The controller can handle the cells with the proper motor selection. These little cells provide quite impressive power (almost as punchy as the larger 3300 or 3700 cells) and they are actually more energy dense than the larger cells. 50 mph could be achieved with 20 cells and you could still get a decent runtime. Of course, it depends on how you drive and where you drive as well. 50mph still takes a bit of energy in an e-maxx. I recently built a tuck for a customer using 20 cells and an xl2000 motor. Even dialing out half of the available power, the truck was capable of rolling wheelies at high speed simply by pulling then trigger! I didn't drain the batts(just tested them and sent the truck out), but the customer wrote me an e-mail praising the performance AND the runtime. He had run it over 10 minutes and hadn't dumped the packs yet. His truck is geared to reach high 30s to low 40mph(plenty fast for these trucks). More speed = less runtime, but the potential is there.
