That is a surprising amount of current. It's been baffling to me why people have pushed the PH2.0 connector when we had a perfectly good connector. I'd love to see a PH2.0 vs Molex/Micro Losi. Excellent videos, very quantitative and helpful.
This series is great, thanks so much. The comparison with other connector types in a similar weight/current-capacity class is especially interesting. I would love to see videos on JST-RCY, JST-PH 2.0, as well as on balance connectors. I've been frustrated with the size of JST-RCY and didn't want to add the weight of XT30, so I've moved to using 2S balance connectors as the main battery lead connector on some of my lightweight 2S builds. I would assume that JST-RCY, JST-PH 2.0, and balance connectors perform similarly (maybe JST-RCY is more different?), but would be great to see empirical data! The balance connector test may also inform the "debate" on whether it matters to plug in the main discharge lead or balance connectors when parallel charging :-).
It seem like Molex 2mm connector is being phased out and generally replaced with JST PH 2.0. I'd love to see a review/comparison of the JST PH 2.0. Thanks
I have written that down on "the list"! I wouldn't expect it to perform better, but I'm definitely open to be surprised :) Might take us a while though, as the next 2 videos are already in the pipeline.
Does the PH 2.0 have more surface contact area? The plastic housing is designed more for anti-vibration. The LOSI connector probably better for batteries, since it can slide in & out easier.
Any chance you'll do jst-ph 2.0? I see statements that performance is better, but I haven't seen a test performed on them like you've done here with the molex 2mm
Yes! I am very much looking forward to doing that. I already have the connectors on my desk, but the laboratory/workshop we use for our tests and video recordings is on lockdown due to the pandemic :/ If they won't reopen by summer, I'll try improvise these tests with some lighter equipment. Fortunately the BT2.0 is so small, that I likely won't need the big 600A supply to push it to its limits :)
Yes! We have that on our short list, with just 2-3 things queued ahead of that. If we keep the new "one video every two weeks" schedule, we should have that reasonably soon.
You know what i'd like to see? Tests of just wire itself; the current each gauge of wire can handle continous and for 10 sec before desoldlering itself (test everything on xt90s so that it's just the wire not the connector overheating).
I hunted down the part numbers and terminals for LOSI connectors. I could not find any gold plated, copper-brass alloy terminals. I actually could only find one grade of terminals. This is unusual, since they usually have a long list of different plating, alloy, wire gauge. Who knows who is stamping the terminals, and what material they are using.
Well, since the metal contacts need to be crimped on the wire *before* being inserted into the plastic housing, you can't get this connector assembled but without the wire. Either full set, or get the pieces separately (octopart.com/51006-0200-molex-289446 and octopart.com/50012-8000-molex-945260)
Hobbyking has them: hobbyking.com/en_us/molex-2-0-2-pin-cable-male-connector-with-200mm-x-24awg-silicone-wire-5pcs.html. There also is a separate listing for 5x females.
We have that video almost done! Should post it next week! (Spoiler alert: It's a good connector, but not as great as the marketing material would suggest)
That's a tricky problem to debug. It could be faulty connector with bad contact, OR it could be something wrong with the drone - like an underperforming motor that takes a lot of extra power - with the hot connector only being a symptom of the extra power consumption. First check if any of the motors gets much hotter than the other ones after an attempted take-off. If that's the case, you might have to replace that prop or motor. If not, and it's only the connector getting hot, you can try replacing it. These connectors aren't too difficult to replace if you have a soldering iron, just get one that comes with a length of wire already crimped on the connector.
The banana you see is the reference "Banana for scale". It has a rating of one equivalent banana dose, denoted "B". This way we could do A-B testing with it and our Ampere meter. Banana plugs take 16A officially.
Ideally you'd use the dedicated Molex 63811-7800. You can get away with a generic 24AWG "universal" crimping tool, like the SN-01 shown, thought that requires a lot of patience and the results might be sloppy.
Please tell me the model number or part spec of that 2 mm connector. I have ordered them and they happened not to be thin but thick. Bottom line: I lost my money.
The part number is Molex 51006 (link to manufacturers website: www.molex.com/molex/products/part-detail/crimp_housings/0510060200) Although, this way you will get it as separate pieces that need to be crimped together. From RC stores you can try to look for it as "Losi connector" or "mini molex" but that's never a guarantee
Good lord thank you for making this. I just wasted an hour trying to find this thing at Digikey and Mouser.
Long live to people like you! thank you.

Your testing and video series on RC connectors are insightful and incredibly helpful. Kudos, and thank you!
Just found your channel! Absolutely fantastic content for our hobby!

I really like these video's keep it up
Very interesting! Subbed.

Loving your videos and style
What can you teach us about the MX plug found on the inductirx over the awesome Mcpx found from say Mylipo ?
Hi guys. Great video! Could you please elaborate on JST 1.2 and JST 2.0 connectors used on tiny whoop? Thanks a lot ;)
Huh, very interesting comparison with the JST.
Just found out this QUALITY channel yesterday, but looks like they aren't active anymore...
WHY 😭😭😭😭
Work was hard. But should be able to make something by spring. We’ll try for sure!
You need to do one of this for PH2.0 vs BT2.0
Can you guys PLEASE test the BT 2.0 Connector! Keep up the great content!!
Yes! I am very much looking forward to doing that. I already have the connectors on my desk, but the laboratory/workshop we use for our tests and video recordings is on lockdown due to the pandemic :/ If they won't reopen by summer, I'll try improvise these tests with some lighter equipment. Fortunately the BT2.0 is so small, that I likely won't need the big 600A supply to push it to its limits :)
Thanks! So molex is same as JST DS losi?
Could you make a video about wire gauges?
Yes! We have that on our short list, with just 2-3 things queued ahead of that. If we keep the new "one video every two weeks" schedule, we should have that reasonably soon.
You know what i'd like to see? Tests of just wire itself; the current each gauge of wire can handle continous and for 10 sec before desoldlering itself (test everything on xt90s so that it's just the wire not the connector overheating).
Hahaha, your timing is uncanny :) That's exactly the video I promised myself to finish this week! "Preview" here i.imgur.com/9wopE5y.jpg

I need it
Do you have any part number for this? The assembled connectors but without the wire.

Question is, where do you purchase pre-crimped with silicon wires like that , I haven't had much luck ,google isn't getting me good results.
Hobbyking has them: hobbyking.com/en_us/molex-2-0-2-pin-cable-male-connector-with-200mm-x-24awg-silicone-wire-5pcs.html. There also is a separate listing for 5x females.
Thanks
I would love if you guys tested the bt2.0 connector from betafpv compared to the molex and the xt30
We have that video almost done! Should post it next week! (Spoiler alert: It's a good connector, but not as great as the marketing material would suggest)
@@dronelab1280 sweet! Looking forward to that vid :)
How to buy please put link
Crimping tools can be had for as little as $20.
My drone has one of these. But the connector is a little bit loose and getting hot and my drone is not taking off. It shuts down. What should I do?
That's a tricky problem to debug. It could be faulty connector with bad contact, OR it could be something wrong with the drone - like an underperforming motor that takes a lot of extra power - with the hot connector only being a symptom of the extra power consumption.

What's the amperage rating for banana connectors or a real banana?
The banana you see is the reference "Banana for scale". It has a rating of one equivalent banana dose, denoted "B". This way we could do A-B testing with it and our Ampere meter. Banana plugs take 16A officially.
what is the ref for the specific tool please ?

@@dronelab1280 Thank you! I will look for it with that number.
Калькулятор электроника детектед!
Seems like molex straight out removed this connector from their catalog
How do you fix the fucking wire if it pulls out?!
LOL A SOVIET CALCULATOR
