MaxAmps Lipoly 8000mah 2S2P 7.4V Pack
 

are the batts good how much run time will i get w/2 of these on my e-maxx quark125 feigao 7xl do you recommend these or others. are the a pain to charge i am getting a super brain

They are good batteries.... very good for the $$$.

Expect a goal of about 30 minutes runtime... probably more for average bashing and maybe a bit less if you run it really really hard.

I use the ICE and it works well... the new MRC looks pretty nice I must admit, if it lives up to the specs.

The Triton2 works well for me while charging...
