HIP HIP HOOREY
This mod rocks, but i have an idea , i have seen people w/ stock batts 2 in and one out, think of howmany freakn batts we could fit !! and it wouldnt be NEAR as heavy. any body wanna try it with me ?? I figure 3 fits the size of one stock, i fitted 3 in my clone a little tiight but it works. so 6 on the inside fitting parallel to the wheels and 3 or more on the out side ! HOLY !@#$ w/ each bat kickn 1.2v each thats 19.8 now i think that would blow the !@#$ crap outta sumthijng haha cool concept though, maybe ill try 3 on the inside and 3 on the outside first !! haha damn that thing would be SMOKIN

HEY ACTOFGOD, I was just wondering how the tri cell is working in the booster car. I did not want to fry a booster car. Still working ok? Haven't burned it up yet? Thanks.

Actofgod....
Thanks for the info and reply. I will do my best to clean off all traces of the spot welded tabs since that seems to be my problem for sure.
Regards, Shanman

Alright, so i just read this for the first time... Goit a few questions.
Three of these little batteries will fit where one normal one would fit before??? Thats crazy!! (but wicked) I have noticed that the dual cell on a bit has been very popular, the one where they have one battery inside and one slightly on top and outside of the shell. Would your triple "mini cell" battery mod be better than say that one???

yes, when they put the batt n the outside (sticking up from rear window) this creates a higher center of gravity, and makes the cars roll easier and do wheelies. i did this on a Bb (had it under the shell near the center of the chassis on top of the pcb) and i couldnt stop that lil bugger from rolling, mind you it made for som egreat fun (for about 2 hours) then it justgot annoying... my new car has two standard size batts under the pcb, and i can fit the s2k shell on if i want (currently useing a gloria)

So what is better, to go with dual standard size batteries under the pcb, or triple mini batteries under the pcb???
i really hope i didnt totally misunderstand something, heh

well i have two 70ma batts under my pcb (pcb cover doesnt fit on it anymore) but its still just 2.4 volts, if you put the 3 mini batts they are 40ma (shorter runtime) but its 3.6 volts and lighter. but if u have the options, dont put anything like a batt above your pcb, it just sucks

either way youll need to make a custom charger 2AA for each 1.2 volt cell is the way i work it.

Hi,
I made already my 3x1.2Vx40mAh time ago on my Booster.
For charge I use a Clone TX with a DC power (I have 300mA,500mA,800mA available).
On my test I never been able to run my booster more then 1m30sec , for this reason I came back to my single 1.2Vx120mAh.
The best motor for 40mAh cell is the Bit 2.2, the other draw too much Amp, and as result the cell drop a lot of Volt, so a more powerfull 3.0 has no advantage !
At full speed the Volt between my 3cell dropped from 3.9V to 2.8V.
Full speed has increased to 13km/h from 11km/h (not a lot !)
I don't have a professional charger, so I don't know if I can get more out of it !
Anybody elase has made test on 3x1.2Vx40mAh ?
e_lm_70
P.S: It look to me that the best is to make a 3x1.2Vx80mAh, using 6 cell, 3 in series with the two group in parallel, as result there will be more juice for the motor and more running time ! ... but need some space on the car !

oh geez e - i never thought about it but your absolutly right, you could just make two triple batt packs (in series) and wire the two batt packs in paralell.. its such an easy idea.. why the hell didnt i think about it lol  i wanna try it now...

so what exactly can you expect from this mod? What kind of speed increase and average run times with a 2 or 3 cell?

What I tested:
3x1.2Vx40mAh (3 cell) - > As previous msg: little bit more fast, much shorter run time ! (Could be better with run time with a professional charger and longer charge time ... does it deserve it?)
3x1.2Vx80mAh (6 cell) : never tried, but could be with very good result ...
On a Clone (little bit bigger inside place) I have forced in a 2.4Vx100mAh single special cell (16x14mm) ... doing some body cut and soldering : result long run time little bit better top speed (on a Clone the powergo in noise instead of speed), huge range.
P.S: As my experience it look like that keeping two or three cell inside a "stand-by" car for long can make far more damage to the cell then with a single cell, since there is no power off switcher !
PP.SS: Got for 25$ here in Austria a ready clone, with turbo and 2.4V ... just little bit bigger then a Bit, with crappy tires, but replaceable with good Bit tires ...

tried 4cells, two two-cells in parallel...
basically, with some creative wiring,
i have three cells under the pcb and one cell on top.
Didn't want to screw up my bit so tried this on a LXX...
result - (for me at least) i saw slightly more runtime and
about the same amount of power as the regular two cell mod.
Thing is, with one cell, i still couldn't properly fit the body
onto the chassis.....
i'm sticking with the two cell mod and 2.2 motor for now.
I didn't see too much more run time with the cells in parallel...
(though i didn't peak charge them)
...
QUESTION though: how does the two button cell mod with
2.2 motor compare in terms of speed and torque with the
upgrade motors? like the r-spec or 3.0 and above?
I'd really like to know if it's worth it doing this two cell mod
or better to just get a faster motor with a regular 1/4AAA size
150mah battery.....
