We should compare apple with apples here! The pack in question from Batteries America does not use Sanyo cells. They are some 'Private Label' cell. Now they may be good quality cells, but how would we know?

The 1650mAh pack at Radical RC does use Sanyo cells.

Also the Batteries America website is horrible.......it loads a huge long page with all of their products on it and you have to scroll slowly through it looking to see what they have.

I am not knocking or praising either company, I just think we should do a fair comparison.
