I am looking at building a HV EV and am looking at SoC meters that go through a shunt (see pic). Most of the ones I find are designed for a maximum of 80 V. My battery have an output of 288 V and I was wondering if a shunt lowered the Voltage so that an SoC of 80 V would work. If they don't work, do you guys know of any HV SoCs?
