Hello everyone - I'm building a 250 quad and getting batteries from HobbyKing turns out to be a little expensive with the shipping and customs. Quadkopters.com has Lipos that have the C rating I need - but they are QK lipo, which I assume stands for QuadKopters.

Does anyone have experience with them? Are they good quality and safe?

Thanks!

@gulzaar they are safe and good .. although mine burst because of short circuit .it is a very good battery

These are A-Grade LiPo, good quality have no complaints so far.

I ve been using one since last one year, no prob so far. They are good.

Thank you guys!

QK lipo are so good. As i've been using them form last year and no prob.
Good discharge and current holding capacity reduce after ~15hrs flying.
