What is the button? Not in handbook or guides.

Hello.  I have this button, I believe it heats the lithium batteries in the winter, my concern is how do I know if it's on? Is it safe to assume the red indicator means the heater is on?

That is indeed the switch to turn on the battery heater. The little red LED above the switch should glow when turned on... try it and see!

As RTWCTS stated, it actually enables heating if the battery offers the feature. It doesn't start or stop or manage the heating. It enables the feature.

I added a section to my schematic shows how it is wired when you have two LiFePO4 batteries in parallel. Before I added the second battery, the same setup was used except minus the "H" to "H" connection.

First time I ever saw a two pole lighted switch.

Could you clarify and perhaps provide battery brand literature reference . . .

As you are saying "turning the Switch On allows the Battery Internal Logic to decide if the heaters are needed for safe below freezing charging", that the battery is monitoring its temperature.  Yes?

I'm not questioning the accuracy of your statement, 
just interested in details and if this is battery brand specific.
