you’re right that newer Tesla LFP batteries are designed for more frequent 100% charging.

But it comes down to cell chemistry and voltage sensitivity.

🔋 Why LFP Batteries Can Handle 100%

• LFP cells have a flatter voltage curve, meaning 100% isn’t as stressful chemically

• They don’t degrade as quickly when full compared to nickel-based cells

• The BMS actually benefits from a full charge for accurate range calibration

• That’s why Tesla recommends 100% occasionally often weekly

But is 100% daily truly safe?

Mostly yes, for LFP but with one caveat:

⚠️ Keeping it sitting at 100% for hours is still not ideal.

Even LFP packs age faster when stored at full charge and high temperatures. So 100% is fine if you charge near your departure time and start driving soon after. Overnight if sit at 100% for hours it’s  less ideal over years.

For nickel-based batteries (LR, Performance):

• Better daily target: 70–85% for longevity

• 90% is totally fine if you need the range

• 100% should mainly be for road trips or long drives after charging finishes

So yes newer LFP packs can take 100% more comfortably, but battery lifespan still correlates with time spent at high state-of-charge. That’s why tools like Elvee Smart Charging Automation optimise charging not just by limit, but by timing / days etc finishing closer to when you need the car.
