00:00Okay, so if you're building a dummy load for testing power supplies, battery packs, or amp
00:04builds, cement resistors are the cheapest way to dump heat without melting your bench and I just
00:09went through the listings and found the 5 best deals out there. Some of these are under 3 bucks
00:14for a 10-pack, so stick around, because number 5 has the best rating of the whole bunch.
00:19First up, the one I'd tell almost anyone to start with, 10 pieces of 5-watt cement resistors,
00:245% tolerance, and the value range goes from 0.1 ohm all the way to 100 ohm, so you
00:30get the low
00:30ohm stuff you need for current sensing and the higher values for bleeding caps. It's $2.86 for
00:36the 10-pack, it's got almost 4,900 sales and a 4.8 rating, and honestly at that price you
00:42can
00:42afford to fry one and not care. If you want more headroom, step up to the 10-watt set, same
00:4710 pieces,
00:48same 5% tolerance, but the range stretches from 0.1 ohm right up to 10k, so you can build
00:54a proper
00:54series parallel load bank and actually pull some amps. That's $3.78, it's moved over 4,700 units,
01:02and it's rated 4.8 as well. Double the wattage for about a dollar more is a no-brainer if
01:08your
01:08project runs hot. Now for the heavy hitter, this is a single 50-watt ceramic resistor,
01:14and the value range runs from 0.1 ohm to 1k, so you can pick a 4, 8, or 10
01:19ohm and pull serious
01:20current for a short burst without it smoking on you. It's $2.91 per piece, it's sold about 4,400
01:26times, and the rating sits at 4.2, a little lower, and that's mostly because a single 50-watt needs
01:32real heat sinking and airflow, so mod it properly and it'll do exactly what you ask.
01:37Number 4 is the 5-pack of 10-watt resistors, same 0.1 ohm to 10k spread, same 5%
01:43tolerance,
01:43but only 5 pieces instead of 10. At $4.10 it's actually the weakest value per resistor on this
01:50list, so I'm including it for one reason, if you only need a couple of specific values and you'd
01:55rather not have a drawer full of spares, this lets you pick exactly what you want. 4,000 sales and
02:01a
02:014.7 rating, so people clearly aren't unhappy with it. And my pick for the top spot, 10 pieces of
02:085-watt,
02:08and this is the highest rated set here at 4.9 stars. The values are all in the low ohm
02:14range,
02:140.47, 0.5, 0.6, 4, 4.3, 4.7, 5, 5.1, plus 43, 47, 50, 51, 470
02:25and 510 ohm, which is basically a
02:27shunt and load bank starter kit in one bag. It's $2.96, it's sold about 3,900 times, and that
02:354.9 tells
02:36you the tolerance is actually close to what's printed on them. So those are the 5, links to
02:41every one of them are in the description below, and I'd grab the 5-watt 10-packs first and add
02:45a
02:4550-water for the big jobs. If this saved you some scrolling, hit that like button and subscribe,
02:51because I'm doing this every week. Thanks for watching, and happy building!
