Who should i contact if i have a defective part that came with my Henglong tank from Motion RC?

[Slurve]

The battery that came with my Henglong tank from Motion RC is apparently dead. After charging on the stock wall charger for 5 hours it still reads 6 volts. Who should i contact about this faulty battery or what can i do to get it to charge? Thanks!

I just got 2 tanks. I'm really testing with just one now. In my case, both chargers died while charging the lipo the 2nd time. If you don't get a green light when you plug the charger into the wall (no battery connected), then the charger is dead. I'm just using my regular hobby charger. Be sure to set it to LiIo (4.10v), not LiPo (4.20)
