50 amp Volt/Amp Meter W/O EXT Shunt ?

I saw, but cannot refind, that one of those Ammeters on RJ's link, had a hall effect sensor for the Ammeter instead of a Shunt.

Looked big enough that 4awg wire could be fed through it.

I have a Turnigy, well GT power meter, that gets really warm passing 30+ amps. But it can count amp hours and some other features which make it much more useful to me than just a standard Ammeter.

I'd love to get some fatter wire attached to the two sandwiched circuit boards, but the negative board is inaccessible unless the boards can be separated, and accomplishing that would require better tools and skills than I possess.

I wouldn't chance it over 5 amps...I don't see any shunt on the circuit board

The Turnigy meters that many of us are using, have an internal shunt good for 60 amps
I think Hobby King the sellers spec 130 amp peak, but this is surge value for the electric motors in RC aircraft, I believe it's 60 amp continuous
I know mine is over 5 years old and still working

Seems like there could be voltage drop from a warmed up circuit board, if it ever really saw 50 amps. Maybe I don't need it.

It is measuring the current through the bigger yellow (possibly black)/red wires.

My guess is it can handle the current safely since the monitor lead length run is so short.

However, the wires that connect to those thin wires will have to be sized correctly for 50 amps for distance.

It is cheap, so buyer beware...

Normally a meter such as this would require a current shunt.

I don't know I could get it hooked up-

Thin red wire: power supply input anode (DC 4.5-30V)
Thin black wire: power supply input cathode (DC 4.5-30V)
Thick red wire: measure positive voltage input (voltage displayed between thick black wire and it is the voltage displayed on meter head.)
Thick black: measure current flow (between thick black wire and thin black wire is communal land, it is connected.) (measure negative voltage input)
Thick yellow wire: measure current inflow (connect with load cathode and the load positive pole connects with thick red wire.)

Kind of confusing, in a machine translated way.

Also- read the comments-

all 8 units came with NO shunt resistor on board - CAN NOT measure Current. i assume all comments above are fake beware!
