Copper Lug Crimping for 2/0 Welding Cable for your Lead Acid Batteries. Manual Crimping of the heavy Cast Copper Lugs work just fine and give a superior crimp over the hydro crimpers you can…

A quick walk-through of my backup generator solution. The inverter is a 1500W unit from Harbor Freight @ 0. For cables, I started with 20′ of Walmart Everstart Maxx 4ga jumper cables,…

Nice vid, but I think it could do with some editing. A couple of comments
regarding the contents. 1) It’s NOT a hex-crimp, these are 6-sided whereas
the one you refer to as a hex-crimp is 4-sided. The sides aren’t even
parallell so it seems it just squeezed together in some weird manner. Would
be interesting if you compared to a genuine hex-crimp. continued below…

Your hydraulically crimped lug is a very poor one. The h-crimp has only
been done once. It should be done all round and all along the lug barrel to
form a proper hex x-section. The broken strands are well away from the
crimp and irrelevant. Lastly, the wire *was* clean until you put your
grubby mits all over them and not cleaning the lug inside will cause
heating and ultimately a spectacular failure of the joint at constant high
currants. Use a internal pipe cleaning wire brush. MW.

2) At 11:31 and a couple of seconds on it looks as if the hammer-crimp has
a crack in the tube – this opens up for corrosion inside the terminal. If
the hammer-crimp is used care should be taken NOT to cause cracks in the
connector tube. 3) As I have understood it, the fact that the strands are
alsmost fused together when using the hammer crimp actually reduces the
current carrying capability (ampacity) of the cable, this happens when too
much pressure is applied. continued below…

My guess is you could avoid 1) and 2) by using fewer blows or less power,
the problem is repeatability – when using a hammer crimp it is more or less
impossible to do identical crimps, this is where the (genuine) hex-crimp
shows it’s true colors.

You Gott it Di! A simple demo beats a lot of hot air on the EVDL. I’m gonna
try to weld my hammer crimper to a steel base plate in order to keep things
from bouncing around so much during the deed. btw, love the
ergonomically-enhanced hacksaw, but please lose the chimes next time!

Show and tell is far better than just telling. I like your idea of welding
the crimper to a large plate. I think a good anvil will be good. Welds may
not hold but you can sure give it a try. Next time the chimes will be gone.
I hope to do a better show later. One on a table top or anvil. So you like
my hacked hack saw! Works perfect 🙂 Pete 🙂

I’d be happy to give your terminal lugs a crack with the hammer and give
you my opinion. Send me your contact information and we can go from there.

Thanks for this, just what I was looking for!

Hello, congratulations for the movie, is really very nice, I am a
manufacturer of battery terminals, I would love if you tried mine, to give
me an opinion, if you like contact me.

I’d be happy to compare to a 6 sided vs a 4 sided hydraulically crimped
lug. I guarantee you the same results. I have had 6 sided ones pull out.
Once I get my hands on a 6 sided one I will do an update to this. The 4
sided one was however crimped pretty hard. But nothing like the manual
hammer crimp can produce. Again, the purpose was to show results, not be
politicly correct.

Martin, The exercise was to show the quality of the hammer crimp vs the
hydraulic crimp internally. If the hydraulically crimped end had been done
three times and in alternated properly the cut section would still look the
same. Next time I will wear gloves to keep the cable clean from grubby
mitts and I will recommend that the inside of the lug be cleaned. That was
not the point of this video. The photos tell the story and I need not say
any more about the subject. Pete 🙂

You use a setup similar to what I use for backup power, backfeeding into a
240V dryer plug! So long as the main breakers are off it works well.

Are you sure this backfeed practice is safe? When we had storm Atlas here
in the Black Hills last October, I had backup power with a Honda EU-2000i
generator (great sine wave) but fed only the essential devices (some
lights, computers, ham radio, furnace) through dedicated cords, completely
isolated from the home electrical system.

@rixmag Idle was normal in park, around 875 rpm.

Some of that junk is empty cardboard boxes but a lot is “stuff.” Computer
stuff, car stuff, house stuff…I don’t need all of it but it’s not all
trash.

Very clever setup, Kev. Did you have the car idling faster than normal to
account for the lower output at idle, compared to at speed?
