While the weather here in Ireland is crap atm I'm looking at adding upgrades including chargers etc. I'm currently running two 3s traxxas lipos and have two 4s lipos ordered. Which would be the best Charger to go for please? I'm very impressed with traxxas atm and can't see me leaving the brand anytime soon. Based on this I'm happy to invest in a traxxas charger preferably charging 2 lipos at once.

Any advice would be appreciated.
