I had a mobile tech worker told me that all Gen2 large packs are software locked MAX packs.

But who knows, but I do think this makes the most sense.

Thank you. It is great to see Rivian making good vehicles and adopting new technology quickly for being such a young company. I still don’t like Rivian and Tesla releasing semi beta products for sale, though Rivan vehicles seem less beta than a typical new Tesla product. I can somewhat forgive the LFP battery situation because crowd sourced data is instrumental to fine tune the charging curve.
This is so cool that @brandenflasch was able to provide such high resolution data on the charging curve! I hope that you will be able to get this level of detail in the future.
It's nice, in the sea of "hot takes" and random junk that RUclips throws at you, to get some actual data and meaningful information. LFP Rivian is where it's at.
I have to agree with Tom. I own an older Philips with the same saeco internals. Not a bad machine but it only grinds around 10 grams each time, which tends to create a lighter coffee. Plus, the saeco internals are fussy and will require regular maintenance with disassembly, cleaning and silicon grease. Other that, if you do that they will last with a few silicone o ring replacements from time to time.
I can’t wait to see the towing performance. Not the extreme max load, the normal/everyday type loads. My bay boat on trailer come to right under 3000lbs fully loaded.
Winter performance, especially if charging after leaving a hotel, will be worse with LFP. Slower when cold, even if it doesn't have to furiously cool itself between charging stops when hot.
I agree this is the one to get..., the dual motor with the base LFP battery.. similar to the Tesla model 3 LFP ..I road tripped this past June over 4,500 miles..
The other reason to go to full charge is for cell balancing. Because the battery is flat it's hard to tell if a cell is out of balance unless you go to a high state of charge.
Hey, Kyle. Love your content. I’ve learned so much watching your videos. I’m definitely an EV nerd. I own a 2023 Tesla Model 3 with an LFP battery. I know you have talked about how you keep your EVs charged between 30-50%. I wish I could do that with my car, but I’m constantly bugged by Tesla to charge it to 100% once a week. I hate doing it (I’d rather charge to 80% and run it down to 20%), but I feel like I have to to keep my BMS happy. If you owned an EV with an LFP battery, how would you charge it? I daily drive it and charge it once a week to 100% (it finishes charging minutes before I jump in it to drive to work). Just an aside, I know estimated full-charge mileage is not a great indicator of degradation, but I’ve gone from 272 to 260 miles in 17,000 miles.
LFP seems super resilient - I have a 2022 Model 3 LFP with just shy of 100k miles - 25% AC charged and 75% DC charged, always to 100% SoC. Full charge range shows 256 miles, and when doing a proper capacity test, I measured about 4.3% degradation. I personally used to be a total nerd when it came to charging - when I had NMC EVs I’d always keep them between 30-50% SoC and would baby them as much as possible, but with this Model 3, I just do whatever I want and the car holds up.
I have a PDM Max pack which has been great, performance-wise. 92 kWh usable in the LFP...so maybe 101 miles pulling my camper...that's a NOOOOO Thank you. But for many, this will be a great option.
I really want to see standard r1t but r1s lfp full range test. Really looking at lease an r1t later in the year and coming from a 2022 p2 long range lease, and so far looks like lfp will have better range, faster charging, tesla network, and about the same performance with better utility
9:25 LFP or NCA in EVs usually will have some bottom buffer by the BMS. Most, if not all, OEMs do this to avoid deep discharge. Whereas they differ in the top SoC near 100%. Also, if you want good charging performance to 80%, charge from 10%, not from close to 0/1%, as that 1 to 10% adds to the thermal buildup early on, dropping the charge curve prematurely. Remember, these cells are tall with bottom cooling and high current loading when their SoC is low, so a high thermal gradient buildup occurs. So, don't expect the delta 70% (10 to 80%) time to meet the OEM-quoted time when you start from 1%.
Charging from low state is just to show how longest case the charge is gonna be. If you start charging from a higher SOC the charge time of course is gonna be shorter 😅
Really wish Kyle would get an interview with the Rivian battery team and really ask why their charging speeds are so slow compared to others, what has to change and why it hasn't changed and why such a large battery has such a slow charging rate when we know its possible to charge large batteries faster?
Been looking into the Rivian R1S and it seems that there are several 2023 R1S's on the market with milage from 5,000 to about 25,000. Any idea why? Are these people upgrading to the new tech/battery? Are people finding out they don't like the R1S? What does someone want to look out for in buying a used R1S?
This is not a problem as long as the car has a battery heater and you precondition the battery before fast charging.. LiFePo4 batteries can charge with negative battery temperature, but at very low C-rate.
Hell yes! Was hoping you would find a way to do this! Can we expect a range test as well? I want to know all the nerdy details so I can decide if I really need the large pack or if standard is best for my use case.
Large Pack is a software locked Max Pack. Thats why Rivian claims it takes a shorter time to charge the Large Pack compared to 41min for the Max to go from 10-80
@@mp3mike237 Thanks. My Lightning is about 40 min for that same range - not bad. I've taken it on a few road trips and it does slow down your pace a little (but its comfort makes up for it).

@@4literv6 would be interesting to see whether they changed cooling strategy or not, those cells are really tall and if they still use bottom plate cooling I'd be worried about overheating on road trips
My ID.4 battery is on the contrary always heating in the winter. Does it mean that this battery would require more heating in the winter compared to regular?
13:55 No, you shouldn't. Leaving it at 100% has nothing to do with cyclic degradation, it's about calendar degradation and LFP ages much like the high nickel chemistries at those high SOCs.
If I'm reading the graph correctly, even though the charge starts at around 200kW, it looks like it drops to only 50kW by the time you hit 80%. Don't E-GMP models retain double that rate at 80%?
Why wait for just one update? Using your logic, it makes more sense to just wait until Rivian pushes out the last update on the battery pack. Sure, it might be a few years, but then you only have one video to watch. Genius 🤭.
Will the BMS on a LFP battery get confused on a road trip with 6-10 charge stops if you keep the battery between 10%-80%? Fully calibrated when you start. If the BMS gets confused, then will that cause issues charging?
I’ve been on five 800-1600 mile road trips in my Model 3 LFP. Haven’t noticed it becoming confused. I have pulled in to charge with 3-6% five times and haven’t run out of battery, but I usually shoot for 10%, and often end up arriving with closer to 15%.
Huh. 1.25 hours empty to full is just 1.25C. The internal resistance for LFP cells tends to be lower than for NMC cells, (roughly 0.10 to 0.20 mOhm vs 0.50 to 0.80 mOhm) so I wouldn't expect the battery pack to actually heat up that much during charging. They are clearly being ultra conservative on the charging curve. A LFP battery should be able to take 1C or higher charging up past 90%. It could end up being just a cabling limitation. -Matt
@@tooltalk I wouldn't touch NCA if my life depended on it. In terms of volatility and fire hazard, LiFePO4 (LFP) is the safest, then NMC, and the absolute highest energy density but also the most dangerous is NCA. I personally prefer LFP despite the lower energy density because the cells basically don't wear out, don't catch on fire, and are extremely robust in general.
@@junkerzn7312 All lithium ion batteries, including LFP, are combustible. LFP has higher TR (thermal runaway) threshold, but all it means is that it requires a bit more work (or energy) to catch fire. And when it does catch fire, it spreads faster and it is potentially more dangerous due to hydrogen gas produced. Further, LFP's degradation mechanism depends on application -- LFP's durability is optimal under ESS (stationary energy storage system), but not so in EV (moving vehicles). That's also why LFP is almost exclusively deployed in entry-level, low-range EVs.
@@tooltalk LFP's thermal run away not only has a higher threshold, it also has 1/100th the thermal gradient of NMC during a runaway. And unlike NMC and NCA, the voltage more or less instantly relaxes after charging is complete. The differences are literally night and day. LFPs degradation mechanism has little to do with stationary-vs-EV. Not sure why you think it would. The average C-rate is comparable and as I mentioned at the top, LFP batteries don't generally have much of a problem with temperature or C-rate stresses. The reason EVs (up until recently) used NMC is simply due to the higher energy density. Not the degradation or anything else. But LFP chemistries are fast catching up in energy density and customers are starting to prefer them for safety and longevity over NMC, despite the lower range. -Matt
After getting my NCA pack replaced with an LFP pack under warranty by Tesla at 20k miles. Yes 20k miles. Im swearing will never buy anything but LFP. 😂
With CPO’s now looking at excess stay charges for charging above 85% this calibration to 100% is going to become expensive on a DCFC if you also recommend that the car isn’t left standing for any time at very high and very low SOC and might happen on a home charger utilizing off peak electricity rates. Maybe LFP isn’t the answer after all.
how can you recommend this without knowing the -20c to -30c usage experience? we had cars not manage to charge "at all" last winter as they had a bad battery heater system.
Elefpee? LiFePO4 pronounced “le fepo fore,” right? (Sounds French, ewww) Omitting the O from the name seems criminal given our dependence on the atom for….life. And yes Fe and P are essential elements, tho we can last longer than 5 to 6 minutes without them. Thx Chris.

With CPO’s now looking at excess stay charges for charging above 85% this calibration to 100% is going to become expensive on a DCFC if you also recommend that the car isn’t left standing for any time at very high and very low SOC and might happen on a home charger utilizing off peak electricity rates. Maybe LFP isn’t the answer after all.
I see that the Hummer pickup outsold the Rivian pickup in the second quarter! Not good for Rivian!
Kyle I dbl dawg dare u to wear sumthin other than a long sleeve hoodie!
how can you recommend this without knowing the -20c to -30c usage experience? we had cars not manage to charge "at all" last winter as they had a bad battery heater system.
Lithium Ferro Phosphate.
Elefpee? LiFePO4 pronounced “le fepo fore,” right? (Sounds French, ewww) Omitting the O from the name seems criminal given our dependence on the atom for….life. And yes Fe and P are essential elements, tho we can last longer than 5 to 6 minutes without them.
Thx Chris.
Very interesting. Thanks 👍🏼
75 minutes for 100kWh ? very disappointing again to me.
You're smashing it, keep it coming!
Thats just a super basic cc-cv profile.
Lfp is heavy , only good for home storage..unless they have matched lithium wh. Per kg.
16kw home storage rack is 136kg
Great from china bad decision for ev makers.
Prefer that you don't tell me what you think you're going to do rather wait and show me what it's going to do. You don't have a crystal ball.
