I can't afford a CA setup. I bought a Watts-Up watt meter to hookup. I have a 48 volt battery that always stays hot. I was wondering if I can use a Xt90 with anti-spark on the source side of the wattmeter to avoid getting sparks when connecting and disconnecting the power source? Would the wattmeter measure the small resister inside the Xt90 and give me a false reading? Any suggestions would be appreciated 8)
Ok, first question is what do you mean "I have a 48 volt battery that always stays hot." please be a bit more clear on that statement.
Second, yes you can use an XT90 on the source side, but it would not stop a spark on the load side.
Third, are you intending to use the meter between the battery and controller, or between the battery and the charger?
Fourth, if you put the anti-spark Xt-90 before the meter the meter will not read any power draw from the connector.
So just where do you intend to put the meter? Between the battery and controller or between the charger and battery?
