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

Good product and great value.

Worked as it should.

CHECK YOUR POLARITY! I researched for hours and this was the only 2 day delivery product, 1) I don’t need 30 of them 2) the polarity is off but I payed attention and just switched it and everything works fine. The female and male bits connect together securely, after figuring out the polarity difference I got everything fit together and working fine.

I verify that 30 pairs were packaged and they arrived neatly separated. Each connector fit in the corresponding wire snugly, as well as the connector on the board that I am working on. Visually inspected each cable and did not notice any flaws. Wires indeed have the correct polarity. Tested the cable and verified that the correct voltage was present. Cables were able to withstand a reasonable amount of tugging. Maintained a good quality connection and works great at a reasonable price. I now have enough connectors for many projects to come!

Wow, what's with all the bad reviews saying that the connector is too big, doesn't fit, won't handle enough current and melts, etc. You all need to read the description and know what you need. Ask seller if you are not sure. One person needed Jst-ph which has 2.0mm according to the standard. Why someone would order something with 1.25mm pitch - obviously won't fit - and then complain, is beyond my understanding. These are fine. Description says "Pin / hole: 1.25mm-2P pitch" and pitch means distance between pins. 1.25mm is very small so its not going to stand up to being plugged in and out frequently. Connectors follow standards. Look for Jst 1.25mm on wikipedia and you'll see what these are, the dimensions and current rating. I purchased them knowing these were either JST-GH or Molex Pico blade. I posted a question and the seller never answered. I ordered them to take a chance and they fit the connector on the led strip boards I have. But I'm still not sure what they are and would like to know. Wikipedia says people confuse Jst GH and pico blade frequently since they are almost - but not quite - identical. I'm about 90% sure these are Molex Pico blade from looking at the wikipedia mechanical drawings. I'm happy with these and will probably order some more. If anyone knows a supplier of these with 4 pins instead of 2, please reply.

I use them all the time. Good value for a good product

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.
