  1. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    Agree to wanting data. And since we don't have the data, we can't make wild predictions. But based on Tesla's fleet, we should get 250K+ miles which is more than enough. How many people keep their vehicles that long? Very, very few.
  2. Diesel heater(new video of it running)

    I KNOW. You are so right. Why does FORD not offer an extreme cold package that adds the fuel heater? They are just so damn slow at everything.
  3. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    You just need to be contrarian don't you LOL, that's fine... There is no data anywhere to support any hypothesis that current EV lithium ion batteries can last 10K charge cycles. The BMS will fail the pack way before it lets you keep doing dangerous recharging on damaged packs. In 28 years...
  4. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    NO, this is a direct copy/paste of what I responded to: >>> According to Ford the F150 battery pack has a lifetime charge cycles of 10000... So basically 28 years if you charged to 100% every day.... Now battery degradation, that's another thing....guessing around 1200 to 1500 for 80% <<< Do...
  5. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    I didn't say it would explode after 1,500 charges, but it will be degraded. Even 1000 charge cycles is already 250K to 300K-ish miles which is plenty.
  6. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    True, but that's a deceptive number. 1000-1500 full cycles to maintain 70-80% of capacity. I didn't say they will explode after that. But nobody knows what will happen to Lightning batteries in the very long term. The 1.2 million mile Tesla owned by Hansjorg von Gemmingen-Hornberg is on it's...
  7. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    It's definitely not 10,000 charge cycles. No lithium batteries come anywhere close to 10k cycles. Closer to 1000 to 1500 cycles is common for current generation lithium batteries.
  8. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    Who knows. Can't say anything based on this data. But 80amps is WAY below the 400-500amps that DC fast charging runs at. It's hard to imagine 80amps causing an issue.
  9. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    Without full context, it would be hard to draw any realistic conclusions. The calendar life tests don't make much sense. 45c/30%SOC didn't complete, 45c/50%SOC one cell apparently died after 8 weeks, 45c/80% seemed ok. In the charge cycle tests, both cells died at 10/12 charge cycles at...
  10. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    Why don't you just summarize key results like any research paper would do instead of making us decode the graphs? For example, in the charge graphs, some of the cells drop off a cliff at a low number of charge cycles. But is each test a single charge cycle or does it cover a group of charge...
  11. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    Yeah I'm hoping in 10 years that a double-capacity battery at roughly the same weight will cost less than $20K. Given current trends, should be very possible. The only question is the difficulty of integrating with the truck. Might just be more cost effective to buy the updated trucks.
  12. Bluecruise - stop and go traffic

    BC works great in stop and go. I probably still won't pay for it once the trial ends. The radar-assisted cruise does most of the heavy lifting in traffic anyway and it's free forever. I'm not paying $??/mo to have the truck occasionally steer itself.
  13. It's All About the Delta (and Temperature, but the BMS will Protect You) -- Test: Effect of temperature on battery cells life

    This doesn't say much really and the information is presented in an intentionally cryptic way. A bunch of graphs with no markings isn't very informative. They did up to 20 cycles of something to the pouch cells. Apparently, without temperature management that the truck would do via liquid...
  14. I love this truck but GD!

    If you want to keep it, maybe look at adding a fuel based heater to the coolant loop to warm the batteries. Other people here have done it and it works to restore range. You live in a pretty harsh climate, doing a winterization customization might make sense. -10F is going to eat 30% of range...
  15. I love this truck but GD!

    Are you preconditioning the battery while on L2 power? Because the battery is really not going to like being cold soaked to -10 all the time when it comes to range.
  16. Would You Buy A Lightning Again?

    Given when I bought it, yes I would go back in time and still buy it. But more options are available now and Silverado/Sierra are real options depending on price and availability. I'm definitely down for the EV trucks with gen2/gen3 batteries from whoever delivers 500 mile range at an ok...
  17. Liking my Lightning... but no way to lock tailgate in down position?

    Can you name a single other truck where the tailgates locks into the open position?
  18. Tesla NACS Adapter Recall / Replacement Notice (10/24/24)

    12021, got it mid-september, no recall email. But does look like they revisioned the part at some point since newer adapter part #s end with -20-D
  19. 1.4 kwh/mi on interstate…disappointed.

    I set cruise to 70 and get 2.3-2.4 on most trips. This is in California though, so there is inevitable traffic and my average speed would be below 70.
  20. 20,000-Mile Service

    That isn't coolant. It's transmission fluid for the gear reduction set which I mentioned as "other maintenance items." I guess because the gear reduction set is integrated into the BW motor, you can technically say it's in the motor. :)
