MKR has a connector for LIPO, So you can connect LB-041 & LBB-041 to it.
But, You need to modify the LB-041 Cable (Robot Cable-2P for Battery Box (150mm)) to cross.
(2021-08-19 Addendum)
Swap polarities (crossing) of one connector as below image. If you do not make this modify, your MKR will heat up. There is a risk of failure.
You’re right. Thank you for pointing out.
I asked our intern who did this test, he said he had swapped polarities of the cables.
Very important information was missing
I amend my post.
I have smoked up boards in the past from this problem. Although many dev board manufactures use this connector and many 1s lipo manufactures use this connector there isn’t a standard polarity
Hi @shiba_8ro, that makes sense and is understandable. Thanks for editing the post to add in the extra information! I was just confused that I had somehow not wired mine correctly or somehow found non-standard cables.
Based on this discussion, it could be a useful basic tutorial idea to show how users can re-pin their cables if needed for custom projects
