I always enjoy your videos. I have now had my SR + MIC (LFP) for 15 months and you have already mentioned the advantage of being able to utilize the full capacity of the battery on a daily basis. In addition, an expected very long service life. On the downside is a lower charging power and a bit more sensitivity to cold weather.
@@tooltalk Loss of range is not a sufficiently accurate measurement method. I can't tell you about the loss after 1 year, but after almost 3 years and 29,000 miles, the battery in my M3 SR+ MIC (55 kWh LFP) has lost about 6.6% in capacity.
A lot of people don't understand that you should charge a LFP to 100% because they've always heard that you should never charge a Tesla to 100%. Of course LFP is different but that adds an element of confusion to new EV owners.
They charge to different top levels discharge at different rates, and have different bottom voltage. Life of lfp is much better, li-ion is more power dense. They are different. And require different procedures. Almost like diesel and gas motors are different.

I have had my M3 60kwh RWD for about 5 months, for the first 3 to 4 months during freezing conditions I would always get a mileage reading at 100% / 274 miles. After 5 months I now only see a maximum of 270 miles when charged to 100% and charge to 100%, twice per week. The temperatures now are a lot warmer (UK) plus the car has covered 6000 miles. I actually thought it would show higher millage during higher temperatures.
@@martingrady7654 Driving habits (ie: what efficiency you get) are generally recorded by the car and effect your stated range. The range shown on the dash in an EV is never a useful indicator of battery degradation, only way to know for sure is to run the car flat, fully charge it and use some means to record how many kwh went into the battery pack during the charging session.
Very informative. Thank you. I just received my Model 3 RWD with LFP. Just to confirm and as a general rule, should I always plug in at the end of the day and let the battery charge to 100% regardless of what percentage the battery is at that point? I usually use around 20% of charge for my daily commute. Or, should I let the battery get down to a lower level (like 50%) before charging to 100%? Thanks!! 😊
Very informative. Thanks! I have LFP on my M3SR '23 and didn't really read over the battery information with close scrutiny. I'm wondering if I'm out on a trip that lasts longer than a week should I just keep it plugged in to the wall charger so its always at 100%?
If its for a trip away from home, yes, keep the battery topped off at every opportunity. You never know when you get to a public charger if there will be an open slot, or if the only available charger is working or not.
Hi love your thorough approach on every topic you tackle!! Thanks Regarding LFP, one thing that remain unclear for me is. When we don’t use the car let’s say for 2 or 3 days what’s the ideal pourcentage? Should we consider that leave it at 100% for several days is OK or not OK ?
I have this exact same question and I can’t find an answer anywhere :( . We don’t drive much and I feel that leaving the car at 100% for two or more days is never a good thing. The manual may assume the car is used every day.
2021 M3 Sr+ with 220kw motor + LFP Battery, just hit 153,000 Kilometers, my battery health is at 90% which is expected nominal reduction, Charging would be around 90% done on a 32 Amp Single Phase AC outlet and most range loss would have occured in the first year, The drive unit is being replaced early this coming January 2024 for free (By Tesla of course), as it started making an odd sound, localised within the drive unit. I have done some crazy driving, and utilised the vehicle as an uber for 95% or greater of all the stated kilometers. They say drive train issues are rare, but also, I would say there is a select few vehicles out there from 2021 with this amount of kilometerage on them...That have also had to work this hard.
thanks for the vid! due to a surgery i wont b able to drive for two months, so ill have a buddy charge my lfp m3 to 100% every 2nd week for 6 weeks, is this ok u reckon? I know ideally u would want every week or more often to 100% but it is what it is
Thats stupid, what if you want to use a supercharger, and limit the amount it will charge to reduce the amount of supercharging, you accumulate, but you also need to step away for a bit from the vehicle ?
Hey FTG, Hope all is well. Hey- How do you find out what type of useable battery capacity? I have Model 3 2020 LR. Not sure if it has 77k/Wh or 82kW/h. Or neither of those…. Thanks for your help.
Little off topic, but have a quick question for. I’ll be out of town for 2 weeks and wondering what I should do while I’m gone, keep it plugged in and set at 90% charge rate? Or do u suggest something else?
Historically, the Tesla manual said keep car plugged in while away for several weeks/months. Phantom drain will deplete battery, especially if Sentry is on. If in a very warm climate, cabin heat protection will periodically come on too. My previously owned 2017 mS was left for 10 weeks at 75% and plugged in. Of course, this is good for NCA batteries, but LFP is better at 90%.
Set it to 100% as LFP batteries should be charged to 100% at least once a week. Otherwise it’ll mess with the battery calibration and the car will think the battery is smaller than it is
OK so I have a Tesla 3 2021 model in UK. I was told it was from Shanghai plant. After 3 months the battery would not charge so Tesla replaced the battery. I thought I had LFP battery as after the new battery was installed the read out show 50%-100%. However things changed after 6 months of so the display reverted to show daily - trip.....any one had this? I am going to check it with Tesla....strange...
@@shareg2421 Tesla have now confirmed the battery that was replaced was not LFP despite being told so at time of replacement, no explanation given for the change in-read out and advised to follow usual instructions for charging. Confused? I was but will just follow what I have been told.

We just had a LFP battery “meltdown” going through Arizona 116 degree heat. 40-50% of charge disappeared relative to projected use. We were driving below speed limit. Anyone know how this happens?
Ok I’m confused, I just took delivery of my 2022 model Y performance and it say in the manual to go to control software additional information. But it only says I have a low voltage battery nothing about the high voltage battery. I also was told the 7th digit in the VIN will say what type of battery which when I checked I have a “E” which means LFP , but on my charging limit screen it doesn’t have the 50-100% scale it has the “trip” scale . How do I know for sure so I can charge the car the correct way? I would really appreciate help with this. Thank you !
you don't have LFP, just charge to 50-80% for daily use and 95% for trips. if you charge to 100%, you will lose regenerative breaking, and also charging from 95 to 100 takes a lot longer and isn't healthy
Odd coincidence. I also had my car 4 months with 2,000 miles on it. I get 267 max charge now. New, it was 272 miles. Already lost 2% range. My car is driven in California, so the temps are very ideal for electrics.
Same, I'm maxed at 267 now and I live in Los Angeles. The only time I was able to go back up to 271 was when I drove the car to 4%, let it sleep for a couple of hours and did a slow charge for a couple of days and was able to reach 271. @@jimbochoo3316

while there is a small/technical benefit going down to 20%, the benefit is not practical. Going down only shows the car the current full capacity of the battery but there is little degradation in an LFP, so need.
I got the lfp battery myself and it would seems so. The LFP battery are Chinese made and uses cheaper materials. They're marketed as degrading slower than Li ion battery but that's unproven and they seem to be unable to accurately record charges very well. Some online sources even mentioned that lfp owners are also suffering from more range lost compared to li ion but that still needs to be confirmed.
I would prefer to get LFP battery, from my experience with solar storage. LFP batteries can get 5-6000 cycles before they degrade to 80%, that is 4-5 times more cycles than standard lithium ion, and probability for fire is much much lower for LFPs (I would never use lithium ion for solar storage). On the other side, they are heavier for the same capacity, and can give a bit less power.

an LFP battery is still a Li-Ion battery, Li-ion, describes the technology that both Li-NMC and Li-FePo batteries utilise to propel electrons.
LFP are still lithium ion batteries. They simply have an iron based chemistry rather than a nickel chemistry. It shouldn't read LFP or lithium ion.
