Killavolt quest glitch?

[Ed]

I've collected all the tokens, and collected all the batteries. Next step in the quest is to talk to Moxxie. I've talked to her both in the city and on Sanctuary, and all she says is "are you still working on that little job?" According to what I've read elsewhere on the net, Moxxie is supposed to accept the batteries to continue the quest line.

I've restarted the game a couple times, same result. Suggestions?

Normaly she crafts a spezial token with the batteries,after she gave it to you ,you goint to fight killavolt.only works at moxxie in the city

[Komarimaru]

Can only be done in the city where you gather the other tokens.

I have everything and need only to speak to Moxxie,but no option to hand over batteries. Its the same for me , cant finish the quest . Any sollution for that ?
