More Mah the better?

[Dark Knight]

i understand mah is like a fuel tank. the bigger the longer you will go. but does it give more power? i just bought a 2s 610mah 20c lipo and im worried it will fry my stock gen1.

MAH is nothing more than capacity, and you really need to start searching, nearly every question you have asked has been answered time and time again.

i search but i never get the answer i need

What voltage is output by your new batteries? Thats the only thing you need worry about when it comes to frying the board via batteries!

I used to run 1000MAh 1.2 Volt AAA's and they kicked a$$ - never had any problems with them and if I was being honest I would say I preferred them over liths!

7.4v, its this one

that is much bigger then you need.
not too mention lower Mah.

pay the extra $5.00 and get the 700Mah 3.2 AA cells or, i can wire you a set w/ the board plug for $15.00 +shipping.
total 1400Mah for less weight with the same voltage AND they take up less room.
the only thing is, you would have to solder the board plug to your board and you waould have to solder one of the wires to the batt. side plug after you got it in place.

i cant do anything about it since i bought it now, but will it make my stock xmods faster?

[madcat303]

wont make it any slower

[Dark Knight]

i think my gen1 can go 40mph with this battery and a stage 2

lmfao...if you get an xmod to go 40 mph with a stage 2 motor then i feel like a moron for buying an atomic T2

[Dark Knight]

40mph lol, no more like 29ish

[bondo]

your going to hate that cell!
610Mah is less then one of the lith AA's.
i think your going to learn real quick as to who to listen to when it comes to upgrading your performance.

madcat is NOT a trusted/advanced member and he seems to be the only one telling you to buy it.

bottom line, that battery is crap for these cars....

i mean, serious crap...for these cars....

i do and dont agree with bondo. i wouldnt say that you're goin to hate it sense i have a lipo batt with 700mah 15C that was $12 and it lasts more than long enough with a rs s1 or s2 motor. but that battery just isnt a great one in the first place and you need to seperate the cells on it to use on a gen1 anyways

thats only 700MAH not 1400. to get 1400 you have to run them in parallel but only have 3.7 volts basically turning ur car into a 3 cell

no you dont have to separate the batteries on this pack. my only problem with this is going to be how to wire it into the xmod system seeing it is a three prog plug with safe charge. Heres what I would run in your car.

I run two packs in parallel on my titan and will run pretty fast with a stage 2 motor. here it is

keep in mine dark knight that without at least a 2x2 fet upgrade you put ur xmod at risk of blowing the stock fets.

@xmodsnut
just a question, if your running a stock motor why do you have to upgrade your fets when you go to lithium? every where i have read doesn't require it. and i have run a 6 cell set up and had no problems with stock fets. and I'm getting ready to run lithium, on stock fets. every response that i have seen when people ask if they have to upgrade fets to run lithium says no. so why has it changed now?

i just bought the atomic chili motor for mine along with 2x3 stacked, but i havent tested it on a dyno yet, im estimating around 30ish.

[benoj]

i have never had a problem with my stock gen1 with lipo. its fets only started to get warm after a long run. and for dark knight to use that pack on a gen1 you do need to seperate the cells b/c it wont fit under a body unless its very thin

go look at the stickied blown FETs story thread at the top of the electronics forum. you'll see why.
even with plain stock, you can still blow your fets

it just says its good insurance. and binding issues, and things like that. i guess everyone that says you don't have to is wrong.? i have run a 6 cell setup on one of my chassis for a long time and the lithium is only .2 volts more. i guess i've just got lucky?

The blowing/frying of Fets is based off of the amp draw to them, not the voltage. The amp draw does increase as the voltage increases and under ideal conditions a stg1 or stg2 motor will be safe on stock elec. with lithium batteries. The problem you run into is less than ideal conditions.

Xmodsnuts, for example, is using a rather heavy battery set up. The heavier set up is going to add more strain to the motor, the more strain or load on the motor the higher the amp draw goes. This is where it becomes unsafe. Binding in the gears causes more strain in the motor, towing, pushing, trying to get unstuck or anything else that adds more load or strain will increase that draw from the "idle mark" for lack of a better way to say it.

So yes and no. If you use a weird/unorthodox set up like XMN then updating your FETs is probably a good idea. If you have a six cell then you are fine. If that makes sense.
