Im planning on getting a couple nice stick packs for a starter box. Ive heard that the venom 3600's are good but does anyone have any other suggestions?

Also when I was looking on a website about the venom 3600's it said this and i dont really understad what that means...

"REQUIRES: Charger: Having Negative DeltaV or Zero DeltaV Peaking capabilities"
-Does that mean it just has to be a peak charger?

Thx
