9-volt

[123Vette]

Can u use a 9volt on a evo car with 2x2 fets on it?

I want to no if this is better then rechargealbe and dont want to risk my car so i was wondering if ne 1 has done this be4.

P.S. i no lithium is best but i need to buy some

[mini-z drift]

I once had a Lancer with 12volts on stock fets!!!
the batteries were energizer rechargables!!!
But it died because it was going so fast it hit a curb and it went to RC heaven:( :cry: :( :cry: :( :cry: :nod: :o :nod: :o

No, you cannot. It would instantly fry your board.

FET stacks do not have anything to do with how much voltage you can put through your car. FETs have to do with the amount off amps that can pass through the terminals, to your motor. This does not mean you can pack 9V onto your car.

And if you decided to do it with a 9V battery, you would get such inefficient run times. 9Vs are not meant for applications such as RC cars. They draw way to much power from the battery, and the 9V wouldn't be able to handle those current draws. It would be dead in a matter of five or less minutes.

Sorry for the double post.

Rechargables go by intervals of 1.2V's. There is no way that you could have managed to shove 10 rechargable AAA batteries onto your Xmod, and still have driven it around. With the amount of weight from those batteries it would be literally pointless to have that many. Even if you did, you would have instantly fried your board. These boards are not meant to go over 8.4V's. If you can even manage to get 8.4V's onto your Xmod, and run it successfully, I want to know how you did it. And how exactly you wired everything.

[mini-z drift]

Mine were 1.5v

Here is my neighbors-(he copied me, his still works)

[Donziikid]

Those are definetly not rechargeable batteries. And besides, if his car is still running; I'm amazed.

[123Vette]

so no then?

[mini-z drift]

Yeah but he got out of his xmod in November 2006 and sold it on ebay for like $100.

[Donziikid]

so no then?

No, it will not work efficiently. If anything, get some extra rechargeable and just add a five/six/seven cell to it. Much quicker, easier, and more efficient.

That or Liths

[123Vette]

i can afford lith right now that y i asked

[Donziikid]

There's really not contest if you know anything about batteries.

A 9V is pretty heavy, when Lithiums actually shave weight off of your chassis. So if you have the money, go with Lithiums. No contest there.

this is what i did: 3 pack of AA's from a radio

the speed and braking cant be controlled but at least i can steer lol. hope this wont fry it. but anyways 123 this is what i did and i have had no problems yet.

[Donziikid]

Forget frying your board; let's just hope it doesn't explode. :eyecraz:

Never mix battery types. They will always try to charge one another and either seize, or explode. For your own safety, remove those AA's before something goes terribly wrong. :o

[123Vette]

I no lithium is best but im trying to find an alternate until i can afford some more, Anyone got any for sale? lol

[xmodificationer]

the batteries are hooked up seperetly to the motor

[lilskipro587]

I don't know whats up with kids these days. I may be 14 but I sure know when something either is or looks stupid. and putting a radio battery on your xmod thats stupid.

[xmodificationer]

hey but it flys!

[123Vette]

Yaeh it may fly but it will break it soon

[Stampedekid]

my g35 had energizer lithiums in it once, it drove so fast that when it crashed into the curb, the whole front bumper tore off! this is not a lie, i was drag racing my friend for $15 and he slammed me while trying to be funny, luckily my other friend was there and forced him to give me the money :D be careful with lithiums and a stage 2!

[Sweed]

Read through AtomicMods' FAQ. Good info.

The energiezer lithiums are BS. I have no clue were the Lithium comes in, but lithiums are 3.7v's (unless they are a123's which aren't made this small). ALL RECHARGABLE Batteries (unless li-po/ion) are 1.2 VOLTS each. Period.

Those are definetly not rechargeable batteries. And besides, if his car is still running; I'm amazed.

ph2t's crazy aus 11.1v board anyone?

[RedSXmodder]

crazy aus

Crazy aus! Hahahahaha....

Anywho, sweed, I've honestly never heard of a123's. Can you give me a desription?

Crazy aus? You can't argue that ph2t isn't a crazy aus, but he is really nice and helpful when you need it..

a123 is MIT's venture into batteries. It's a full start up company, they make car batteris, electric car batteries, and they're working on variable voltage batteries for RC's. I think the make Li-Poly (or similar voltage) batteries. Read about it in RCCA and some other 1:1 Magazines.

ACCUTALLY U CANT GO OVER 7.4V

[Sweed]

ACCUTALLY U CANT GO OVER 7.4V

It's 8.4v, atleast for the Gen1's. Not sure about the Evo's. Read the thread.

[modman54935]

evo are 7.4

[mustanglover]

so then gen1's are 8.4?? iam confused?

[modman54935]

supposely

[Sweed]

supposely

Gen1's can take a max of 8.4 volts.
Evo's can take 7.4 volts, some freak boards to 11.1 volts.

It's not like it matters, the Li-ions we use are 3.7 volts. The Rechargable batteries are 1.2 volts.

[Darkmagik]

Then why would lith be better than rechargeables?

[Sweed]

Then why would lith be better than rechargeables?

3.7volts and higher discharge rate for the weight of the cell. Less weight with more voltage is more speed. Logical to me.

And it's such a big speed boost and increase in run time over rechargables for the money. $15 for rechargeables and then $25 more for a good charger. Totals to $40. Lithiums and a charger are about $50.
