Yes, that would be much better. You need a larger surface area to dissipate the heat.
Great! Since I'm new at this I could really use some help calculating the Watt rating needed for this circuit (36v system). Been looking at power resistors as well (up to 50watt). Any problems using a...
Cool! Found an even smaller 51ohm resistor and soldered it as a bridge. Controller back to life! Not for to long though I suppose. I run a 36v battery on this bike. You think I could connect maybe 4x 200 ohm resistors in parallel to achieve 50 ohm and better heat dissipation?
Only one of the...
Hi all of you enthusiastic people! I am trying to repair an e-bike (hub motor, some Chinese no brand controller) and I got a new controller. The bike came to life but died again shortly thereafter. I opened up both the old and the new, identical controller and found a component that looks burnt...
