I personally don't believe in them.

The power that is available from the batteries is not increased. It might work, in an ideal world. (where the current limit of the batteries is not the limit of the setup)

and they can't handle unlimited power either, right?

They are rated at 30C cont. and 60C burst, which would be 138 amps and 276 amps. I'll find out their capabilities soon enough, I guess.

Anyway, I just wired up my speed controller, and I want to make sure that it is ok. Since it will always be used with two packs, I wired up two dean's connectors to it. This will work, right?

That connector arrangment should work just be careful after you connect one pack your other male plug can arc on the chassis, not really a big deal in that brief moment until you connect the other pack.

I don't think that 2x the voltage means 1/2 the runtime. The runtime would be halved only if the current doubled. As long as the current draw remains the same, then a voltage increase will not decrease the runtime.

You have it wired good, butthe series lead seems short. i like to have mine a tad longer to leave room to spread apart a tad to get to the batts. But that's in a maxx.

It's just barely long enough. I didn't want it to have any slack, since it passes directly over the driveshaft.

Then you'll be fine! You may want to protect it in case the shaft breaks. i had a shaft break once and flapped around and wrecked my upper plate before....not good! don't even want to know what would happen if it cuts a wire!!!!!!!

I did my first test run today. I used the A123 packs without the turbos to get a baseline speed. Geared 46/16, the truck got up to 38 mph by my gps. That's almost exactly the 40 mph predicted by Brian's speed calculator, assuming 0.5 in. radius of tire ballooning. With the turbos on full boost, I should be around 60 mph. It looks like I'll have enough speed without the turbos for racing, though. I'll just use the turbos for bashing.

The truck is a mess of wires right now, but I'll post pictures when I get it cleaned up some.

Test it with turbos and see if it really runs 60 mph. I have doubts.

Yeah dude... test them things... I'd really like to see it for myself.... I don't have any confident on those things.... I beleive what gassdr sad.... "no free lunch" but try them on dude.. and Prove us all wrong.. :) great job on the conversion..

and make a vid too lol.. nice conversion btw

Hey cart, I'm reading about those batteries, and they're only capable of 69Amps continuous.... for the 2300mAh packs and the 4600mAh pack.. unless they have a major typo on their website... those battery looks pretty cool... especially the shape of them... and safety.. and charging rate... :)

No, all of the packs are capable for 30C cont. amps, so the 4600 would be double the 2300.

I weighed the truggy and got some pictures of it. I weighs 9.6 lb fully loaded. That's about 0.5 lb heavier than the nitro version. I'll try out the turbos this weekend to see how they do.

How is the lvc going to work for the turbos?

According to A123, a LVC isn't really necessary...
