As noted in other posts, it appears the LIPO battery connector is backwards / opposite of every connector / battery leads I’ve ever seen. Can anyone confirm that the negative and positive terminals are indeed accurate as labeled on the board and on the product page? I don’t want to burn this thing out because a board was misprinted. If I plug a battery in the only way it will fit the polarity will be reversed.
The diagram in the “Battery usage” section of the Expansion board wiki is correct.
I have connected the battery as shown in this diagram.

Thank you for confirming!
yes this is very agrivating… i had to make a special pigtail to adapt my battery to the boards
i found some battery with the polarity reversed but they were much more expensive… and no way to know before purchasing that they are actually wired as indicated
in my case i found the battery i wanted and baught pigtales to adapt and used red and black wire shrink rap to indicate the actual polarity

I just got a cheap (EMB) battery of Amazon with the wrong polarity. If you have some small-bladed watchmaker’s screwdrivers then you can prise up the small plastic tabs on the connector, remove the wires and swap them around. It seems (…after 10 minutes charging!..) to be working ok.
yes… unfortunatly i think what happened is at the last minute the connector was switched from the bottom to the top of the board and it caused the polarity to switch.
