battery question for mini-t
 
stock battery is 7.2v. I was looking at Radio Shack the other day and saw 2400mAh 9.4v, BUT the exact same size as the Mini-t cells. And they are only $10. (clearance)

will a 9.4 do damage to a stock Mini-T????

Do you mean 9.6v? That would be an 8cell pack. Dont do it, the stock ESC cant handle that I believe. Just get a nice set of Gp1100 or IB1200, they got em here for only like 12.99 a pack. They'd run much better than those cheapie packs

They don't sound like they deliver punch, you are probably better of with using a decent 7.2V pack! (like the GP or the IB's)

Here, perhaps you can do something with this;

I would use the new IB1400's.

Also consider a 2s lipo pack.
I purchased a Great Planes 2s 1500 8C pack over a year ago for my Mini-T. It works fine with the stock electronics. You just want to watch for when it starts to slow down, or better yet, get a low-voltage cutoff device.
Here's a link to the pack I got: http://www2.towerhobbies.com/cgi-bin...&I=LXGHE5&P=ML . Of course, this means you need a lipo charger, but if that's all you're using it for, you can get away with a $30ish 2-3 cell lipo charger. Heck, there's even a 1A wall charger for 2s packs for less than $10 http://www2.towerhobbies.com/cgi-bin...?&I=LXLGP8&P=7 .

My 2s pack also works great with the Mamba 6800 system, which lets you know it'll handle an upgrade to the electronics as well.

why for a mini-t the truck only takes low Mah. like 1500's and not 3300's know what i mean.

Gustav 06.16.2006 09:22 PM

They just don't fit that's all,mini batteries are mini.You'd still get good runtimes from 1500mah since they hardly pull an amps.

squeeforever 06.16.2006 09:43 PM

Yea, 1500mah is rather high for most mini trucks. Thats pretty good runtime to.

Sylvester 06.16.2006 09:46 PM

imagine if you could fit 12000 mah in there :);)

It's a matter of size due to energy density. Both nimh and lipo can fit a fixed amount of power in a fixed size.

Take IB (Intellect Battery) nimh, for instance. The standard sub-c size cell can hold 4200mah of power in that size cylinder. The 2/3A size cell is physically a smaller cylinder that will only hold 1200mah of the same power, simply because you can only fit a certain amount of power within a certain space.

If the Mini-T had the room to mount a sub-c size battery pack, you could definitely use 3300mah cells. It just lacks the physical space for it.

Hope that helps.

I know it's not the same truck but I've been running an 8cell in my 18T for about 3 months now. Not to say there is not going to be some issues but so far so good. Well except for that noisy diff.:005: Went from 27mph on the 6cell to 32mph on the 8cell.:027:

Mike.L 06.18.2006 10:18 AM

i just didn't know it was a smaller battery than sub-c.
i understand now thanks.
