Lipo´s - Maxamps 8000 mah or 6000HV

I´m thinking of getting another set of lipo´s for my E-Revo (Quark 125B and Feigao 7xl) but I can´t decide to go with 2s2p 7.4v 8000 mah or the 2s2p 7.4v 6000HV.

(I have a set of 8000 mah and they are great - but more pricy)

What is the difference (besides the 2000 mah and runtime)? What does the HV mean ?

Any advices ??

8K all the way!

no doubt. they deliver more voltage under load than the 6K packs. (differs a lot.)

Or trakpower 4900 packs. they hold 7V per pack on 100A load.
