mah and runtime for racing 1/8 Buggy?

The place I race at also has 15 minute 1/8 buggy mains. I was able to go the distance with my Enerland / Poly RC 5000mAH 4S Li-Po. That is on a Neu 1512 2.5D and a Mamba Max ESC. When I charged up the battery about a week later, I put less than 4AH back in (3700mAH if I remember correctly).

I like the single battery setup to try and keep things light. Of course dual 8AH Maxamps is a great deal, but you do pay a penalty in weight.

The track I go to is a bit on the small side and with my original setup of about 39MPH top speed, I never maxed it out. I think I am about 35MPH right now and that is still plenty for the track. It doesn't seem like over 40MPH does much good unless you have extremely long straight-aways.

I'm also planning on running a single pack. I have an enerland 4350mah 5s pack that I was planning on running. According to my estimates I figured that that should be just about enough, but wasn't sure. I am going to buy a 2nd pack and was thinking that I would go w/ the 5000mah, but didn't want to take the extra weight if I didnt need to.

I am guessing that the 5s pack I have will be more voltage than I really need, but I am going to be running a slightly lower kv motor than you so the speeds should be around the same as yours. Maybe slightly higher.

Sounds like the 4350mah will be really close. I guess I'll have to take it out for a practice run and time it to see how long it runs before I buy another pack.
