I hope this helps others who might have purchased these very messy BMS cards.
Has anyone had experience with these BMS cards? They are available from ebay or amazon for about $15, yet have manufacture errors in alignment of the chip sets. If the uploaded images come through, I've highlighted a 1 mm chip that is 1 mm out of alignment in the exact same spot across all 4 cards.
The engineer who built the battery recons it doesn't make a difference. But the battery pack doesn't discharge properly.
What are your thoughts? Defect or not defective?
How would the error show up? I first ID it using a volt meter. Only one cell column ever discharged and completely discharged, beyond recovery.
Any thoughts greatly appreciated.
