Are 9918 warrenty protected?
 

Just incase i burn out the 9918, will i get it refunded? My setup should be good (motor won't pull too many amps for esc) and i only run about 4 inches of wire...but what kills me is that battery bars (i run side-by-side 16 cells) actually count as wire! That means on 16 cells it will almost be impossible for me to get under the maximum wire length (the schulze wire length has to be under 20 inches)
Soooo,
each battery bar is .75 inches,
18x.75=13.75 (18 battery bars total, times .75 equels total battery bar length)
13.75+5=18.5 (Total battery bar length plus actual wire length between battery and esc)
18.5+6=24.5 inches!!!!! (total battery-esc length plus 3 2 inch wires connecting the motor to the esc)

Why are you counting the battery bars as wire length? I am not an expert but when a company says the maximum wire length should be 20 inches, I am thinking from the batteries to the controller and not include the bars.

for maximum cable length, it includes battery bars. It's so stupid!!!

Battery bars aren't that long - you can't measure the length of the bar - but where the solder actually touches the bar. The actual bar length that's not soldered is probably closer to 1/4 to 1/2 inch. You can always go around this by direct soldering the batteries together with a T solder head.

I don't really understand what your saying, read this

Yes, i know what you mean, BK says that.

Lipomax means that you don't need to use the TOTAL length of the bar, because the solder also can travel the energy. (so from solder to solder point will be less then the total bar length)

SOldering the batteries toghether with a T-head, will make you a stick-pack, it means that the battery-poles are soldered DIRECTLY on each other.

If you take a look at Candyman's MAXXbling, you can see he also uses side by side batteries. Ryan on this forum also used side by side batts.

I have a 7xl and 9918 with 18cells. no problems so far with controlor. But I will be adding a fan. Better safe than sorry. My truck prob. has more wire than it should but not sure. You can see pic of mine in E-maxx in the sand

I also noticed that you are refering to schulze instead of BK?

I thought that is what the extra capacitors are for on the 9918. This allows for slighty longer wires. I know on the schulze controllers that's what they do for Emaxx controllers is add more capacitors so the wires can be longer. Let's face it on an Emaxx 4 inches of wire is near impossible.

The wire length is mostly to reduce glitching but if your wires are too long you can damage the controller. It is about the resistance, use 12 gauge wire if you can also, this helps lower the resistance.

Copper battery bars also have the lowest resistance even though they get ugly.

Basically, if you keep the wires as short as you can and keep the solder joints clean, you will not have any problems. The BK controllers are less susceptible to these problems. Obviously, it makes good sense to stay as close as you can within these guidelines, but I doubt you will have any trouble.

I learned something today...yay...lol

thanks guys
