Good luck getting a new LiPo back from them. They've been backorderd for months now. And I forget that they're still a small company. It's gotten so bad, that I've been forced to buy LiPos from another company.

As for the case apperance. No, I've not seen anything other than the carbon coverd case LiPos. Seeing a black LiPo from thunderpower would be new to me.

Sorry to hear about your bad luck.
