Question:
We have an older unit; 2001 R-Vision. I have a question about the little colored panel lights regarding the level of charge the battery is at in our RV. Are those lights accurate in regards to the charge level on the battery on ours and even the newer RVs? If not what would you recommend as a good accurate battery tester to determine the percentage of discharge?

Answer: 
Great question!
The light gauge inside the RV is not very accurate. It is there to give you a ball park reading. If no power is being used, that is when the gauge is the least helpful. If the unit is turned on or you are using power, that is when it is the most accurate (But again the gauge gives only an estimated charge reading).

The most accurate way to know the charge/discharge of your Battery is with a product by Zamp Solar called Battery Check (Wireless Battery Management). This product can be used in use with your cell phone (No Solar panels needed). This product retails for about $269.99. It gives:
- Real time Battery Data (Volts, amps, time remaining, temperature, battery status, state of charge and battery health)
- A free downloadable app for your phone
- Easy installation (DIY)
- Settings for automatic alarms with use on your app
