I am thinking about getting a lipo or two tomorrow for my Slash 4x4. I am leaning towards 3s butdo Ineed to upgrade anything on it so it can handle the extra power? How much difference in speed is there between 2s and 3s? I know that there are probably a million posts on lipos, but none that I can find seem to answer my questions.

If the gearing or nothing is changed on the vehicle then we have 50% more voltage and the power produced is more than 50% increase since the current goes up as well. The actual speed difference is something less than 50%.

sorry can't help with upgrades.

When you compare 3s to 2s 3s is going to be a lot faster. A VXL esc is borderline on 3s lipo. Meaning that it's very easy to fry your esc. 3s is also pretty crazy and hard to controle. I would go 2s if you want to actually controle your slash and not worry about frying your esc.</p>

There is going to be a significant difference between 2s and 3s. The 2s will make your truck scream, it is only 7.4 volts, but it will probably go much faster than if you used a 7 cell NiMH (8.4v), don't know whythat is but from what I've seen it's true. For the traxxas electronics I would go with the 2s.

Nothing to upgrade, but do this: keep the stock gearing. Traxxas has a larger tooth pinion gear for higher speed, but this puts a lot of load on the speed control and tends to burn it out. Stick with the stock gearing, don't over gear, you'll be fine.

Exactally, 2s is still really fast!</p>

Thanks, I've been into RC for awhile but I have never really thought of going lipo. Will I have to worry at all about frying my esc with a 2s?  Also I planned on keeping the stock gearing. I got the larger tooth pinion in the box with the Slash but I never planned on using it.</p>
