Is your temp gauge segmented (notches)?

So my question, even though I do need lvl 2 charging, I'm wondering if charging lvl1 sometimes when its very hot at night would be better for the battery. Once I get a lvl2 installed I can compare.

Yes. The battery power dissipation is I^2 X R (battery resistance) while charging;

Power (L1) = I ^2 X R

Power (L2) = (2I) ^2 X R = 4 X Power (L1)

but T2 = T1/2

So the heat energy (power X time) supplied to battery is 2X for L2 versus L1.

You can adjust the numbers based the actual L1 versus L2 currents and times.
