LiliGo T-Deck onboard battery connector polarity

Support
1

Hi, I am going to buy internal 3.7V Li-Po battery for the T-Deck that has not arrived yet. But I cannot tell the polarity of its onboard battery connector by looking at the Lilygo product page.

Can anyone confirm which side is positive and which is negative? Thank you

Can anyone confirm the JST size, seems smaller possibly <2mm pitch.

1.25, hard to find sometimes.

Needs to be designed out, batteries are always the last consideration.

Will try these and report back. https://www.amazon.co.uk/LIR2450-Rechargeable-Battery-Charger-Lithium-ion/dp/B08CRCL42T/ref=sr_1_2?crid=4LZHK43FTMEJ&dib=eyJ2IjoiMSJ9.0wANiKL67l8YdfheSI9Alk54iI7okD3FWQnsSKH6mQ0HG6VwrWSoD-XYjceMtODF1_5kDv1n700aMlezEoljCEXeGP7g4YZte5TZo1Tx6Nan3meOAxaa1MO8tUFDfDKq1J-6Zn0adJ3lqTtgxpjh68nLUXz5OHQVXgCVAkALEQWttWTJ3rGejAxeCpm79yJF_Aher6CM0cKayobUlKLEPOUQWnW_h22KQNyR2SGEUbU.o_3iKI6BNR4Pm86zJL3_g2i7aXUtVEZXgnKsIznNtiw&dib_tag=se&keywords=eebm+2450+rechargeable&qid=1715208780&sprefix=eebm+2450+rechargeable%2Caps%2C116&sr=8-2

May do a JLPCB run if enough folks are interested. Rechargeable and recylable coin cells are mucho grande.
