What zapper are you talking about bro?
The turbomatcher isn't a zapper- it's a matcher. It doesn't do anything to enhance the cells it simply gives you data on the discharge of indiviual cells.
Here's the skinny on battery zappers- the ones you can buy that are affordable are simply maintenance zappers. They do little other than occassionally bring back cells that start to go flat, and typically only help them for a short period of time.
The zappers like Danny at SMC use are custom built to his exact specifications (which are secret) and costs thousands of dollars. In fact, I haven't asked him personally, but I understand the cost of his current zapper would buy you a new pickup truck!!
For those of you who want to know Danny's personal suggestion for battery packs, here it is: Keep one or two of your current packs that are beginning to get flat, short runtime, etc to use as a first-run practice pack(s). Then buy two or three decent packs. Even if you run at Trackside or Cleveland where there are lots of great drivers (The Gate is Mike Blackstock and Paul Cicarillo's home track), you really don't need the best batteries out there! Just get two or three $60-$70 packs from SMC or your favorite battery supplier and run them 2 or three times per race day. Don't try to depend on batteries to win the race. Rather, work on setup and consistent driving skills to win races. Then, when your packs begin to feel flat, give your old practice packs to some newbie who will think you're the coolest guy at the track, demote your race packs to practice packs and buy two or three new packs!! This keeps you in fresh batteries which is the most important aspect when it comes to race packs. If you buy six or eight packs at a time and run them all the same amount, then they all go flat and dead before you want to spend the money to buy six or eight new packs!!! This came straight from Danny!! I know it sounds like he's cutting his own throat by telling racers to not buy so many batteries at one time, but that's the type of business man he is- honest. He would rather have his customers get faster and spend their money smarter so they will know who they can count on and believe opposed to customers who buy some stuff and never come back. If that weren't true why would he be matching at 35amps where the numbers "seem" to look crappy?
