okay i was a wiz at nitro but now i bought myself a e maxx and have couple a questions about batteries. first how long do i charge them the first charge because theyre new batteries. this is the ad http://www.rcuniverse.com/market/item.cfm?itemId=465143 also how long does it take to charge them? the seller told me 30 minutes the first time for each pack but after the first charge they take only 20 minutes to charge? also how long do battery packs usally last?
thanks alot in advance

They will not charge in 30 min. Just get yourself a Peaking charger, and it will automaticly cut off when the batteries are through charging.
