LiPo battery recommendation for nrf5340 Audio DK

[SNJY]

I would like to know the recommended battery part that is suggested by nordic to work with the nrf5340 Audio DK. I saw some blogposts where it was mentioned that a 3.7V 1500mah lipo battery comes with the kit. I am assuming due to shipping restrictions on batteries, I didn't receive a battery in my kits. 

Regardless, i would like to buy a battery to start testing the board battery-powered. I couldn't find much details on the specifications for the battery in any nrf5340 Audio DK documentation. Can you please recommend be a list of suggested battery parts which i can procure for my application?

Hi,

In the past, nrf5340_audio-dk packages included the battery, but this is not the case anymore. For your reference, the battery that was provided with the nrf5340_audio-dk board was LiPo battery 3.7 V, 1500mAh.

Can you please recommend be a list of suggested battery parts which i can procure for my application? 

You could try to look for battery with the same specifications as previously mentioned. You could get more information about available parts from your local distributor.

Please let me know if you have any further questions.

Best regards,
Dejan

While i am able to get a battery with 3.7V 1500mAh capacity, i am not able to get one with the same 3 pin JST connector with a thermistor signal pin coming out. Having a part number of the one sent previously with the kit would help me to look for similar products

Hi,

This is the information shown on the battery - LiPo Battery 3.7V LP803450 1500mAh. Please let me know if you need further information.

Hi dejans,

i looked for this part online and found a couple of options. But none can be directly used with the nrf5340 Audio DK kit. None of those had the 3 pin JST-SH connector with an NTC pin. Is it possible for you to find any more information on the exact part that was shipped earlier with the kits?

Hi,

You can find specific information about the battery in the Bill of Material specification located in the nRF5340_audio-dk hardware files.

Best regards,
Dejan

Thanks for sharing the link for the BOM and hardware files. I couldnt get much information on the exact manufacturer's part number for the LiPo battery that was sent with the kit previously.

Alternatively, I have ordered a similar battery with wires and ordered the mating connector (cable assembly) for J3 connector the nrf5340-AudioDK kit.

I will try this out and let you know if this setup works for me.
