I am looking into getting a charger and I am looking for opinions:

first I want to know if I can simultaneously(sp?) charge two 6 or two 7 cell battery packs if my charger says that the limit is 15 cells

I want to charge two at a time because I have an E-maxx and I dont want to charge one then charge the other

also would there be any benefit to charging them together, would it take twice as long?

the chargers I am considering are:

TLP - X15 Digital Charger/Discharger

Venom AC/DC Pro Charger

I like these because I wont have to buy a DC power supply, and they both support lipo (I would like go lipo in the future)

any help with this decision would be greatly appreciated
