@Inwo @LithiumGods Hi guys, quick question: want to add a pack voltage meter. I just checked voltage across the two power connections to the controller and it read over 80v which is about right with current SOC. Is that a good place to tap or should I be doing so elsewhere? Appreciate your help and wish everyone a safe sane and virus free 4th of July! ---

at the pack or the contactor . really doesn’t matter ---

I’m adding a dash gage for volts and amps right of the glove box. I connected it to the contactor out. ---

That’s clean. Mind if I ask for a link to the gauge? ---

I have a larger unit but it only had a 12" ribbon and I was worried it may not reach from the shunt to the gauge while replacing the dash top. I had not mounted the shunt yet on the one above before a guy wanted to buy the Gem E4 ASAP, so I sold it. I was going to mount the shunt to the Contractor out. So I ended up with 3 of these jewels > **[DC 200V 500A + Shunt Voltage Current Meter Digital LED Voltmeter Ammeter 12V...](https://www.ebay.com/itm/DC-200V-500A-Shunt-Voltage-Current-Meter-Digital-LED-Voltmeter-Ammeter-12V-24V/321737795792?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649)** > > Current: 500A. 1 X 500A/75mV Shunt. --Display: 0.28" LED digital tube. --Size: 48x29x21 mm. --Panel cutout 45.5x26.5 mm.

Here’s the larger unit with the 12" 6 conductor ribbon. It will fit the same location with no extra clearance. > **[DC120V 100A 200A 300A 500A LCD Combo Meter Voltage Current Monitoring Monitor ...](https://www.ebay.com/itm/DC120V-100A-200A-300A-500A-LCD-Combo-Meter-Voltage-Current-Monitoring-Monitor/302821226963?hash=item46818d39d3:g:MvsAAOSwl39bWtSs)** > > Electric Current: 0.1A~100A/ 0.1A~200A/ 0.1A~300A/ 0.1A~500A. 4 accumulated capacity or energy value.

Thanks. Just ordered one.
