[size=+3]Molicel INR20700A 3000mAh (Gray)[/size]
Official specifications:
This is a high current 20700 cell.
The two cells tracks nearly perfectly, at the 30A discharge I had to stop due to temperature, but the cell do not look overloaded on the discharge curve.
[size=+3]Conclusion[/size]
Very good battery for up to about 30A, at the high current the battery may need a rest during discharge to cool down a bit.
[size=+3]Notes and links[/size]
The batteries was supplied by N-Power Energy for review.
