Does anyone know if the standard connector you find on most whoop boards is a JST 3 pin 1.5mm connector? Like these. https://www.aliexpress.com/item/32840289...npA7tCw6C2 I want to buy a bunch of them so I can easily connect motors to boards with connectors, when the motors come with bare wire. Thanks.

For most (whoops, at least) the motor connectors are JST 1.25.
For the smaller NewBeeDrone units (the AcroBee65, for example), the motor connectors are JST 1.0. • Posts: 2,381 Threads: 74 Likes Received: 1,338 in 998 posts Likes Given: 781 Joined: Apr 2022 Reputation: 41 04-Jan-2024, 09:52 PM (This post was last modified: 04-Jan-2024, 09:53 PM by Pathfinder075.) I ordered a pack of 20 with wires from Ali. I also ordered several Darwin 15A AIO's. I intend to chop the wires, solder in a 3 pin connector, maybe a JST GH ,then the other side goes on the motor wire. i get plug and play motors and less soldering.  Try Not, Do or Do Not

soldering is more secure and handles FAR more amps. • Posts: 2,381 Threads: 74 Likes Received: 1,338 in 998 posts Likes Given: 781 Joined: Apr 2022 Reputation: 41 For 99 out of 100 people soldering will probably be fine, but i'm the 1 and with my issues, connectors make more sense. Also none of the motors I want to use with them use any more than 12A. it's not like I'm trying to put a connector on a 2207, most of the stuff I fly is 14xx, 13xx or 12xx and all tend to top out at around 12A or less on amp draw, with most not hitting 8A on the sizes I use. Most of the motors I run come with them, very few don't. The wire on the 1202.5 is the same gauge as the BT2.0 leads I have, so should be able to address around 10A without issue, which is what I aim for in max usage on any motors I run on micros.
So for instance the 1303.5 on GF 2540 props at 90% uses 9.65A (90% throttle) according to the test data. So from that i can speculate that they will be fine with connectors on them. The 1202.5 on GF 2020 at 100% uses 7.7A according to that test data. They came with connectors.
For my usage requirements they will work. They might not for anyone else. Try Not, Do or Do Not

Connectors don't work on motors that probably use more than 10A, but most Micros don't use motors big enough for it to be an issue. Even the HM 1404's I have don't come close to the limits of a connector (6A on GF 3018 @ 100%). Also on the higher voltage packs it should be less of an issue. But as to what i am building, it can be answered in one word. "Lots".  Try Not, Do or Do Not

Yeah, I am late to the game here, anyway:
The connectors are JST 1.25 3-Pin these ones on AliExpress.
In fact, they have silicone wires. I have never used AliExpress,
but I like these ones so I might just have to place an order
myself.
Just a note: I burnt a 12A ESC using a 1303 motor. I don't know what
the motor's amp rating was, but it pulled more than 12A. Hmm.  
Later, iFly  Yeah the ones I have, according to the test data, will use 11.96A on GF 2540 at 100% throttle. But at 90%, they use under 10A, so my plan was to limit to 90% and run on HQ 2.5x3.5x3. I don't know if that is logically sound, but it seemed a good idea to limit output and use less aggressive props. But right now I could see me using a bigger ESC, since I have now used the 12A FC for the 1404 build. Try Not, Do or Do Not

Hi Pathfinder, It will probably be fine. I would keep an eye on the AMPS in the OSD, at least for the first flights. In my case, maybe my motors didn't pull the amps and something else blew the ESC. Yeah, I don't know for sure. It could have just been my perception, still, I started buying 20A ESCs just to be safe. I am interested to see what you think of the Darwin 15A boards especially with the larger motors. Later, iFly • |
