Why is my computer randomly shutting down after iFixit battery install

Installed replacement battery from iFixit, they sent me a new one due to random shutdown. 2nd replacement battery has been in for 4 days and random shutdowns happening again (2x today). I’ve performed SMC reset and so far so good. Unit was not hot, so I don’t think it was a temperature shutdown. Can anybody make sense of this info captured from one of the shutdowns to help determine root cause? Thank you!
