I’m assuming that’s because of the EMF back flow from the ESC into the batteries raises the voltage significantly when the brake engages, but maybe that’s only a problem when running 12s batteries?</div><div class=""><br class=""></div><div class="">Jerry<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jun 12, 2020, at 4:20 PM, davel322 <<a href="mailto:davel322@comcast.net" class="">davel322@comcast.net</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" class=""><div dir="auto" class=""><div dir="auto" class=""><br class=""></div><div dir="auto" class=""><a href="http://www.castlecreations.com/en/accessories-5/cc-bec-pro-010-0004-01" class="">http://www.castlecreations.com/en/accessories-5/cc-bec-pro-010-0004-01</a></div><div dir="auto" class=""><br class=""></div><div dir="auto" class="">Castle ProBec will do that easily.</div><div dir="auto" class=""><br class=""></div><div dir="auto" class=""><br class=""></div><div id="composer_signature" dir="auto" class=""><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" class=""><div style="font-size:85%;color:#575757" class="">Regards, </div><div style="font-size:85%;color:#575757" class=""><br class=""></div><div style="font-size:85%;color:#575757" class="">Dave</div><div style="font-size:85%;color:#575757" class=""><br class=""></div><div style="font-size:85%;color:#575757" class="">Sent from my Sprint Samsung Galaxy Note8.</div><div style="font-size:85%;color:#575757" class=""><br class=""></div><div style="font-size:85%;color:#575757" class="">Apologies in advance for any typos undoubtedly introduced by auto correct and / or talk to text. </div></div><div dir="auto" class=""><br class=""></div><div class=""><br class=""></div><div style="font-size: 100%;" dir="auto" class=""><!-- originalMessage --><div class="">-------- Original message --------</div><div class="">From: jerry--- via NSRCA-discussion <<a href="mailto:nsrca-discussion@lists.nsrca.org" class="">nsrca-discussion@lists.nsrca.org</a>> </div><div class="">Date: 6/12/20 18:41 (GMT-05:00) </div><div class="">To: NSRCA-list List <<a href="mailto:nsrca-discussion@lists.nsrca.org" class="">nsrca-discussion@lists.nsrca.org</a>> </div><div class="">Subject: [NSRCA-discussion] 10S UBEC Question </div><div class=""><br class=""></div></div>Does anyone know of a 10S UBEC that will output 8.2V and will handle HV (43.5V) packs?
