Amp meter, like voltage meter

Redirtroad

is there anyway to have a digital amp meter, like a voltage meter.

the you can see how much current you are drawing off batteries and how hard you are running your motor

Yes, you have to install a ammeter shunt somewhere in the high current loop and feed the output to a dash mounted meter.
Something like this: http://www.ebay.com/itm/DC-500A-Digi...-/180560417586

Another handy gadget is a temperature sensor for your motor.

I had a cart with an ammeter shunt installed. It was only accurate at full throttle. Part throttle gave very erratic readings due to the PWM output of the controller.

never thought about it like that. ok well thanks for the input

Mine works fine.

Interesting. I see the shunt and meter in your picture. What is the item in the bottom left of the 1st picture? A filter?

I have ordered a dual volt/amp display that is on a slow boat from ROC. I plan to post my results after I receive it and get it programmed. The meter has several other functions:
http://www.ebay.com/itm/171298215601...601%26_rdc%3D1
Voltage (V), Power (W)
Current (A), Ampere-hour (Ah),
Working Hours (H),
Alarm control when over/under limit (Built-in Buzzer)
Flexible On-line calibration function, calibrate Voltage and amps reading easily.
By turning External device Relay on and off, it can control external devices, such cut off Power Input
[OVP] Over Voltage protection
[LOP] Low Voltage protection
[OCP] Over Current protection
[OAH] Over Charge protection
[OPP] Over Power protection
[OFT] Over Time protection
Adopting modular design, collocate indicator lights on the panel for various working status
4 digits LED, High accuracy
Expandable with ext'l Shunt and Relay

Sorry Reddirtroad, I'm out of your league, but I'm learning. I see the pro's answered.

An isolated DC to DC PSU. I forget the voltage, but I think the ammeter wants an 5 or 12 volt isolated PSU. The PSU wants a certain amperage to be accurate, so I added a burden resistor to make it happy.
