Hi there. I'm new to solar and lifepo batteries but have been researching for a while now. I recently received 8x 3.2v 100ah VariCore cells from AliExpress to find that these are grade-B cells that are swollen. I've contacted the seller with my concerns, but they insist "...there is no problem." I have now filed a dispute with Ali. Should I wait for the results of the dispute or should I capacity test the cells? Any other recommendations for next steps? Thank you.
