If that's true Deans NEEDS to do some sort of genuine identifier and a mold change. People buy the clones because they are cheap AND they have better grip to use.
The actual Deans say they are Deans when you buy them. Clones will say "T-plug" or "Deans style/compatible." People should know when they are buying clones.
Don’t forget the solder job can also make a difference. You could have best connectors but if solder job is not good the connection is also not going to be good.
Definitely impressive. however they could most definitely use to do some kind of update... something that doesn't suck complete ass to solder! and I completely agree with them putting their actual brand on them as an identifier! Thanks for sharing!
I’ve been saying for years that genuine deans is the way, it’s small, it’s reliable, and easy to solder. Don’t need to stuff two massive EC5’s for a 2x 3s setup. Adam Drake has been using deans connectors in his racing e-buggy, and the rigours of racing can draw some serious current.
I try to make this point every time the subject of Dean's connectors comes up. So fed up hearing people go on about how 'crappy' Dean's connectors are. These were the original 'zero loss' connectors and were widely used in racing circles - completely transformed the industry and eliminated the need to solder motors and batteries for maximum performance. They're not perfect and I wish Dean's would redesign the connector to make them easier to solder and plug/unplug. Not to mention, make them easier to identify. I'm going to refer to this video every time someone brings up this topic! Thanks! 👍
Doesn’t matter for the majority of us. But if you’re really that worried about weight and efficiency then wouldn’t bullet connectors straight from the esc to the battery be better anyway?
I’ve been coaxed by a few shops near me to consider switching from Deans to XT-60. But the thing is… my original 2S LiPo was a Deans connection and I’d never had any issues and to this day, I have used nothing else. That battery I had? It was a GensAce “Vintage Tamiya” pack and the Deans connector was genuine as that battery was also sold through Kyosho USA. My Common Sense LiPo pack used a clone as the connector never seemed to fit properly. You can tell the difference.
If I have never learned anything on your channel this one was worth it all. I like Deans plugs. When started in RC there was Deans and Tamiya for the most part. Some type of Bullet plugs i am thinking but never saw them used. After about 10 years i return to a mostly electrified hobby. People talking trash about the 2 number one products. Deans connectors and Castle creations. Ita good to hear they are still worthy. 😂 Deans are easier to me anyway. And yes i have learned alot from your channel.😅
That was an interesting demo - thanks for sharing it with everyone! I have always used genuine WS Deans Ultra Plugs and WS Deans 'Wet Noodle" 12 gauge wiring on all of my R/C vehicles - no exceptions. I'm so old that back in the day nobody that I knew called them "T plugs" like now and they were always called by their trademarked official name "Ultra Plug." There also were no knockoffs of them either and WS Deans was the only company that made them, hence they were not exactly what I'd call "cheap" back then. Even though they were a little pricey, they were always money well spent in my opinion. The demo would have been even more helpful if it included all of the plugs that are commonly used today on R/C vehicles. As others have noted for example, no Traxxas connectors were shown.
Great video! I wonder how many of my connectors are clones... I switched to EC3 and EC5 to get away from the T plugs (Deans) because like you, I thought they were just bad.
You always know when you got a fake deans they just don't always even make contact well and gotta bend the spring contacts to engage better. Deans on deans is 100% connection every time and the plugs don't melt at all when you solder em up
Deans connectors have always been the goat since lipos and brushless systems were first introduced into the RC world. I have never understood the hate and dislike towards Deans. They have always been the best and still are! All my Lipos have always ran deans!
@@james654100 That's cool, don't gotta be a dick about it. Plus I don't even care about the Xmaxx I would never buy one. I'll stick with my Nitro Monster Trucks all day long. But 1/10 scale brushless stuff is an easy choice for me. Ive never had a Deans connector fail on me so why change what works.
You will understand the hate real quick once you connect 6s+ on a big car on a warm day and you melt them. Having to separate them and solder new ones on is NOT fun. Also it's almost impossible to know when you have original connectors. So unless you're willing to do research and resolder every single connector you have to original Deans, you will struggle. All this when you can just get a bag of EC5s/XT90 for like 5 bucks.
I’m so happy to see this… my Vorza s truggy only needs deans connectors..!! Stock.. have you got one yet bro!!? You need to. Would be nice to see you drive a Vorza 😎
Better test from the Deans guy would have been just checking resistance across a pair of connectors and then looking at the average across multiple pairs...gonna do this with my plugs now.
I don't know... maybe if they (Deans) were to redesign them, more substance to grab ahold of, I'd start using them again. Anderson Powerpole for the win! Just kidding... sort of.
Great video! Deans need to do something in marketing to ensure that us buyers know that they are original. There are thousands of knock offs out there and it is impossible to tell the difference. I guess the only option would be to purchase at a reputable dealer that doesn't sell knock offs and not an online giant that will sell anything. I've heard that deans aren't good for anything over 2S and why I haven't changed back to them due to heat. I will give them another try and ensure I only buy the originals. I agree MIP are the best!!! Thanks!
If you buy them as sold by WS Deans, you’re getting genuine. BTW, the “white” plugs are higher current. I had one on my Hobbywing 10BL60 Sensored. Wish I had them on my XD10 too.
There is a guy at my local hobby shop who has been in this hobby longer than most of us have been alive, and i hear him say all the time, Deans plugs are really good!!!! I guess he is right!!!
@@jerryvolpini7987 I can't imagine anything over 2s would be worth it I know this test shows they are good but what company do you know that demonstrates how crappy their products are they left out a lot of info I've seen deans and not knock off melt with 3s plugged into them but your in titled to your belief put a set of them on a 8s TRAXXAS or ARRMA heck a 6s car and see how hot they get and how fast especially using a powerful lipo something 6000mah 120c or better
My biggest issue with the Deans connector is that the design lets a lot of dirt into the plugs. This causes resistance to go up and makes the plugs fail. I have had so many fail or melt together because of this. Now....I'm sure the connectors I used were not this brand so I'm curious if they would have the same issue with the dirt. Interesting video!
Let’s start with: i didn’t even know there was a voltage drop in the first place 🥴 very interesting. Now i want to know Traxxas voltage drop cause i only use Traxxas bc.. well.. it’s there so
Not questioning the quality of deans connectors, but I do question the voltage drop test, you're not telling us the amount of voltage just amps and I would love to see the inside of those connectors with the higher voltage drop, there is something there causing very high resistance. Saying your connectors are better which they probably are but not showing us why doesn't make your connector better.
Deans Ultra plugs have a stated current limit of 90A continuous, with a peak of 150A (1 min burst). A 20C 50000mAh battery is 100A continuous (30C=150A at 5000mAh). They may be more efficient, but they can't handle the load.
Not wrong but you’re using theoretical maximums and C ratings which we know also has a lot of marketing BS. 150C for 60 seconds is a lot of current for a long time. Even the speed runners aren’t max for that long. Connector resistance matters more IMHO but it’s more complicated for the average hobbyist.
Our 90A rating is with 5" of 10 Gauge wire. At high currents it is critical to keep the wire lengths as short as possible. For example at 100A in just a few minutes 10" of 10 gauge wire will reach 200° F. In just one minute at 100A the resistance of that 10" length of wire will increase by 10% If you are able to find the manufacturers spec sheet on for example the XT-90 the continuous amp rating is 45 amps (not 90). 90 Amps is the burst rating. Using 5" of 10 gauge the Ultra Plug can burst 200+ Amps for 5 seconds. Remember most "burst" situations are much shorter than 5 seconds. At a continuous 100A In one minute the resistance of the Ultra Plug will increase by 3.2% in the same test the XT-90 will increase by 8%. If your wiring is getting warm to the touch increasing the wire gauge and decreasing the length will eliminate the power lost to heat.
If we use your formula (flawed) then it means none of the other connectors can handle the load either. The problem is that people go on about what great connectors the XT60s and 90s are and that the Dean's are crap and can't handle the same load. While the 'design' of these connectors might be an advantage, any claims about Dean's being inferior are just bullshit.
I used Deans for years, and I know the knock-offs suck. (so do the bargain xt-60's) But sorry, they still fail. Along with Traxxas connectors. Blade connectors collect dirt, which eventually degrades the connection and weakens anyway. Bullet based connectors may have some more resistance, but for most applications, do just fine. Most racing setups I've seen are either direct connection (with bullet connectors) or for speed run guys with high amperage draw (with multiple ESC's) Not really convinced Dean's would handle the high amperage draw (?) Not sure what the point of this video is, except as a big "so what" Mostly to sell more Deans...
Except the ones that come with ESCs or RTRs are not ultra plugs and WILL melt. The ones on my Savage XL did. Same with the ones coming with batteries. Also it's almost impossible to find ultra plugs in Europe, especially for a reasonable price. All the changes in branding and colouring are not helping either. It's much easier to just get a bag of EC/XT etc. connectors and get it over with. Even the fake EC5/XT90s won't melt so you don't have to worry about find the originals and resoldering every single ESC and battery you get.
I mean, Dean's is fine for crawling but I wouldn't use it for much else. Besides that, did he mention and show that he's using genuine IC and XT connectors? I didn't hear him say those connectors were genuine.
I’ve been saying this for years. I used to work at a mega size hobby shop and we ohm’d out several batteries with different connectors…several types of batteries, with several types of connectors, and the Deans branded plug had the lowest resistance every single time. They are far superior. The knockoffs just give them a really bad name. I’ve never melted a real Deans plug, even with putting crazy voltage through them.
I've melted 4 of them just on casual runs with my Savage XL on warm days. Was forced to replace them on the Savage and on my batteries. Absolute nightmare to deal with.
With using the right wire, and right solder, I ran the Deans Ultra Plug in a 8s purpose built speed run car with no issues. It’s not always the connector that causes failure. I’d say 99% of the time it’s the wire or solder causing the problem. I’d running high voltage, use silver solder and silver core wire with proper shielding, and in a large enough gauge. If you’re running enough to get your wires themselves over 200°F, then it’s probably time for direct solder and that would have to be something crazy. That being said, I’m not a Deans pusher either. I myself run deans on most cars my kids will drive, but on my race cars I run 5mm bullets.
If you are able to find the manufacturers spec sheet for the XT-90 the continuous amp rating is 45 amps (not 90). 90 Amps is the burst rating. At a continuous 100A In one minute the resistance of the Ultra Plug will increase by 3.2% in the same test the XT-90 will increase by 8%.
Surprise, the Deans guy says Deans are best. yeah, take that with a grain of salt. And none of that addresses the inherent safety issue of deans where they expose both contacts if they arent fully seated.
I think they are the only ones that are comparable, though having talked to Traxxas reps when they first introduced them, they were claiming that they had even less resistance. That said, ther than my Losi crawlers that had EC3 plugs, I’ve only run authentic Deans and Traxxas plugs on my stuff.
It's not about low voltage or even low amps, try that same test with 50+ volts and 600+ amps. And yes those that are speed running see 750+ amps running 8s-12s. Watched a vid showing the Perfect Pass QS8 connectors that they put 1000 amps through, the solder and wires failed (melted) but not the connector.
All this is true but its a bit hyped the dmm is in Mv thats millivolts theres 1000 millivolts in 1 volt so take a 3s lipo full charged at 12.6 volts even the worsed offender here at 12.5 mllivolt loss that battery would be 12.5875 volts lol.. the difference in the xt60 to the deans 12.5957... and 12.5987... its so small its almost silly compare just smaller number equal better argument ... the other test is spreading a current over all three of them and number is not a reflection of how many amps each connecter can take but the resistance electricity takes the path of least resistance in this case with those three paticular connectors the deans was the path of least resistance thats why the most amps was going there it doesnt mean more will flow to that connector over another if its the only one in the circut nessasarly .. but more resistance equals heat so the deans should run cooler ... but it doesnt mean it will allow more power to go through....
@@toolbaggersi run everything from 2s to 8s xt60s xt90s and even some deans i used 3s as an example it is true i have never melted a connector buts thats more to do with good solder joints and selecting the propper connector for the load that it has to carry
In the past they did. Now they are using clones. The Ultra Plug is now molded in a high temp BLACK resin (for a while it was White). The red color has been discontinued. We do not recommend using a mix of genuine Deans® and clones. The clones have sharp edges which damage the surface finish of our contacts.
@@RobinDeans I wondered about the red, I worked for a hobby shop when the clones started to appear. The first thing I noticed was a big difference in not just the shade of red but in the metal used. Everything just seemed to be a lot lower quality materials compared to yours.
$90 value for a $7 t-shirt.. $10 bag and $4.50 tool? No country on earth did it cost half that much in materials or cheap human/robot manufacturing labor to produce 😂 make it make sense mark...
I don’t care how “ good “ deans are ,that spring on the connector is going to fail at the worst possible time. I’ve hated deans for that reason since the 80’s and always will
maybe 2s would be ok idk im not sold and until someone other then them can prove this i wont be interested. theirs tons of ways to make others look bad and yourself look good if that makes since
I used to run Deans (not clones) and had a lot of issues with heat, melted connectors, battery failures etc. Switched to XT60 and XT90s and the problems went away. If you put on board telemetry in an e-buggy, or basher that showed real time amp loads, voltage drop etc. Deans would not win in the real world.
Obviously the first connection in line will have the least resistance and most current flow. These tests show absolutely nothing except people don't understand what they are looking at.
Non independent testing isn't reliable and a few mV as shown in this testing will make zero difference to most. All connector resistances shown tested here are next to measurable zero by the average consumer handheld meter. The way this guy says "wow" over a 4mV difference is cringe.
This is a pretty misleading video. I'll take myself as an example. I'm average in my soldering skills. Those resistances shown are not the resistances i will achieve. Indeed, those aren't the resistances most people will achieve. While bullet connectors do have a higher resistance, they also do have a CONSISTENT resistance. Deans don't. But what kills Deans connectors for me personally is just that they're so moronically designed. Yes, you save weight by having a tiny connector like that. You know what you're also doing? Forcing people to disconnect their batteries by pulling on the battery lead. Or, more specifically: by pulling on a round battery lead that soldered to a flat contact on a single side. You want me to buy Deans? Design a halfway decent housing. It's not rocket science. In fact, it's so stupidly obvious and easy that i can't even fathom why that hasn't happened a decade ago. Add a notch on both sides, or a border. SOMETHING to grab on. You will not get it apart by pulling on the housings, guaranteed, so you'll end up disconnecting it by pulling on the battery leads. Some people are fine with that, i personally cringe every time i have to. In essence: if you can solder well, Deans are a good alternative to XT90/EC5/IC5. If you're mediocre, you have a worse connector than the other two "big ones" in every single aspect. No better resistance, no better amp rating, a worse housing, with the added potential of pulling your battery lead off the contact every time you disconnect it (again: round lead to a flat contact plate - better make 1000% sure you don't have a cold solder joint, there's a reason why Deans are the only company to give out a warning to not solder their connector below a certain temperature - something that btw is much less likely in a bullet style connector, where the round lead attaches to the connector on all sides inside the round housing), and of course the infamous sparking. But i'd be fine with just a better housing. It's easy. There's no reason not to do it, any other connector can do it. Except maybe IC5, they're a bit awful for that too, but that might be my sausage fingers. But XT90, XT60 and QS8 connectors are all easily "disconnectable" at the housing, without pulling at the leads.
Interesting. Thanks for the knowledge.
If that's true Deans NEEDS to do some sort of genuine identifier and a mold change. People buy the clones because they are cheap AND they have better grip to use.
The actual Deans say they are Deans when you buy them. Clones will say "T-plug" or "Deans style/compatible." People should know when they are buying clones.
Agree. They need to add their name on the connector or something, so we know it's genuine.
If you bought them then you'll know if they're genuine or not. Plus they are the only ones (so far) that are black or white.
I use Deans battery plus since the 80s! Absolutely great stuff.
I've been trying to tell ppl for years that the real Deans were not shitty like the fake ones. This finally proves what I've been saying
I'm a Deans fanboy and always have been. I just need to make sure I buy the real Deans plugs from now on!
Don’t forget the solder job can also make a difference. You could have best connectors but if solder job is not good the connection is also not going to be good.
True true .
and thats why this test needs to be done by anyone other then the company themselves of course they are not going to tell you they have the worst

Xt60 has wire cap so no need for heatshrink. Im laazy lol.
Except the ones that come with ESCs or RTRs are not ultra plugs and WILL melt. The ones on my Savage XL did.
Same with the ones coming with batteries. Also it's almost impossible to find ultra plugs in Europe, especially for a reasonable price.
All the changes in branding and colouring are not helping either. It's much easier to just get a bag of EC/XT etc. connectors and get it over with.
Even the fake EC5/XT90s won't melt so you don't have to worry about find the originals and resoldering every single ESC and battery you get.
I was reading about this bout a month ago and I didn't wanna start shit with nobody. Now. I will 😅
I mean, Dean's is fine for crawling but I wouldn't use it for much else. Besides that, did he mention and show that he's using genuine IC and XT connectors? I didn't hear him say those connectors were genuine.
I’ve been saying this for years. I used to work at a mega size hobby shop and we ohm’d out several batteries with different connectors…several types of batteries, with several types of connectors, and the Deans branded plug had the lowest resistance every single time. They are far superior. The knockoffs just give them a really bad name. I’ve never melted a real Deans plug, even with putting crazy voltage through them.
Try putting crazy current or really high voltage where you need to ue a spark arrestor
@toolbaggers
I use Dean's on my 8s brushless converted HPI 5B and my Traxxas XRT--- Never had a problem with them🤷♂️🤷♂️
I've melted 4 of them just on casual runs with my Savage XL on warm days. Was forced to replace them on the Savage and on my batteries. Absolute nightmare to deal with.
With using the right wire, and right solder, I ran the Deans Ultra Plug in a 8s purpose built speed run car with no issues. It’s not always the connector that causes failure. I’d say 99% of the time it’s the wire or solder causing the problem. I’d running high voltage, use silver solder and silver core wire with proper shielding, and in a large enough gauge. If you’re running enough to get your wires themselves over 200°F, then it’s probably time for direct solder and that would have to be something crazy. That being said, I’m not a Deans pusher either. I myself run deans on most cars my kids will drive, but on my race cars I run 5mm bullets.
eliminate the plug and just do 5mm bullet connector straight to the battery.
They just suck to solder.
$600 a year for a subscription service is insane.
You'd still need an adapter plug in order to charge your lipos correct? Or do you have to buy a charger specific for Deans plugs
You can do either
Tell them to honor there damn lifetime warranty since you have contact with them. Most of us can’t even connect to them
Very interesting. I don't think we can get them in the UK.
Wonder how many amps they can run efficiently?
Does deans make a connector that can take current as a xt90 with minimal voltage drop?
If you are able to find the manufacturers spec sheet for the XT-90 the continuous amp rating is 45 amps (not 90). 90 Amps is the burst rating. At a continuous 100A In one minute the resistance of the Ultra Plug will increase by 3.2% in the same test the XT-90 will increase by 8%.
@@RobinDeans Cool. Works for me. Definitely not low quality metals. That test board and presentation was great.
Which RCBoxClub level is this in
Surprise, the Deans guy says Deans are best.
yeah, take that with a grain of salt.
And none of that addresses the inherent safety issue of deans where they expose both contacts if they arent fully seated.
Are deans better? Better than qs8? I think we need a 3rd party tester.
The best connector is no connector at all lol
I'll take Amass plugs
I thought this was common knowledge
Why does he not have Traxxas connectors on his board ?
I think they are the only ones that are comparable, though having talked to Traxxas reps when they first introduced them, they were claiming that they had even less resistance. That said, ther than my Losi crawlers that had EC3 plugs, I’ve only run authentic Deans and Traxxas plugs on my stuff.
The only thing better than a Deans Connector is direct soldering.
WOW !!!!!!! THAT WAS MIND BLOWING… 🤙🤙🤙🤙🤙🤙
It's not about low voltage or even low amps, try that same test with 50+ volts and 600+ amps. And yes those that are speed running see 750+ amps running 8s-12s. Watched a vid showing the Perfect Pass QS8 connectors that they put 1000 amps through, the solder and wires failed (melted) but not the connector.
Why didn't he do the QS8 connector?????? We are not too worried about weight speed running. But he should have done that test.
The QS8 is a whole different animal. A comparison is pointless.
I think you owe them to at least put Deans in the title. Like "deans best connector" or whatever. WIll help you get more views too..
All this is true but its a bit hyped the dmm is in Mv thats millivolts theres 1000 millivolts in 1 volt so take a 3s lipo full charged at 12.6 volts even the worsed offender here at 12.5 mllivolt loss that battery would be 12.5875 volts lol.. the difference in the xt60 to the deans 12.5957... and 12.5987... its so small its almost silly compare just smaller number equal better argument ... the other test is spreading a current over all three of them and number is not a reflection of how many amps each connecter can take but the resistance electricity takes the path of least resistance in this case with those three paticular connectors the deans was the path of least resistance thats why the most amps was going there it doesnt mean more will flow to that connector over another if its the only one in the circut nessasarly .. but more resistance equals heat so the deans should run cooler ... but it doesnt mean it will allow more power to go through....
You sound like a low amp man that has never melted connectors (in use) before!
@@toolbaggersi run everything from 2s to 8s xt60s xt90s and even some deans i used 3s as an example it is true i have never melted a connector buts thats more to do with good solder joints and selecting the propper connector for the load that it has to carry
But it proves the clones have contributed to the bad image of Dean's and that Deans is still a top level connector.
All I run are deans
That, and deans connectors are lighter....every gram matters
So do Associated use offical deans.
And what about on all the different batteries.
How can you tell.
In the past they did. Now they are using clones. The Ultra Plug is now molded in a high temp BLACK resin (for a while it was White). The red color has been discontinued. We do not recommend using a mix of genuine Deans® and clones. The clones have sharp edges which damage the surface finish of our contacts.
@@RobinDeans
I wondered about the red, I worked for a hobby shop when the clones started to appear. The first thing I noticed was a big difference in not just the shade of red but in the metal used. Everything just seemed to be a lot lower quality materials compared to yours.
Literally everyone just re learning what I've been saying for years but noooo they all know better 😒
I'm not saying that Deans connectors are good or bad, but I would much rather see a proper test done by a 3rd party technician.
$90 value for a $7 t-shirt.. $10 bag and $4.50 tool? No country on earth did it cost half that much in materials or cheap human/robot manufacturing labor to produce 😂 make it make sense mark...
I don’t care how “ good “ deans are ,that spring on the connector is going to fail at the worst possible time. I’ve hated deans for that reason since the 80’s and always will
32s ago
6mins ago
i dont by it sorry but id rather see it proven by someone other then them....
maybe 2s would be ok idk im not sold and until someone other then them can prove this i wont be interested. theirs tons of ways to make others look bad and yourself look good if that makes since
This might matter in another use than the RC hobby. 5-10mV drop over a connector is absolutely within acceptable tolerance for RC use.
Good job lumping all RC into one category. 2 amps and 200 amps require different connectors.
Thats a straw man argument if i ever heard one. Im sure he'd agree with your statement @@toolbaggers
Deans fall apart after like 20 uses..
and no good for 6s.
I used to run Deans (not clones) and had a lot of issues with heat, melted connectors, battery failures etc. Switched to XT60 and XT90s and the problems went away. If you put on board telemetry in an e-buggy, or basher that showed real time amp loads, voltage drop etc. Deans would not win in the real world.
Obviously the first connection in line will have the least resistance and most current flow. These tests show absolutely nothing except people don't understand what they are looking at.
Non independent testing isn't reliable and a few mV as shown in this testing will make zero difference to most. All connector resistances shown tested here are next to measurable zero by the average consumer handheld meter. The way this guy says "wow" over a 4mV difference is cringe.
This is a pretty misleading video. I'll take myself as an example. I'm average in my soldering skills. Those resistances shown are not the resistances i will achieve. Indeed, those aren't the resistances most people will achieve. While bullet connectors do have a higher resistance, they also do have a CONSISTENT resistance. Deans don't.
But what kills Deans connectors for me personally is just that they're so moronically designed. Yes, you save weight by having a tiny connector like that. You know what you're also doing? Forcing people to disconnect their batteries by pulling on the battery lead. Or, more specifically: by pulling on a round battery lead that soldered to a flat contact on a single side. You want me to buy Deans? Design a halfway decent housing. It's not rocket science. In fact, it's so stupidly obvious and easy that i can't even fathom why that hasn't happened a decade ago. Add a notch on both sides, or a border. SOMETHING to grab on. You will not get it apart by pulling on the housings, guaranteed, so you'll end up disconnecting it by pulling on the battery leads.
Some people are fine with that, i personally cringe every time i have to. In essence: if you can solder well, Deans are a good alternative to XT90/EC5/IC5. If you're mediocre, you have a worse connector than the other two "big ones" in every single aspect. No better resistance, no better amp rating, a worse housing, with the added potential of pulling your battery lead off the contact every time you disconnect it (again: round lead to a flat contact plate - better make 1000% sure you don't have a cold solder joint, there's a reason why Deans are the only company to give out a warning to not solder their connector below a certain temperature - something that btw is much less likely in a bullet style connector, where the round lead attaches to the connector on all sides inside the round housing), and of course the infamous sparking.
But i'd be fine with just a better housing. It's easy. There's no reason not to do it, any other connector can do it. Except maybe IC5, they're a bit awful for that too, but that might be my sausage fingers. But XT90, XT60 and QS8 connectors are all easily "disconnectable" at the housing, without pulling at the leads.
