Lipo smell?

[Gustav]

They're evo 20s direct from flightpower.All the packs i've had have this sweet smell from new,i think maybe it's left over smell from manufacturing.The one that was leaking properly (maybe damaged in transit?) was seriously pungent chemically smell,no way you'd not know about it.Also it was a darker shade of orange than the others,like the electrolite had leaked and soaked the orange wrap.
