If you want people to trust in this,
My point is not to run PR for BYD. I'm not trying to get people to trust a corporation. I'm just shutting down FUD (that is most likely rooted in sinophobia).
Basic physics knowledge? Why would we disregard that based on the word of a corporation whose entire goal is to convince us to buy their products?
Yes, I understand the basic physics since I am an electrical engineer and work in the automotive space, and I integrate batteries into battery electric vehicles.
Regardless of your stance on warranties, corporate competition, or China..... the original claim was "Seems like these batteries push more toward the speed and capacity side."
Where is the evidence to support this claim? For what reason could anyone think that BYD's design philosophy caters to performance over durability? That is just pure fucken FUD.
This happens all too often:
- An engineering feat is achieved
- A layman hops into the discussion to inform everyone about the concept of engineering tradeoffs (as if that is groundbreaking)
- The layman gives their uninformed opinion about why they think the tradeoff was ill considered
Here's the simple truth: BYD's entire battery design philosophy revolves around durability. If BYD was truly solely interested in battery density and charge speed, then why are they the primary champion of LFP batteries? If you were truly interested in performance and speed, LFP would be your last choice for battery chemistry. If anything, BYD leans more towards durability, safety, and longevity over performance - as is evidenced by their choice to make their entire design philosophy revolve around LFP. Teslas and Lucids lean towards Nickel Cobalt because Nickel Cobalt battery chemistry is fundamentally more performant than LFP batterys. THAT is "Basic Physics".

So, Who’s the Winner?
The answer isn’t black and white. Both LFP and NMC batteries have their strengths and weaknesses. LFP batteries trade off some performance for greater safety and longevity, while NMC batteries offer higher performance at the expense of some safety and lifespan.
The “winner” really depends on your specific needs. If you’re looking for high performance, especially in applications like EVs, NMC is likely your best bet. But if you prioritize longevity and safety—especially for DIY projects or energy storage—LFP batteries are the clear choice.
In the end, whether you go with LFP or NMC, it’s all about matching the battery to your needs. For most everyday uses, especially in energy storage, LFP batteries are hard to beat for their combination of durability and safety.
