Yes time permitting I’ll detail the nightmare in detail which will help others and that is the aim here to share productive knowledge. I had the car Transported to an active Tesla enthusiast who is active here and on other places on the internet. I’ll ask his permission prior to introducing him...

Very very long story. Short end of it: Both HV and LV battery are replaced. Car is alive, had to replace the HV battery cuz the cells had dropped too low to recharge. Another revelation was that the HV battery most likely either was swapped (by Hertz) before listing on Copart, cuz no one else...

I appreciate everyone’s productive input on this matter. As I said in a previous post, worst would be pushing this vehicle off the cliff (not there yet) best already is gaining knowledge which is priceless :) I’ll get a new battery from Tesla, just waiting for the lovely rainy weather to go away...

I have managed to locate the video someone well versed in Electronics and specially in the new battery architecture. Recharging them manually is not officially recommended or supported by design. Please see the link below. Once the new 16v batteries pass the low charge threshold, they need to be...

Thanks Yes I’m trying to align all the items so I don’t end up killing the new LV Battery. Tesla here in NJ doesn’t charge the 16v Batteries. I don’t want to rant here, but I have been to 2 different service centers. One with the car and the geniuses there tell me to dump the car without...

I’ll pick up another new Tesla 16v battery from Tesla in a day or so. I do t think I can charge the existing LV battery with an external 12v charger. I have to remove (bypass) the BMS on the battery (torch it open) and then charge it. Few ppl on YouTube show it but it’s kinda risky and I don’t...

Dettached the LV cables under the seat. Powered on and I see 11 Alerts, besides the battery, coolant and Tire pressure, anything interesting standing out?

Yes I did reach out to this gentleman who’s doing some neat things with the technology. I believe the new software requirement is to have ATLEAST 10% battery. I’ll confirm when I try it with the external PS. Thanks

Appreciate the detailed insight, will give this charger a try and see if there is success. Thanks

Yes, that is correct. The intention of buying this was to use but I learned a lot owning a non usable car lol. I can try to get a new LV battery, try to fire up toolbox and clear codes. It’s a shot in the dark, as I’m unable to find much info on toolbox or someone who actively uses it. Let’s...

I have seen crazy ppl on YouTube open the battery with a torch and charge with a 12v charger. I don’t want to burn the house down so, worst case I can get a new LV battery. But I was curious to know if external power and LV battery plugged in can somehow let me update the firmware. (Most likely...

LV battery in NJ is $220. I can get a battery from them but they won’t install. I don’t think I need Bestbuy kids to install a simple 16v battery. At this point, I prob have more experience on this car than a junior level tech at Tesla (no offense) :D

So initially when I went on this venture, someone in the Tesla community thought I needed a vcfront which was swapped but later on taken out as that was not the issue. Airbags and Pyro were good. Perhaps the car sees old alerts which need to be cleared with an external or new LV. Question for...

LV BMS will let it recharge? I think couple month ago before buying the last LV battery I did try multiple chargers even the Lithium battery ones, but they all failed to charge the LV battery. Do you have any particular recommendations on the charger?

I tried to update the software but since the LV is too low to perform any task, I may have to buy another LV. Could I run an external Powersupply and try to update the firmware or LV being too low will not let me update regardless if the external power supply is attached to the LV terminals.
