Where to buy 24 AWG terminal rings

[deeperblue]

Hi,

The BMS I bought uses 24 AWG balancing cables. The cables don't have terminal rings on them. Where can I find quality 24 AWG ring terminals for M6 stud? Searching on Amazon I can find some but first they seem to be very expensive ($9-$10 for 10 pieces), and second either there are no reviews or the reviews are poor.

Where can I find good quality 24 AWG ring terminals?

Thanks!

I like these. 100 seems like a lot but i find its a good amount since i have quite a few batteries.

Oops...

"22-18 AWG Non-Insulated 1/4" Stud Ring Terminal - Butted Seam (100/Pkg.)"

Not 24.

In my experience, 24AWG is too small for crimp connectors. You often get bad/loose connections.

The above could still work if you are handy with a soldering iron.

I found that they worked perfectly. There are dang few bulk options from my experience. I'm well into my second pack of these with no problems. One could always double over the strand if a tighter fit was desired.

Thanks. Guess I should go up to 22AWG rings and then use soldering.

Yeah, but were you using them with 24?

All the crimp tools I have show the smallest ga. wire to be used as 22.

I'll stick with solder on 24. I hate tracking down bad connections, esp. when they are my own fault.

Strip off twice the amount, fold the wire over, crimp.

I think some were even smaller! While they are surprisingly sturdy for their size, getting the barrel completely compressed was easy.
Giving them a good tug to make sure its solid always a good idea. Having 100 at the ready allow you to be pretty aggressive investing.

Just wondering if the conductivity differences between lead and copper might affect the thousandths of a volt measurements?

Yep

That was my solution

Bought mine off eBay.

Heat Shrink Electrical Wire Connectors 10-22AWG Ring Spade Crimp Terminals | eBay

Heat shrink insulated connectors will provide improved pullout strength and strain relief. The translucent heat shrink material allows for visual inspection of the connection, and has the wire gauge printed on it.

Came in a pouch, no complaints.

I used this and doubled over the wire.

I have learned that 16-22 insulated terminals are very unreliable. I use non insulated, brazed barrel, long neck terminals. The longer neck is so the nut will easily clear the barrel. I use the 2.5 position of an MC4 crimper and place the barrel so that it folds in at the brazed part not a dent like other crimpers. For 22 or 24 awg I definitely cut twice the normal length and fold then crimp. I then put a dab of solder just seal the end since the heat shrink doesn’t quite close up the end. This clear heat shrink is great because it works like the perfect soft strain relief and I can put a label in it.

That’s a lot more work than I’ve put in, lol, keep it up, that’s good stuff.

I bought off Aliexpress these for 22AWG. They worked decent for my BMS leads.

I double folded my leads and crimped with my ratcheting crimper. Seems good to me.

Now I'm debating whether or not to redo them - cutting them shorter so I don't have a nest of wires to wrangle with.

I'm on my second jar of these.

All it takes is a couple of session of a wild goose chase just to chase it down to a bad crimp to turn you OCD

So far I have 4 BMS, 3 8s and a single 4s running without issues (knock on wood).

I used a Kline crimper and the spot for insulated for insulated terminal. I used the two handed ostrich choke of death on the handles and lo and behold it wasn’t enough.
Probably crimped thousands of terminals but the little 16-22 insulated ones are simply EVIL.

Same Kline crimper (red handle) but she held

 

[littleharbor2]

Just out of curiosity I looked up Klein crimper and I found every variety of crimper known to man with Klein's name on them this is the one that I use and it works great.

 

[Skypower]

This is the one I have(#1005) and the cutting anvil has been moved away from the sharp side to close further to allow the crimping areas to squeeze tighter, but I still don’t trust it. You can see how much bigger the gap for insulated still is compared to others even after reducing it. The Kline is listed for 10-22 but I’d be reluctant to use it for anything other than blue and yellow connections. I thought it would have lots pressure because wit being close to the pivot but it doesn’t matter if it can’t close down enough. White background is stock photo(big gap)

Yup that same red handle.

Fold over JK balance leads and passed the tug test on the pink insulated 22awg lugs and most recently non insulated lugs provided by luyuan.
