Hi there.
I have bought a nanopi2 hardware. there are 2 pads on the board between RAM chip and WiFi module, seems to be for battery wire soldering. Is it correct?
and if correct, which type of battery could be connected? rechargeable battery or non-rechargeable CR20xx type?

Hi I am not quite sure which points you referred to . I would guess you referred to the two points I marked in the attached screenshot. If my guess is correct yes they are for RTC. It is for non-rechargeable 3~6V battery

hi
you guessed right & it is excellent that this board has RTC backup battery holder.
Thanks for your guide.

Can you please confirm the correct polarity:

[_] -> +
O -> -

Is this correct?
