Hi,
I'm pretty sure my next set of 8 bats will be 12 volt AGM--unless LI drops to extremely reasonable prices.
FWIW. It is Jan 6, 11:30AM, and I just observed my highest temp comp'ed charge/ABS Volts of 15.45 via the MS TS 45PWM into the AGMs. The overnight low was 3F and the TT is stored in the driveway. This is the beauty of automatic and unattended temp comp charging. Always a good thing with AGMs.
HTH;

Are you sure you are not boiling off electrolyte with that high a voltage charging at such a low temperature in your AGM's, for there is no replacing water on them? I defer to Mexico Wanderer for the facts on this.
