The battery status just shows 1% and a message saying, “battery is not charging”.

It sounds like either the replacement battery is no good (which sometimes happens) or there was some damage to the battery or main logic board during installation. If you still have the original battery you were replacing, and it’s in decent enough shape after the removal, and it was able to take some charge before it was removed, you can try reinstalling the original battery to see if the charging issue is isolated to the replacement battery. This is a pain, though, because it involves removing the battery you just installed (you may need safe double-sided tape to reinstall later). If the issue persists with a separate battery installed, you can feel confident the cause is not the battery, in which case the issue is deeper, possibly on the main logic board level. Otherwise, you are probably liable for some sort of return and would need to order another replacement battery.
Hope this helps!
Hello. I’ve had the same problem. My original battery failed and two replacements have also failed. The cell voltage seems fine but the “pack” voltage where the BMS board connects to the rest is 2.2 V. It might read 2.2 V because the BMS FET has turned off. When trying to charge the pack voltage fluctuates between 10~11 V. One replacement failed because the bus wire that connects the cells rubbed against the sharp aluminum edge of the case and shorted.
