The 60% Rule Your BMS Has Been Logging (Most EV Owners Miss This)

The "80% rule" is the most repeated EV charging advice on the internet — but it's missing a critical variable: your battery chemistry. NMC and LFP cells operate on completely different voltage curves. For NMC packs (Ioniq 5, EV6, Nissan Leaf, Tesla Long Range), charging to 80% daily still keeps your cells in an elevated stress zone. Battery engineers recommend 60% as the true daily limit for NMC longevity — and your BMS has been logging capacity fade data every time you've exceeded it. In this video, I break down the chemistry difference, what your BMS event log is actually recording, and the exact charge limits you should be using based on your specific battery type.
