How longa are the wires and cables?

The sensor come with 2 meters long cable, factory can customize longer cable.

I just received this and there is no install instructions for automotive car install. Do the black and red leads connect to 12 volts source voltage?

I think there are 2 ways to wire. 1, from a power source 2, from the induced power from hall tranformer. Look at Web sitell it shows schmatic.

Does this version Have ability to reset ah and kwh?

This battery tester/gauge is just a display device. If you remove the monitored voltage/current the meter automatically resets it self. Actually it just turns off and when you reapply the voltage/current it will show the new data for the system you are monitoring. Hope this helps!

will I need two being I’m using a battery isolator for my two batteries for my audio system?

If you are isolating each battery from the other then the I think that the answer is yes. You would need 2 to be able to read each battery independently.
