This is the latest 20700 battery to hit the market. 3000mAh from Efest.

They give better performance up tp 30A pulse discharge (5 second pulse ay 30 second intervals) than most 18650s, but are a long way behind 26650.

But compared to VTC6, there doesn't seem much point in going for the bigger battery form. Here's how they compare at 10A pulse discharge:

At 20A:

And 30A:

But they do perform marginally better than IJOY 20700 in all pulse discharge tests and continuous discharge tests up to 50A, but the IJOY performs better at 60A continuous (I just can't think of any applications that would use 60A continuous).

Oh, those 30A and 40A capacity figures might need editing? (or explaining?)

Legend may be pushing it a bit.
Well whenever the conversation of batteries ever comes up in my local B&M or online, it's only a matter of minutes before either you or Mooch are referred to as the main knowers of everything. So Legend in my humble eyes. Welcome to POTV :2thumbsup:
