No batteries come with the kits or RTR trucks. But the 80amp ESC has a 4s limit and its pre-wired for 2- 2s batts. At $320, the turn key kit is a great value considering all of the hardware that comes with the 80amp ESC and 2000kv motor and both come with cooling fans!! <div>
</div><div>I actually converted my Nemesis with this kit and I have to say, it's a scream!! Plenty of power!! In fact, I might say scary fast!!</div><div>
</div><div> I used 2 Gravity Brand 2s 65c 5000mAh for lots of discharge power and plenty of run time!</div><div>
