We bought a BMV-712 for our Tab that's on order to monitor our dual AGM batteries. I saw this note regarding the ~$20 add-on temp sensor. Is the temp sensor worth the tradeoff or should we skip it?
- "When using the temperature sensor, the second battery voltage and midpoint voltage monitoring are not available"
Wouldn't the two batteries wired in series have close to the same voltage if identical brand, model and age?
