Ok, found a pic of a hecell 4000 mah cell. The numbers on it look to be just the same as a maxamps cell. So I guess that you can buy the same cell for almost half the price. Wow, maxamps really are a great deal! NOT!

I wish I still had the pics of the maxmaps cells that I took apart. I may have it on my pc at work, and will check tomorrow.
