At last, you mentioned that your battery is 6.8Ah capacity at 150A discharge, have you tested about it? Because i know even Panasonic can't make battery at such a high level, or even not close, that is far beyond the current ability of the world's NiMH battery technology, i can even tell many more basic concept mistakes in your judgement, i think you are misled by your "professional" supplier.

Sir, please don't insult my intelligence. I am well aware of everything you mentioned having to do with the separator (and plate) thicknesses. Obviously it's possible to produce NiMH D cells of varying capacities and current carrying capabilities. More capacity means less current - it's always a trade off between capacity, current and longevity.
Of course I have tested my cells. I have mountains of data. I've tested them at up to 70A of charge current from 0% to 100% SoC and at 160A of discharge current from 100% SoC to 0% SoC. I've tested them to 210F. I have cells that are nearly 2 years old - the oldest ones in existence.
Your own specifications state that your cells can carry 150A of current, so why would you question whether mine can? You're the one claiming that our cells are the same. Very confusing.
Anyway, let's end this now. I'm not going to continue arguing with you. I've stated my side of the story and I guess you've stated yours, so there we are.
