Glad you avoided a problem.

The Alibaba protection process went pretty smooth. I submitted my evidence and offered to keep the product if the seller would give me a partial refund, which the seller agreed to and Alibaba issued the partial refund to my credit card in a timely manner. One needs to be careful with their time...

It was pretty close to on-time except for a FedEx mix up that dropped off 2 of the 8 boxes one day and didn’t get the other 6 boxes to us till 8 days later.

All but four cells tested less than 280Ah.

It didn’t go well. The order was for 16 new Grade A Eve 280Ah cells matched for capacity and IR. I received 13 Eve cells and 3 of another brand. The Eve QR code’s showed all but one was manufactured in 2018 and the other in 2019. They tested from 267Ah to 285Ah. Therefore none of the...

I’m assembling a (16) 280ah cell, 4P4S pack for a sail catamaran and plan to house it in a large Pelican case to provide restraint and some measure of protection from the salt air and moisture. Max charge current will be around 150A and max load current around 250A for limited duration. I plan...

Well I’m told I got the last of their Eve LF280 stock. Should have (16) cells to test in a month or so. Final price was $7 per cell plus $251 shipping door to door. Cici was good to deal with; reasonable, communicative, responsive and good with English. They are supposed to send a video of...

What is the best practice for optimally arranging cells based on variation in capacity and internal resistance within the pack? It would seem it would be most important to match internal resistance in the parallel cell groupings, but how should variations in capacity be grouped? Would it be...

Shenzhen Qishou Technology Co. Ltd has a really great price on Eve 280ah LFP cells. Has anyone ordered from them before?

Yes, I was thinking in terms of software and didn’t realize both pins were available for each output. I thought they were wet contacts rather than dry. I’m not familiar with optocouplers, my experience is in line-voltage AC controls with industrial relays. I have a Xantrex SW3012...

I assume Type 1 thru 4 go high when condition is met. Is it possible to invert these outputs? Thanks!
