**Q: Does this version Have ability to reset  ah and kwh?**
A: 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!

**Q: will I need two being I’m using a battery isolator for my two batteries for my audio system?**
A: 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.
