Conflicting info on battery heater

[Zooomer]

The forums from what I have read say the battery heater is 6KW IIRC but on Ebay looking at used heaters, they say right on them 1000w. If this is correct it would take nearly an hour to raise 1400 pounds a deg C which isn't the case. What am I missing?

I did a quick search on ebay and those model s battery heaters that had wattage on a label said 5556 watts, so i'm not sure what you looked at..

120v 50-60hz. Interesting.

And weird, as all other tesla model s battery heaters are 450VDC.

I'm pretty sure that isn't a battery heater that is used in a Tesla. But it is something you could use to heat a Tesla battery that you were using for stationary storage.

Are there two? one that runs off the battery and one for shore power when plugged in.

I thought The tesla system was 384volts and charged at 400v DC?

The voltage varies based on which battery pack you have. Tesla essentially has 350v and 400v packs. (Fully charged voltage.)

The Tesla heater looks more like this: OEM #1038901-00-F Battery Heater TESLA Model S 85D AWD 310 kW421PS04.2015-02.20 | eBay

That Ebay ad, says it's 310KW. I doubt it.
Looking like 5KW for a 16 module vehicle and 4.3KW for 14 module vehicle.
The heater says 12.3A which would mean 4920 watts in an 85KW and up and 4300 watts in a 60-75 vehicle.
