Everyone wants to grumble on this forum section about vendors who don’t deliver what‘s promised, so I thought it was a good idea to mention a supplier being honest enough to give me good advice, even at the cost of making a sale. That supplier? Amy Wan.
I contacted Amy because I wanted to buy 4 more cells to make 8 in total so I can connect them 4S2P in the configuration shown in below photo. Ignore the text which says Eve 560Ah, with LiShen cells it would be 544Ah. She not only advised me that the Lishen cells which other vendors are selling are old stock because LiShen does not sell grade B cells to the reseller market any more and have not done so for years, she also advised me against buying the Eve 280k cells and using them mixed with LiShens in below arrangement as the internal construction is different (Eve being a wet cell with liquid electrolyte which can be heard moving around if the cell is shaken).
I think it’s worth recognising when a supplier prefers to point a customer to the right solution for them, even if it costs them the sale. And in doing so she sent me a lot of messages over a series of days, so top service from Luyuan ?
ps. the conclusion we reached was the best option for me would be to buy LiShen B grade old stock from one of the sellers who still have them, but at least i do so knowing what I’m getting.
