Wiring diagram input | 18650 | BMS | Loop key

Hey, I am building my first electric longboard and have got all the parts. I am planing to build an 18650 pack with bms using Samsung 25r cells in sleds. I have inserted my wiring diagram below and just wanted to check if I have drawn the wiring of the bms, Loop key, charging port and voltage monitor correctly. I just want to be sure before putting it all together and would be very grateful for anyone’s input.

Thanks!:slight_smile:

Don’t you want the voltage meter after the loop key? Else the meter would be permanently on.

Thanks @rwxr, Is this what you mean

and is there anything else I missed?

LAWG of wire and are you using XT90s everywhere? Your diagram looks good now that you moved the monitor. If you do not plan on pulling more than 60A then I would use XT60s everywhere except at the loop key since they only make XT90s anti spark.

You missed one balance wire coming of your ground.

I am using 12 AWG wire and XT60 connectors everywhere beside the loop key where I have an XT 90S anti spark connector.
