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.<o:p></o:p></span></div></div><div id="yui_3_16_0_1_1424639803759_3163"><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; background-color: white; "><span style="font-size: 9pt; font-family: helveticaneue; "> </span></div></div><div id="yui_3_16_0_1_1424639803759_3164"><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; background-color: white; "><span style="font-size: 9pt; font-family: helveticaneue; ">-Ken<o:p></o:p></span></div></div><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; background-color: white; "><span style="font-size: 9pt; font-family: helveticaneue; "> </span></div><div id="yui_3_16_0_1_1424639803759_2679"><div id="yui_3_16_0_1_1424639803759_2678"><div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif; background-color: white; "><span style="font-family: helveticaneue; "> </span></div></div></div></div></div>_______________________________________________<br>NSRCA-discussion mailing list<br><a href="mailto:NSRCA-discussion@lists.nsrca.org">NSRCA-discussion@lists.nsrca.org</a><br>http://lists.nsrca.org/mailman/listinfo/nsrca-discussion</div></blockquote></div><br></div></body></html>
