My first set of 2S 4000mah batteries. Lightweight small and fits my UL-1 Hydro. Was able to reduce my lap time by 1 second over the previous batteries I used. Thanks.

Awesome pack, this is first experience with lipos. I will never go back to anything else. Long run times, less wieght, more power what more could you want??? I easily run two qualifiers and sometimes the main on one charge in our brushless B4. Thanks MAXA...
