So Chargers for twin pack Lipos

[BRS]

Right I have bought a Caster Truggy for the son for christmas, I have Lipo's on their way (bloody hope so anyway).

The truggy will run on 2 x 1/10th packs (7.4v 5000mah 40c), what chargers are available preferably that will charge both packs at once from 12v outdoors or 240v at home?

I do have a good Prolux charger that I use for my nitro rx packs that will charge Lipos but if he comes racing with me need someway to charge him between heats.

Thanks
