- 400A vs. 100A. Quoting burst discharge for high drain LFP (61C) vs. sustained NiMH currents (15C).
- NiMH 70% efficiency - true when looking at 0 to 100% SoC. In the 40-80% SoC normal operating range of the Toyota hybrids, they have near 100% Coulombic efficiency.
- 3X EV range. Might be true. Important to know that this is accomplished by consuming more of the capacity of the LFP battery resulting in a greater DoD and higher cycle wear.
- Lower voltage drop is related to the prior item. Yes, it's a performance advantage, but it comes at a cycle life cost.
- "Real results from real people" - who? Just a bunch of text on a screen.
- "No toxic fumes" - While arguably the safest Lithium chemistry, claiming it is safer than NiMH is a stretch. The electrolyte and vapors emitted from failing/malfunctioning LFP are extremely dangerous. Vapors will mix with the moisture in your airways and produce hydrofluoric acid. Electrolyte in NiMH is POH and KOH blend. NONflammable, NONexplosive but HIGHLY caustic (very strong base), but not inherently poisonous. Gases produced from NiMH are hydrogen and/or oxygen. Conveniently fails to mention that NiMH packs haven't had vent tubes on them for 10 years.

Ya, some of those points I already knew. I also learned some too, so thanks!
From what I can tell the guy is quite the amateur who exaggerates a lot in an attempt to convince everyone. It does seem like he might be hiding something and trying to cover it over with exaggerations. Or he's just exaggerating to try to convince everyone.
But in the end, I don't see any real advantage of his product unless it had more capacity. If the lithium battery has less of an internal resistance it may soak up and let out more of it's capacity than the NiMH. But he doesn't explain how he knows that for sure.
