Suitable connector type for nPM1300EK's J1 connector

[SemihAydin]

Dear Nordic Team,

Could you please help me to find the exact product which I can use to connect my two wire 0.37Wh 100mAh 3.7V 351525 Li-Po battery to the nPM1300-EK for battery profiling. The battery doesn't has connector yet just has 2 wires(it doesn't has NTC) I'm planning to solder it if I can find proper connector.
Its also ok for me, if its possible to connect to the wires directly to the board for battery profiling. Because unfortunately the jst connectors I ordered int Turkey didn't fit.. Thats why I wanted to ask in here.

Also if there is any document or video to make proper battery profiling, I would be grateful if you could share with us.

Thanks for you support.

Best regards,

Semih Aydın

Hi,

nPM1300-EK hardware files, including full BOM, is available here:

JST 1 mm is the matching contact for that header.

Also if there is any document or video to make proper battery profiling, I would be grateful if you could share with us.

Documentation for the EK can be found here: https://docs.nordicsemi.com/bundle/ug_npm1300_ek/page/UG/nPM1300_EK/extension_board_if.html

There is a video here using the npm power up pc tool: https://www.youtube.com/watch?v=0eolgIk1KHE

 

Kind regards,

I believe you're looking for a female JST SH 2-pin connector.  I created an adapter using https://www.amazon.com/dp/B0FH4QRHH4 on the EK side and it fit fine. I don't have a link for Turkey, but hopefully that gives you the info you need.

Make sure to double-check that the polarity matches what the board expects.  I've blown a board out before by messing that up.

Hi Hakon,

Thanks for the sharing all great informations, I didn't find suitable JST connector yet but I wanted to ask if I can use P1 pin header's VBat and GND with using jumper to connect 10kOhm resistor pin to NTC on P3 instead of using J1 connector?

Best regards,

Hi Scigrapher,

Thank for your idea, I just want to check if I misunderstood. You removed the header J1 from EK and soldered new header on EK right? I will definitely try that if I can'T find connector or any other connection option on NPM1300-EK.

Also sorry for your board :'(

No, I bought that from Amazon and used it to make an adapter between the EK and my battery because it had the wrong connector on it.  If your battery just has 2 wires and no connector on the end, you would be able to connect the wires from the female JST SH 2-pin connector (which also has wires) to the battery's wires.  The female side should fit into the plug on the EK.  Ignore the male connectors that came with it (or find another unrelated use for them).  You won't need to desolder or otherwise modify the EK.
