You guys did great.

You guys did great. The replacement battery is just what I needed for the drag racing I'm doing and the T-shirt was perfect. Thanks so much for your flexibility in swapping out one battery for what I really needed.

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.
