It's the Roboteq XDC2460, rated for 80A continuous duty per channel. But now I'm looking at Kelly I really like what I'm seeing there too, and Curtis seems to be similar. This will probably come down to a decision between a more advanced dual channel from Roboteq or a super simple single-channel controllers from the likes of Curtis/Kelly. In general if the simpler one can do the job, it's the one I would prefer even if it cost the same. </div><div><br clear="none"></div><div>Thanks guys for all the input!</div><div><br clear="none"></div><div>Alec</div></div><div><br clear="none"><div>On Tue, Apr 19, 2016 at 6:09 PM, Alan James via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank" rel="nofollow" shape="rect" ymailto="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>></span> wrote:<br clear="none"><blockquote style="margin: 0px 0px 0px 0.8ex; padding-left: 1ex; border-left-color: rgb(204, 204, 204); border-left-width: 1px; border-left-style: solid;"><div><div><div style="color: rgb(0, 0, 0); font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px; background-color: rgb(255, 255, 255);"><div><span>Hi Alec,</span></div><div dir="ltr"><span>that one says brushless?</span></div><div dir="ltr"><span>On the Kelly faq page for selecting controllers it suggests.....</span></div><span></span><h2 style="font: 17px/25px Oswald, sans-serif; margin: 1px 1px 3px; padding: 0px 0px 10px; color: rgb(64, 64, 64); text-transform: uppercase; text-indent: 0px; letter-spacing: normal; word-spacing: 0px; white-space: normal; font-size-adjust: none; font-stretch: normal; background-image: none;">HOW TO CHOOSE A SUITABLE CONTROLLER FOR THE MOTOR?</h2><div><div style="margin: 0px 0px 10px; padding: 0px;">Usually the performance will be optimized if the power of the controller is 2.0-3.0 times of the motor's.</div></div><div dir="ltr"> I guess that means if you have a 2000W motor you get a controller whose continual</div><div dir="ltr">amp rating X max voltage is at least 4000W.</div><div dir="ltr"> I have heard that it is better to aire on the safe side as some manufacturers over rate</div><div dir="ltr">their controllers.
