Luckily (for you) I had to open my VESC enclosure yesterday, because I had some connection issues with one of my hall sensor plugs.
Cable tension relive:
NRF Transceiver & BT Module and 14 ultra low ESR caps:
6mm bullet connectors for the VESCs:
Microswitches to add the possibility to disconnect every single VESC in case of a fault from the CAN bus:
20µF on GVDD, 0,0005 Ohm shunts for up to 240A current measuring ability, NRF extension and BT directly soldered to the PCB:
VESC with heatspreader soldered to the common positive FET connections, 54V TVS diode on top of of the big ceramic cap. Hard to see under the heatspreader:
With these mods the 4.7 VESC run fine at 120A motor current:
