Hi,
I am installing a pre charge circuit on my 72v ebike build. Battery is 20s10p of Sony VTC6. So capable of 150amps+. So I want to avoid large sparks on connecting the battery.
Can you please confirm a few things.
Does the resistor come before the switch? Battery>Resistor>Switch>Controller.
What switch is suitable. What specifications should I look for. (I have blown up 1 in the past and am now scared )
What size Awg should I use for pre-charge circuit. Heard that 14awg is suitable, but want to go as thin as possible.
Plan on using a 1000ohm 10watt resistor. Particular one in the link.
