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.
 
To update, AliExpress found my dispute to be valid and offered a 50% refund without returning the cells. I accepted that offer and now just waiting for the funds to hit my CC.
 
But, how did your test go?
Well, I was able to assemble four cells into a battery with BMS over the weekend and now still waiting for it to charge completely. I have limited charging and testing capabilities so hopefully later this week will be able to test at least four cells.
