YeaH but Smc now wants $12 for shipping. And they get way out of balance during use. Sometimes mine are off .30 volts of each other. And I've had one go bad with 2 months use Because of that.
I will never buy a hard case turnigy or gens ace again. Their leads tear off the cells from vibration. Requiring special solder only found online to fix at an astounding $30 + shipping for a small roll of it.
A friend of mine had 2 hunger batteries and I think he only used them 2 weekends in a row and they went bad.
Check out kyosho's batteries called peak. I bought one last weekend. They're pretty inexpensive. And seem ok so far. Time will tell though. It also doesn't seems to have the same punch as my Smc does. But I've heard some say Lipos tend to get a little better after a few uses.

Stick to batteries with higher C ratings like 50+. The lower ones really lack in power delivery you can notice significantly if you run them back to back with one of higher C's.
