The Layman's Dual Cell Mod (tm)

[JackD]

This is a great mod !! I've done dual and triples on both bits and zz's. The speed increase is awsome, especially for my zz, which I think are total slugs out of the box. My gripe is the run time is way too short. I blew up a button batt using a 4 batt charger to charge my triple. I'm going to try 6 batt charger next to see if that makes a difference.

Hey! I think i've found those batteries in radioshack! it says no for stores, but i think they can order it. the amazing thing is that the mah is 170-280! the only downside is that they are expensive (very). There are 4 different ones, w/ different voltage, mah. Check out the link! This could mean amazing speed + runtimes, if you're willing to pay.

WRONG... those are pretty big, dude. I think they're like the size of a nickle or penny. Way too big.

hey, i know it aint an original idea but i done a layman mod logo that i intend on usin so i thought i mite share it wif u guys

This may sound crazy, but is it possible to do a laymans quad-cell? I want to take 4 of those cells, hook them up, and place them somewhere (probably not the battery compartment, too small), and get 4.8v. it would be tough to charge, but just think of the results!

Yeah, you can fit a fourth cell in the chasis if you try.

I did a Layman's 6cell. I wouldn't recommend it though.

[Spongebob]

Wouldn't that fry the ESC? How did you charge it? I thought the PCB could only handle 6v. In that case, you must have had a melted chassis. lol.

[chelboed]

What ESC? These don't have an electronic speed control, they are either on or off. It didn't fry it, but it did make the PCB a bit warm. I didn't care for the performance at all. I got better performance out of a 4cell. It's just a bit too much juice me thinks. If you are racing on a real track, it is rediculous to even try to use a dual cell. I use my new MS Pro and still have to slow it down or it will spin out or flip. These new ones are fast with a different motor.

Anyway, for drag racing, 4cell is probably the most you'd wanna go.

I have been readin over this thread (mostly skimming) and would it be possible to use your normal unrechargeable watch batterys? I tried, it was a quick and messy job, and it didn't work. But I am sure it would.

And, would you be able to recharge an unchargeable battery?

[Spongebob]

Sorry about that ESC crap. It was kinda late and I was thinkin about my Dynamite Rocket Racer when I wrote that message. Is a Layman quad faster than a tri? is a tri faster than a dual? (when it doesn't have the performance "drop".

[xatu]

Most people have said that more than 3 or 4 cells makes the car run crappier. 2 cells is enough for me...

You know your car is fast when you have to run to catch up with it

[chelboed]

My own personal experience say's that 3cells is great for Drag's. My motors didn't run any better with 4cells. Some motors do run better with 4 cells though. It just depends on your motor and PCB set-up. Just experiment with it.

[JackD]

What motors work best in dual/triple/quadruple cells ? I replaced the stock 3.0 in my LXX booster dual batt with a zz red (2.19) motor and the performance improved significantly. Do the lower rpm higher torque motors work better with multi batts ? Or could it be that the the LXX 3.0 motors just suck real bad.

[xatu]

Use a lower torque motor in a multi cell car. They give great off the line starts, and have awesome power! My 2.2 in my dual cell shen had plenty power enough for me. Soon, I will dual cell a car with a 1.0 motor in it.
