DLPNIRNANOEVM: what is the right type of external battery and its connector for DLPNIRNANOEVM?

Hi,

I've purchased one DLPNIRNANOEVM and trying to buy an battery to power it. I've read the user guide section 4.1, but it didn't tell what kind of battery connector it is.  Could you kindly to help:

1. what kind of connector I should choose (as attached pic 1),

2. and which side is positive/negative, No.1 or No.2(pic 2) ?

3. Tenergy 103450 is not available in China. Is a 3.7V 18650 battery with a protection board equivalent with Tenergy 103450?

Best,

Bian

Thanks for reaching out! But I'm sorry that we don't have related information either. You can try to measure it by the ruler and multlimeter or post it on the international E2E forum e2e.ti.com.
