Using 4S lipo to power the NUC (need converter or not ?)

[sebastienp]

Hi,

Electrical rating of my NUC is 19V - 6.32A.

I have a NUC10i7FNK2, and i want to use my lipo 4s (12.4V-16.8V) to supply power to my NUC.

First, I had thought of taking a converter (https://www.amazon.fr/sourcingmap%C2%AE-Imperm%C3%A9able-Puissance-Convertisseur-R%C3%A9gulateur/dp/B01H97ET2Q#customerReviews)

Finally, Can i use directly Lipo 4s or i need a converter fot this ? (I specify that i supply other module with the lipo 4s).

thanks for help,

Sébastien.

Hello sebastienp,  

Thank you for posting on the Intel® communities.   

In order to better assist you, please provide the following:  

1. Can you provide more details about how are you planning to use your NUC with the 4S lipo?

2. Are the other modules mentioned also NUCS? If so, can you provide the model name

3. Do you want to use the 4S lipo instead of the power supply or the power cord?

Hi Deivid,

Thank you for reply.

1. We want use NUC with Lipo 4s for an aerial robotic application. So, the weight constrainst for converter remain important.

2. Other mentionned module are independent of NUC. But we use two camera (connected and supply by NUC - d455-)

3- yes, i can't use power supply of the power cord. We need a small and lightweight converter if possible.

Thanks,

Regards,

In the past, I have always recommended using a Buck (DC-to-DC) Converter between battery and NUC. There is one that was specific to the NUCs (though smaller amperage requirements then): Mini-Box.com: DCDC-NUC, 6-48V automotive power supply for NUC, 12V or 19V output.

Remember that you must ensure that the battery chosen can support both the NUC's current requirements (19V - 6.32A) and any loss through the Buck Converter.

Hope this helps,

Hi Scott,

Thanks you for reply,

Yes battery spec. support current requirements (19V - 6.32A).

I have already check DCDC-NUC but is too large for my appliction. (it's 160x45x30 mm and we need approximately 70x30x25 max)... I think a cheap converter could be fine ? Thank you for help. I'm still looking for a converter like this : https://www.patrickmodelisme.com/castle-creations-cc-bec-2-0-etanche-15a-4-8-12v-2-14s.html but with a range of 12v-19v.

Regards,

Sébastien.

Let us know how things progress. There have been other folks who inquired about car, boat and even telescope installations, but none of them have come back and given us a good explanation of exactly what they ended up using/doing.
