"
...capable of recharging a battery to 70% in just two minutes, yes: 120 seconds."
Such announcements tend to raise many questions in those interested in batteries. What is the capacity of that battery? How many amp-hours? How many cycles, years, and under what conditions?
Lithium-ion batteries are rather expensive compared to lead-acid batteries. For now, I'll stick with heavier (plate thickness) but less expensive lead-acid batteries for PV system storage (e.g., Crown deep cycle for scrubbers, golf carts, etc.). It's most often about dollars spent for amp-hours yielded and cycles (plate thickness).
