    replacement 12V batteries for 2018 M3: OEM or 3rd party "group 51r" ok?

    I already saw this thread which tells me not to buy the Ohmu lithium battery https://teslamotorsclub.com/tmc/threads/update-on-replacing-oem-12v-lead-acid-battery-with-lithium.313930/page-2 and Q1: My battery is almost 5 years old, so I understand it went past its expected life. Not sure if...

    how can we encourage tesla to give better audible alert of AP status: full, distance keeping, or off

    If someone can help me push this to Elon/tesla or whatever best channels outside of reporting it to tesla tech support who told me they agreed and had gotten people asking for the same, that would be appreciated: I'm a pilot, I know about automation in planes and/or the issue of two pilots...

    How many amps can you get from the 12V system for emergency situations?

    Question: Is there a better 12V bus I should tap into that gets more amps from the DC-DC converter than what is being sent to the battery (only a few amps it seems) Details: I'm interested in getting a decent amount of amps from my car while it's parked at home if I'm in a power emergency...

    CA South Bay Area to Kirkwood ski resort in one shot with Model 3 AWD LR

    Some of you may remember that I tried this in my model S 90D some years back, and it wasn't possible without a supercharger stop in Manteca.

    So, when is APv2 going to be noticeably better than APv1? Or is it already?

    I'm well aware that the hardware on APv2 is substantially better, but I've failed to find any information of whether APv2 currently has an AP that behaves functionally better than APv1. I have v1 and I've been waiting for v2 to be sufficiently better for me to consider upgrading (i.e. changing...

    How many Kwh usable for driving are you getting on an 85 or 90 car? (I only get 75Kwh on my 90D)

    I know you don't get the full battery capacity for driving, some is kept for emergency reserve and some just not to run the batteries flat, which would damage them. I also know that Tesla apparent does not want to disclose what the usable Kwh for driving is, for our cars (if I'm wrong, please...

    Installing a front nose dashcam through the firewall

    Existing instructions were for cars that didn't have a drain plug from the pano roof, so it took me longer than it should, but I documented the process here: Marc's Blog: cars - Installing a nose cam in a Tesla Model S, and routing the cable through the firewall

    Calculating and keeping track of my actual number of kWh usable for driving?

    Tesla does not tell you how many kWh your pack has that are usable for driving. But it gives you a battery percentage meter and the number of kWh you allegedly used. Question #1: Is the kWh used value you can display on the center console, the actual amount that came out of the battery, or the...

    Driving a 85/90D from bay area to kirkwood (1h from tahoe) in a snowstorm, and back

    I've seen some posts about driving to lake Tahoe, but that's easy :) The real hard one is Kirkwood, in the middle of nowhere on SR88 without any source of power if you're running short of course, and no cell phone reception for 45mn in either direction to call for help if you run your batteries...
