Letool 30 Pairs JST 1.25mm 2 Pin Micro Male Female Connector Plug with Red Black Wire Cable 80mm

Good quality, fits perfectly

These work well and are as expected. Be sure to check the amps running through the small connector, Its not a large one and can only support about 2A as specified by the connector size and type. More info about this would be great on the sellers page, but I am reviewing the product and not their product page.The first thing I did was to snap these all together for easier handling. I ended up with an odd one out. My first thought was that i was shorted, but after counting, there are 61 total connectors, 30 pairs and one odd extra male side connector.Ill buy more when I run out. Cost for wires and small connectors is kind of high, but not having to wire up the connectors and save time is worth it to me.

Worked great for 5015 fan for my 3d printer. Had to change the plug to match my printers PCB. The plug worked fine, but as stated in description, the wire polarity was wrong. After I swapped red/black and soldered, it worked fine. Just keep that in mind when you are using these.

well let me tell you if you need 1.25 JST 2 pin connectors then these would be the ones you'll want to get there priced right good quality wire was used and you don't have to make them, I do alot of RC car and truck building and these JST connectors are the cats meow when you don't have to make them or you need them and don't have them so pick up a set and try them out you can't go wrong, I didn't and I'm happy I don't have to make them anymore.

My Blade Nano S3 toy helicopter suddenly had developed very short flight times with otherwise good batteries -- What was going on? I read somewhere someone had a similar situation that resolved when they replaced the battery connector/cable. I didn't think this was going to work but boy was I surprised when replacing the existing battery cable/connector completely restored normal flight times! I speculate the old cable had been damaged via repeated crashes, but at any rate, these connectors have been very useful to me! Final note -- other reviewers state the polarity of these connectors is reversed, but for the female connector I used the polarity was as expected -- red is + black is -.

Be careful!! The polarity of this product did not match the polarity of OXWINOU batteries, also from Amazon.I don't know yet which one is wrong.

The wires were much smaller in diameter than I thought they would be. But that just allows more flexibility and truthfully, are all I will normally ever use in my projects. Nice long wire lengths and the connectors are very small but tough.

i use these for all kinds of things in a 12v systems
