Very interesting piece! Contains everything I bought and soldered together myself for own projects.
Attached is the english version of the link
@Markus_Illenseer Aliexpress automatically switches to Russian. I’ve ticked everywhere possible that I prefer English language and want to go to global site. It reverts back to Russian in few clicks 
One bit more for you:
peace! (no battery, but who cares at this price)
@Markus_Illenseer when I will need battery, then I will use this:
And I will be very hapy if you could help me to figure out the name of the connector by which cell connects to the shield. It’s form-factor. The white one near microusb Solved. Battery is connected by XH-2 2.54 mm female connector.
p.s. friends I’ve intensiously switched to English on Ali, but when I paste the link here it immediately become in Russian language %)
p.p.s. I got it! My Google Plus is Russian! (While Chrome is not!)

Here are they, battery connectors!
Now I have told you everything I wanted. Wish you to find awesome cells and current/voltage sensing modules by yourself 
Good luck!

Maybe the ebay-link is more helpful?
I just bought mine here.
I am waiting since weeks for this setup to become available as ESP32
Nice - but is the connector + lead higher than the display? I wish people would put this on the OTHER side…
Got my boards this week, great to play with!
@Peter_Scargill The OLED is very flat, nearly everything on the board is higher. On the other side is the battery, which undoubtfully is not the best side to place the OLED 
Question: how would I connect an external antenna?
Any projects to recommend, aside weather station and planespotter?
@Markus_Illenseer second way (but the first one looks hmm… better 
) https://forum.pimatic.org/topic/2618/greater-wi-fi-area-for-esp8266-01-with-external-antenna/2
Hm. Will look into that, thanks!
