Batteries getting to hot!

[rcracer_xxxt_futaba]

After I got my D4 11x2 the batteries would get hot enough to melt and come un done. :mad: :mad: . It's not how bad I solder though! The solder connection broke from a new *Deans Pigtail wire! What would make it so hot? The Timing on my motor is 17°. I run it for about 2-4 mins. If I touch the battery and speed control plug its VERY hot. :eek:

HELP!

Dude, like I said in another post, gear down that thing! It's pulling too much current for your system. THAT is the problem.

<h3>OK</h3> How about 16-17/88???

[Nairb]

Dude, maybe you should check your owner's manual for guidelines for gearing and things like that. Guess what it says? For an 11-turn modified motor, they suggest you start at 15/88. See what I've been saying? You were geared WAY too high before.

Lower the pinion about 4 teeth, like a 13 or 14 tooth. The D4 is hand wound and will be faster, and hotter. Gear down a LOT like Nairb said

[pmpnep]

what about my batterys then. my book says i should run 18P. I run 17P and there super hot. I use a 13 double motr.

Well it kinda depends on which ESC you have because an entry level ESC will get hotter much quicker than a proffesional ESC. Check your ESC manual it probably says what the limit is. But like everybody else said gearing down will help alot.

I have a Novak Dually, 2400 batts, and 11 turn motor.

The reason I started out with the 18/87 gearing was because thats what Adam drake said.

Thanks ALL!

Never listen to Adam...he's a gas truck guy... j/k :)

Your batteries may also be heating up from the memory that they have built up just from running the amp draw of a stock motor.

As for the suggested gearing, when i had my D4 14x4, i used a 22 tooth pinion, and it was fine, it gave me the top end and the punch i needed, i mean, matt francis' runs in the 22-23 on the buggy with a 12 turn, so i guess that 17 should be ok.

XXXER- Is that for a truck?

Im going to try the stock setup. 15/88. Then one I thought up. 14/87. But still. I think I would like a 16/88. I ran my 9-turn at 13/88 and it was fast and not very hot!

That was buggy, but taller tires cannot account for 6 teeth under, there is something up, that is all i have to say

[noobie]

xxxer - in addition to the taller tires is the extra weight. buggy to truck is about a 4 tooth difference on our track, depending on class.

I guess you are right, I never thought about that. Hmmm.
