No. The heaters did not come on. Set to on 40, off 45. I did test the system with an ice cube before attaching the sensor to the battery. Collectively just under 6 amps was moving evenly through the heaters giving about 60 watts of heat. No power source at that point so no temperature rise verification or performance was measured.

I assume it is good to 20f, maybe lower, and covers about the worst I would see. Could be they never activate. Glad to know they are there to buy some time so as not to create an immediate panic to roll out.

Not really an expedition vehicle. Not likely to be in Canada in winter.

Time2roll glad everything is working out. Give it a little more time and you'll really stop paying attention to the batteries because they just there in the background working effortlessly with solar at all the tasks within reason. Me personally lfp is the only way now. Until you actually get them and use them, some of the lfp stories sound to good to be true. I know with mine now after 5.5 years and the paces they've been put through it's just amazing at times....no more dead lead. [emoticon]

dont lump all of canada into thoes cold winters haha. my normal day time high in the winter is 32 degrees but I onlu have to drive a short distance to drop that significantly. on the island if you around victoria the normal day time high is 42 in the winter, but if we go to winnipeg then it could be -40
