Best brand of 1500mah 4s batteries?

Recently I tried 1500mah 4s 100c Lipo battery for new brand RCHACKERS, so far these Batteries are Great… They are great for the Money I spent.Perfect fit for my SG 1603. Lots of power! I run RCHACKERS batteries on several of my vehicles and quads. They never disappoint!
What other brands do you recommend?

4s gnb all the way. gnb 6s, not so much

looks great. I will try a pack or two. But the price of the 1550mah 4s is not an advantage over my current budget lipo battery, Ovonic 4s 1550mah. You can compare them.
