Help! - First Electric Longboard Build

Yeah should be

I’m planning on building a 12s, VESC and 6374 motor and use anti-spark xt90 rather than a switch. Does that mean I’m gouna have a problem?

All good with the antispark plug (sparking was only a problem without it). Only issue with the antispark is if you don’t insert it entirely the power will flow through the resistor in the plug and basically burn it up otherwise strongly recommended.

Personally just have a female jack between where the two batteries connect and I put my loop key in there to complete the circuit and make the final connection between the two batteries for power to flow. You can really put a female jack anywhere on the lines between the battery and the ESC though to open the circuit when the loop key isn’t inserted.
