Need recommendations for my spartan. I have a leopard 4092 (hot motor) with a seawing ESC and an Ocutura 443.. Last year, I was running the Traxxas 8400 packs but sadly, all of mine have discharged and are fairly useless at this time. Should I stay with the Traxxas packs or move to something else? I see that folks like the SPCs and Gens Ace. Any recommendations that you have (manufacture and mah are greatly apprecaited.
