Some of the Befuddlement comes from WIVES TALES, some from FUD (Fear, Uncertainty, Doubt) and of course Confusion between Chemistries & Classes & Grades. The last one being the absolute worst problem.
EV Grade Cells are NOT ESS Grade Cells, and not Utility Grade cells or "Device Grade" (electronics like phones). and there are variations between all of those classes as well.
ESS LFP Cells for example typically have a Max Discharge Rate of 1C and Max Charge Rate of 0.5C. Where EV Grade LFP LFP can deliver 5C Max Discharge & 2-4C Charge (pending on chemistry variant). BOTH grades are "Burst Discharge Rate" capable X5 their Max CRate.) Cross into LTO, Li-Ion NMC etc and a whole new game starts.
Up until 5 Years Ago, Joe & Jane Public only knew AA, AAA, C, D, NiCad & NimHi and of course the Lead Acid/AGM crowd. Virtually NONE of that knowledge is transposable at the test level, even the terms are divergent relative to which is being discussed.
Batteries like Driving your car.
Your speedo goes from 0-200 kmh. The car CAN do up to 200kmh, but should it ? Can it do that daily ?? Will it last 5 years or more if you do ???
If our reasonable and stay within limits <110 kmh and don't Pedal Mash at every stop light, you'll get a long low maintenance life. Even better if you drive an EV ! (10,000 less parts to fail LOL)...
Be good to your batteries, use them within THEIR Working Specs for the specific grade & type of cells and you will be happy for a long time.
