Source of 5S LIPO batteries

[DoubleTrouble]

Does anybody know of a source of 5S batteries with overnight delivery?

Just found out 2 out of 3 of ours are reporting "low cell vol" and are not responding to the trickle charge trick. And we're off to Insomnia Friday.

Thanks

You might be able to get optipower to send some. Best to phone them up and let them know the situation.

All sorted. Thanks for the idea.
