Hey man, there is something diff with the new batteries that require a newer charger. Even if they charge with the old charger it won’t be to full capacity.
The knock offs are reacting the same way.
It has something to do with the newer “lifepro” or something like that battery type.
Note in the above image, I stuck with the older style battery packs. The charger that I have came with an XR style battery in the package.
