

oops..

Add some 3v3, 5v, vin, and gnd pins in a cluster somewhere so peripherals can more easily access power and ground

Safety is number one priority.

Not sure of the value since this board is hangry for power.

The green ones are ugly and I'm vain

5V isn't actually used by any onboard devices so it's fine if it isn't perfectly stable. Retain lreg for 3v3 line.

Use DMT3006LDK-7 instead of NVTFS5C680NLTAG

30V instead of 60V which makes more sense for this pcb that operates at 6-24v
17A continuous instead of 8A because...more better
Only a few cents more

Low hanging fruit is added esd protection. But maybe also add varistors for protection against accidental disconnects while powered.
