Hey guys!
I do not want to be a pain, or some ass here.......and don't get offended here, these are just "Toys" I mean "Hobby Toys"
Like some of you mentioned, if you're taking perfect lap after lap, then you may see the difference, but if you have the best # like 1.18+ or even higher #'s, when you're racing at your club track for braging rights, (That's cool), but remember this, the person that do not have the good #'s that you have and he's taking good laps after laps, then he will beat you to the finish. And also if you do not take good care of those batteries, you will loose alot of performance from those good #'s.
I know this one guy, he has 1.13+ and the best he has was 1.15+ and he's beating the person with 1.17, and 1.18, and he even lap the person too. So just think about that for a moment. I myself have 1.098, 1.124, 1.13's, 1.15's, 1.16's, and 1.17's, and I'm beating a person that have a 1.17+ against my 1.13's, and I'm lapping him too.
Just take good care of your batteries, that's my .02 cents.
