Capacitor instead of spark loop key?
#2

Where are you shipping from?


#3

from Russia


#4

What FETS are you using?


#5

all components are from Vedders BOM (IRFS7530TRL7PP)


#6

gotcha. just FYI these are solid at 10S but at 12S they will give you issues unless you upgrade the FETs.


#7

thanks for info. for 12s users I can change IRFS7530 to IRFS7730 for free :slight_smile:


#8

are you building these by hand? If so, that’s a nice upgrade to do on request, but the price difference on bulk orders may not be worth it to keep doing the 60v ones once you run out.


#9

yes, I build this by hand (air flow soldering station + heated bed)


#10

Are you still making these to sell?


#11

yes.

#12

Hey guys if you rate the mosfet for 14s will the switch run on 12s better or cooler? Or will it limit current


#13

better - maybe.
cooler - no. switch with IRFS7530 will be cooler that IRFS7730 at the same current.


#14

What do you mean, so what I’m saying is I have 12s and want to upgrade to 14s in the future can I make one switch for both


#15

Does anyone know if the fuse blows if you pull 50A or 60A for short periods (5-10 secs)?


#16

yes, you can.


#17


#18

Thanks @eLDoska that is really helpful. So you could pull 54A continuously for 30 minutes, that’s a very long time. I think I’ll increase min per vesc to 25A… that should give me 50A in total and that only for a few seconds when accelerating hard.


#19

What do you mean by this?


#20

can i change the switch?
