Connectors and crimpers

I am considering the same purchase for the Andersons, MC4, and heat shrink connectors. Do you know what the B-F connectors are good for?

I also bought a cheap weather pack crimper I have yet to use.
I was going to say Blue Falcon, but I don't want to look bad in front of our peers, so I learned something all by myself.

Bootlace Ferrule
Crimp bootlace ferrules are metal tubes crimped (compressed for the purpose of joining) over a stranded wire to allow for a reliable connection with screw or spring clamps. Most crimp bootlace ferrules have a colour-coded insulation collar that protects the connection from contacts.

How do crimp bootlace ferrules work?
With crimp bootlace ferrules, you crimp the component's metal tube rather than the insulation, whereas with a standard terminal you do the opposite.
Once you have stripped your wire or cable, push it into the ferrule through the plastic collar so that the conductor insulation covers the entire collar and the stripped part is in the metal tube. You then use a crimping tool to crimp the metal tube to hold the wire or cable in place for a stable connection.

What are crimp bootlace ferrules used for?
Crimp bootlace ferrules are used to provide the high degree of contact reliability required by a wide range of applications, including control units, switching cabinets, function units and equipment with poke-in clamp or row clamp connectors. They are available in a variety of designs to suit different wire or cable sizes.

F-crimps are the AMP style for open-barrel, also known as B-crimps after the cross-section shape

That's similar to how most battery packs are made from those little cylindricals.

If you can afford the $10,000 welder, no problem.

Only $10,000? After careful consideration, I've decided that spending $1000 per incident to avoid crimping cable lugs is just outside my budget at this time. Sorry PB, but I'll have to make due with clumsy, outdated mechanical crimping for now.

My CMI crimper arrived. Out of curiosity, has anyone figured out the name brand equivalent? It's a very good looking tool, yet it lacks any markings past those used to indicate the correct gauge or connector to use. That kind of omission makes me wonder if it came off the same production line as an otherwise identical, more expensive tool.

I'm guessing the next significant step up in a crimper would be parallel movement of the jaws. I have a desire to own every KNIPEX product, so I checked out their crimpers. Though far outside my budget, their modular system seems to have deep die support, and their eCrimpers would be cool for production. They even have a kickin' theme song.

You missed calculating signifigant cost saving to eliminate terminals entirely.
Weld the conductors directly to wherever they need to be.
Hmmm ... interesting idea. Please post a video of someone you dislike doing that to a Group 31 FLA battery. Use a high frame rate to better capture the excitement.

Seen it done frequently on traction batteries. Its not exciting at all.
I figured there'd be enough risk of explosion that it wasn't done directly to a vented battery. What kind of application are you talking about?

My understanding is that Rod contracted with a known-good Taiwanese maker for a custom run to his design

Same with his Bed-It butyl tape, best quality out there, not available through branded channels.

That could be, but then I wonder why there isn't even a CMI stamp on it, or at least molded into the grips. Whatever that would cost doesn't seem like much, but maybe it would be. ?
