The caps on the front-end of the ESC can instantly draw a huge surge of current for a short time. The arming systems for that sized pack usually have a button with a resister in series. You hit the button for a few seconds and that lets the caps charge up slowly. Then you plug the full-current connector in.</div><div id="yui_3_16_0_1_1424639803759_3163"><br></div><div id="yui_3_16_0_1_1424639803759_3164" dir="ltr">-Ken<br></div><br><div id="yui_3_16_0_1_1424639803759_2679" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"><div id="yui_3_16_0_1_1424639803759_2678" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"><br> </div> </div> </div></body></html>
