lol, nice slip Aaron.

[jamiekulhanek]

Muahahahahaaaaaaaa. Where did u get these tyres/wheels/whatever??

Mini z stock have zero traction……..

[Shypo]

i want sum low profile tires, i have had my Z not evn 6 hours and the tires are already pretty burnt down lol

Yeah shypo, drifting and doing doeys is great fun huh. I reckon the tyres on the mini z are damn low profile, what is it that kitty is talikng about.

The world is mine

[PandaBear]

Kitty’s low profiles must be pretty furry by now, if she still uses the mZ to chase her pussies. :blush:

[Shypo]

LOL at Panda, i lo0ve drifting i my Z, just boguth some new Batterys from Jaycar. 650mah

Aren’t 850mAh AAAs available here yet?

I had opportunity recently to discuss with several battery wholesalers/distributors in Asia, into the conversation fell details regarding the stuff that certain Oz chainstores sell for cheap.

When a factory manufacture a cell, even with the tightest quality controls you will still get a varied range of quality coming out the other end. What the company does is then *test* the cell, and then grade them according to specs.

There are various grades of rechargeable cells… highest is “Milspec”, then comes “Industrial” and then “Consumer – branded”. All these have to meet certain preset specifications.

Then all the remaining rejects get sold off too… usually as unlabelled cells of unguaranteed performance. Its not uncommon to find shorted or open-circuit cells within this lot; sometimes this refuse is even sold “by the kilo”.

In this industry, you get what you pay for.

that’s exactly how computer processors are done as well
it’s a cheap way to manufacture, cause there is only 1 process (instead of a 700mAh production line, 800 mAh production line) and also hardly anything is thrown out, it just gets labelled to a lower rating

Yeah, “best” out of a heap of brown dog logs perhaps. 🙁

[Shypo]

pretty much, i dont really know my batterys to well so i went with what a couple of people told me and the charger i have probably cant support anything over 800mah, i may be wrong but i dont want to risk it. plus those cells are damn expensive

Well if you call the rechargeable NiMHs doglogs, what do you call commercially available AAA Alkalines?

My charger tells me that my 650AAA’s are charging up to 900mAh, whether this is an accurate figure, I don’t know.
The cells get a bit hot, so I think the charger is telling me the gross capacity, and some of the power is wasted in the cell as heat, so the net capcity may only be about 650mAh.

I’m in on these Milspecs, i’m sure thay have very low internal resistance etc. sounds like race winners.

The world is mine

[PandaBear]

The charging-up figure usually isn’t too accurate, if your charger can cycle them use the figure from the discharging instead.

AAA alkalines actually work better than imagined in an MiniZ… they do pump out 6V total. Plus I’ve got a charger that can charge ’em, as long as they’re not run flat.

Am still waiting for Sony or Energizer Japan (not Mexico) to bring out some AAA batteries. Their AAs are great and longlived.

[jamiekulhanek]

SoAAA alkailines actually give more power, and how do u charge AAA Alkos?

The world is mine

[PandaBear]

Got some big grey box invented by some fellas in Melbourne that I put the alks into. Strangely it just does the job…! :shy:

Have tried quite a few different cells in it… from D, C, AA, AAA and even 9V and lantern 6Vs, even the lithium thingy from my Minolta.

Only catch is that the battery can’t be totally flat, its best to recharge often and > 1.4V. This way can usually get 10+ cycles from each cell.

The thing even signals if each cell is ‘good’ or ‘give up’ at the end of charge.

Zinc-carbons can go in too, but they seem to fail faster after only a few cycles. Alkalines do best of all the supposedly non-rechargeable cells.

[jamiekulhanek]

Hmmm im liking the sound of these things….

The world is mine

[me and me lude]

this sounds dangerous….
the reason they shouldn’t be recharged is cause sometimes the wrong reaction occurs… instead of reversing the reaction, another reaction occurs instead, this one involves creating hydrogen gas…. thus explosive

Ahh, all you doubting thomases… 🙂

Firstly… there’s not much volume inside an AA and there’s not much space for electrolyte. If it did gas, the volumes wouldn’t be much.

Secondly… err, I’ve forgotten all my highschool chemistry now but I don’t think charging a carbon-zinc battery will produce H2 by itself, as if it did it’ll be by breaking up H2O in the paste electrolyte and there’ll be equal molarity of O2 as well.

But yes – I charge my leadacid (“car”) batteries *outside*.

Have tried charging C-Zn cells in trickle chargers before (who hasn’t?) but all of them rose in voltage but they go open circuit too. Probably a good indication that the electrolyte has dried up.

Have no idea how the charger does it. Computer-controlled, so probably some kind of reverse pulsing is possible (eg 3 steps forward, one step back kinda idea). All a “trade secret” I’m sure.

[me and me lude]

heheheh ok
i’m not too sure where the hydrogen comes from
all i know is that reaction is easy to start then the one which recharges the battery
but if it produces O2 as well as H2 it’s even more dangerous….
not enough oxygen creates a fireball like effect, enough oxygen creates an explosion

and after it explodes you wouldn’t want all that battery acid and stuff on your face

Haha, its not a “reaction”, its just electrolysis of water.

Just get a beaker of clean water, add a little acid to it to
make it pass a current and stick 2 electrodes into the water.
Power them up with about 12V and lots of amps, and pretty soon
you’ll see gas bubbles rising from the electrodes.

I *think* you’ll get H2 from the +ve and O2 from the -ve; you’ll get twice as much volume of H2 than O2.

2H20 => 2H2 + O2

which is the perfect ratio for complete combustion back to H20. (Its just the energy you’ve pumped in getting released out, its a zero sum game.)

yeah i know about the electrolysis of water (i’m in year 12 this year, studying chemistry) but i don’t think batteries have any water in them

also electrolysis is a type of reaction:p

oh also i think hydrogen comes from the negative electrode, H+ ions that receive an electron

Hey People, i just got a new charger for AA/AAA’s. Im just wondering should you always discharge batteries? Both NiCad and NIMH or just one ? OR should you just keep topping them up?

I think your supposed to discharge one and not the other but im not too sure so can someone please help me out ?

nicds have a memory effect if u dont fully flatten them, so they need to be fully discharged.. NiMH have a reduced memory effect but i’d still recommmend flatening them before chargeing to prolong the life of the cell.

The electrolyte is in the form of a paste, so there’s some water. Its like gelcells… the acid is a gel, but its still waterbased.

Depends on your definition… I say its not really a “reaction” as you need to pump power into it to make it happen.

Makes sense, I’ll believe ya! 🙂

Cool thanks GT-Ahh … ill be discharging my nimhs then, what about alkalines? you know about that ?

Agree!

Actually I’d even say discharge them after using and store them flat. If you’re talking individual cells you can put a resistor across each one and flatten them to 0V and store them with the resistor still connected.

I also find NiMH has a higher level of self-discharge. If you charge and leave them unused, they’ll slowly lose charge by themselves but this rate is faster than a NiCd.

[Barrelll]

ok thanks alot for that .. what bout just topping up a nimh battery ?

SAy you only use them for 10 mins ? just chuck them in the charger for an hour or whatever ? os is that bad ?

NiMH will take quite a bit of abuse.

If you run them for 10 mins and not gonna run it again for a few days, then discharge them flat.

If you’re just about to race… then maybe you might wanna just top them up a bit.

Higher current charging usually makes them a bit perkier, compared to trickle charging. But you need a deltapeak charger to be safe.

[Barrelll]

Thanks alot for that = ) Yeh i had used my mini z for 10 mins then was going to race last night so just put em on the charger to charge them up a bit and they worked great. Only problem was that the mini z was too quick for the track lol

The MiniZ is fully-proportional – hint hint!

If you no wanna go so fast, you press the gas less!! 🙂

[KittyKatSmack]

More control, less lead in the foot

*like I am some kind of expert?*

*choke*

:smiley2:

[Shypo]

thats what i find the best thing bout Mini Z, you dont have to have fulll throttle like a digi q or a BCG

I cant resist pumping the gas with my x speed, no matter how small the track is. It usually results in destroying the body blackeye:

[PandaBear]

Ya, always run with the body… I’m still running mine naked and I think the front wheels are looking pretty vulnerable!!

Hmm… wonder if I can make some thick foam “car bra” thingys for the body I eventually get.

[Shypo]

i want a shell made entirely out of foam lol, white shells are good as you cant c the scratches as easily

yeh i know they are fully proportional, but you cant help but just press the button down lol, also it accelerates too quick, probaly due to upgrades tho, a stock car would probably go better.

About the body scartching, i brought a specialised body just for racing/crashing hehe = )
