i need some dual cell help.

[NOS man]

ok... for the wires i hav to solder on to the batteries can i use number 22 enameled wire?
and is it good to put a dual cell in a booster microsizer pro with a 4.2 motor? will it do anything bad to the car (for ex. i have to count the 45 seconds or the booster wont work)
will it improve speed or runtime or maybe both?
this is my first dual cell and im kinda nevous ill mess up my ms pro.
so can someone help me?

4.2 with dual should be just fine. The car can actually take more punishment then that. They make 4.2 pros for the 2 speeders. If you use a regular 4.2, then I would recomend not using the 1/2 speed function, because it can mess up the motor. The 1/2 speed works by voltage pulsing. Most micro motors aren't made for that. Just keep the car at full speed as much as posible.

As for wiring, I dont solder. You can screw up the batteries if you're not carefull. If you're not fast enough, you can even make the battery explode in your face. I just wrap the batts with electrical tape and sneak the wires under the tape. Depending on how you position them in the chassis, you'll never have a problem. Use copper. I usually just cut a slim piece of electrical tape big enough to wrap around the battery once. Electrical tape is very good because it's insulated. You may be able to use some shrink wrap or something too. Never tried that though.

I have a question. What about super glue or apoxy?

but would #22 enameled wire work?
would i have to time my charges?
would the booster still work?
would it increase speed torque and run time?

for the glue...i dont know

Well, I've never used #22 enamled wire, but if you're talking about different options of wire to increase motor performance, then it gos something like this; copper plated, solid copper, silver and then gold. Gold being the best. It has the least amount of resistance. I use solid copper. Gold is somewhat expensive.

Also, if I can offer some more advice about lowering resistance: The contacts that connect to the motor can be trimmed and the wire can be resoldered closer to the motor. It will make it easier for motor placement too, since you wont have as much resistance between the original wire and the motor. It's almost the same as hard wiring, but this way you can change out motors without resoldering.

About your other questions;

Charging: Check the threads on bit science. There's some good info on there. I use a modified digi-q multicharger to charge my dualls. Digi-q makes a charger that charges four cars at once. You'll have to find something different for tri+cells though.

It will work with a booster car. I was only saying that it's not good to run a motor in unboosted mode unless you have pro series type motors. Tomy motors and other motors can't handle the voltage pulsing very well. It will kill the motors fast. A booster car is just a 2 speed car. It doesn't go any faster then a regular one speed car. What it does do is it breaks the voltage up into pulses when it's unboosted, so it doesn't get a steady current going to the motor, in other words it gos slow. When you hit the boost button, it operates like a regular 1 speed car.

As long as you wire the batts in series and have good connection it will go much faster and have more torque.
