berman 5315 Posted July 28, 2015 I am currently trying to fit some spotlights to a workmates rc. He is using a castle sv3 which I believe has a poor internal bec (4.8-5.0v). I plugged in a premade set of x4 LEDs which I think are 2x series (6.0v) The lights barely have a glow, if I plug in a 4.8v receiver pack they get quite a bit brighter but not as bright as my set does with a esc with a 6.0v internal bec. Bottom line is mate doesn't want to fork out $ for a castle bec just to power some lights, can I run one of these hobbywing ubecs? What are my other options? http://www.ebay.com/itm/3A-UBEC-5V-6V-Full-Shielding-Antijamming-Switching-Regulator-New-FE-/231466543686?hash=item35e47b2a46 Cheers.

Backlash 481 Posted July 28, 2015 Why don't you just add in some resistors, and run them directly off the 7.2V battery?? It has to be a cheaper alternative to buying a separate UBEC.. Here is a LED resistor calculator.. http://ledcalc.com/ Personally, I run a separate resistor to each LED.. Share this post Link to post Share on other sites
berman 5315 Posted July 28, 2015 Yes of course *facepalm* didn't think of running resistors! Cheers bud. Share this post Link to post Share on other sites
