Dual Cell Mod Tutorial And Idea!!!

[Snake Mod]

Either my searching is bad or is there really isn't an actual thread for dual's.Anyhoo....


Let's start with the basics, there are two kinds of ways to set up your batteries:

1) Parallel, in which + goes to + and - goes to - . It sort of acts as one battery, so the voltage (power) stay the same, and the maH (runtime) double. Sounds good and all but if power is what you need, then we turn to door number 2!

2) Series, the most common set up for a dual cell mod. It's when the polarities are + to - and + to -. Now that we've switched the batteries, they don't want to blend the maH together, but the voltage is increased intead. (Note: you must use the same batteries or you'll get a distortion on how it runs)

Here is an example that i'm not too impressed about because it just looks like a mess but the deed is done non the less. No offense to whoevers pics i got off this site . It may look familiar like your's as well.

Ok, I'd like to say stay away from the solder, It's bad because you can cause battery damage during the soldering process. Also after a while a battery will lose its charge and youu have to rip it out anyways. What's the point of using solder if you can't change the battery without ripping out a wire or two? Well...here are the piece's.

Tell me how this is!!!

how do I charge the car afterwards. I mean what batteries shoukd I use. I'm thinkin 9v but I don't wanna fry my car. I've tested it with 2 AA batteries on an external chargr but an hours worth of charge gave me only 4 minutes of play.

Don't charge with a 9V, you'll be wasting way too much power from an expensive battery.

You could charge with 3 AAA's for like a minute by direct connection if the batteries are wired in series. Charge with 2AAA for 1.5 - 2 minutes if they are wired in parallel.

You could also charge it with a zzmt remote since zzmts are dual celled, again if it is wired in series.

so is the tutorial good? I just thought since no one else put up a tutorial. The batteries that I use for my Motorworks is 1/3 AAA 160 Mah NiMH. The best possible yet of that size that i know of.

oh sorry here is a pic

So it looks like you're using brass plate for the added connection? Your Series/Paralell explination are a bit akward, but should be enough to get the point across to new people. What's that spacer looking thing you stuffed in the back of the tub, and how come you didn't install your other battery lead?

Overall it's a pretty good tutorial, though it's a little lacking on the writeup. I probably would add that it's not nessicary to rip all the guts out of the chassis unless you're really afraid of breaking the magnet wire, and that in addition to the chassis mods, it will be important to flip the PCB over for clearance which will require some PCB Cover modifications if you plan to keep one on there.

Charging is probably best done off the TX of a ZZ-M, Oval clone (with 3 batts), or a modified (to work with 3 batts) 4 AA or AAA battery holder like you can pick up at RS. Charge time of around a minute since like always with these cars, you're charging it at WAY over the reccomended capacity.

And I might mention that if you felt like it, while you've got the steering box open, it's not too much more work to give it some suspension travel like a Bit or Zip. It'll give you a little tighter turning radius, which was drasticaly needed atleast on the older generations of MW.

thanks I take it the tutorial is good enough. How 'bout I just have them read what you put down instead lol. Oh, I had 2 batteries of that kind but buffalo beans(member) is using one of them so i could only get a picture with one in it. The little thing in the back of the tub is a piece of balsa wood. I get 2" inch samples from Home Depot.

Here's is one that almost looked like my idea, but once and once more the damn solder showed up again.

mustve took a lot o work but otherwise, nice job

[Snake Mod]

thanks and remember no solder on the cells
