Danny, if you see this- Are there any plans to go to non-internal wiring and the more common method of balancing (like TP, Orion, Intellect, etc)?

Here is my take on inboard connectors versus outboard wires and connectors.
To use inboard connectors we must use a circuit board to solder the female tubes. This means extra resistance as there will be more solder points. Connectors can get dirty and worn out so using inboard tubes means you can't replace them from time to time to keep the resistance as low as possible. The possibilty of reverse polarity is possible. So these are the negative things about inboard connectors. The positive thing is that wires can be changed and there is no external balance connector. It also looks cleaner/nicer but I don't think this is an advantage.
Outboard wires and connectors offers the racer to change his connectors to keep resistance at a minimum when needed. Reverse polarity is not possible when using a Deans or Traxxas style connector. If a racer wants the lowest possible resistance he can hardwire to the packs wires.
Our goal at SMC is to offer the best possible packs as far as performance so it really makes no sense for use to use the best possible cells and connect them in a way that will increase the IR.
We do plan on releasing EFRA/BRCA packs that will have inboard tubes as the Europeans have been using Bullet style connectors for years so Deans or Traxxas connectors will not go to well in the part of thr world.

Have you tested Trakpower power against your cells? If so, how do they compare?

There is more resistance when using inboard connectors as the circuit board adds solder points. I will try to get the difference in resistance soon as we do have circuit boards for our EFRA packs so I can try and measure the difference.
I really don't like to compare our packs to our competitors packs. The best thing to do is to try one of our packs and come to your own conclusions.

if the packs are as good as you say they are you should have nothing to worry about...I for one run cheap 5000s from truerc.com its hard to beat $75 for a good lipo...

Isn't the SMC 4900mah saddle pack really popular for the AE B44? I read a few posts back that you didn't have any packs that fir the AE cars??....maybe i read that wrong? If those 4900 saddles fit a B44....i'll be looking into getting a couple packs.

mabey solder posts will be the next big thing in lipo...

Still, I bet when you test someone else's pack and it falls far short it takes a herculean effort to keep from screaming it to the world.

Danny,
thanks for considering!
The dimensions with the pads in place are as follows:
143X48X33 mm. I could remove the pads and it would add about 2 mm but its minimal. Take your time and see what you could make, and if its even economically feasable for you to make a custome pack, you have to make money too. But I bet you would sell a bunch to the AE guys.
thanks again,
Trout

My SMC inventory is as follows:
2 x 2S 28C 7.4v 5000mAh
2 x 2S 24C 7.4v 5200mAh
My understanding is that the 28C uses higher quality cells. Danny, my 28C's have handwritten output results on the packaging, is that something you're doing?
I use the 28C's for Slash racing, yes, overkill, but the only electric racing I do is Slash and 2WD truck (Team AE T4). The weight of the 28C makes it perfect for the Slash and it allows that 12t to draw all the power it could ever dream of.
The 24C for the T4 is awesome, perfect weight, and when mated a Mamba Max and 5700kV there is more power than anyone could ever handle.
I would probably buy the 24C 5200's from now on, they're almost half the price of the 28c and for my applications they're still more than enough battery.
Keep up the good work SMC, you batteries really do deliver.
