Since we're not talking about what those prices are, it's difficult to engage. BUT there are good Aliexpress sellers. There's a good chance several are the same source your employer buys from. THAT is the tough one to sort out. Look I'm not defending the thieves on Aliexpress. I am saying, there are decent fellows selling there, and you are painting with a pretty broad brush. I recently learned that one such maker sells to several other China resellers. The hard part is sorting who those good guys are. I'm not going to shill for them but some basic searching here and on ES Facebook will sort a couple.
Those who live in fear of "China cells" are off track as well. Some "brand name" cells are produced there and one China brand is so reliable and in demand that their price point is higher than the brands extolled on ES. So while our fears are generally with merit, I think they're to broad.
The prices can be 10% to 20% below the USA discounters. The biggest problem is warranty. I have the folks I use sell me a replacement BMS WITH the pack I buy. Usually around $12-$16. Several USA suppliers will also send a new BMS. The biggest warranty problem is shipping. But the number of fails is really quite low when we consider the actual numbers sold. Unfortunately the loudest noises here come from the relatively rare failures. Which leads me to why I despise vendor complaints. Shit happens. It happens to the best resellers.
I hope to see folks like EM3ev expand their choices. I have my original battery from them that has been well cared for and is almost as new after 3 years.
The market seems to be catering to the high power crowd. Apparently those of us happy at 36V are dinosaurs.
Thanks for the exchange. My opinions and experience pale in comparison to yours and I mean no disrespect.
