hmm not what i was expecting in terms of service and warrantee.Hi all, official update from Seplos on my faulty unit. diode D4 is faulty on units produced before August 2021 as there was a bad batch of components installed. I have checked with a DVM and indeed its gone open circuit both ways. Their resolution is to send me a load of SMD didoes to repair myself which I'm not too happy about to be honest but I'm capable of doing so, others maybe not so. Also it concerns me from a warranty perspective as once I have soldered new components on the board where does my warranty stand? Also the board is covered in a thin epoxy/potting compound that needs to be removed carefully before remvoing or even testing the components.

hello,
"D4" has broken down. Before August, there was a batch of BMS "D4" because of the shortage of electronic materials, and the raw material suppliers because of the unstable supply channels, which caused the "D4" unqualified rate to increase. You can rest assured, we will be responsible.
Can you provide the model of your BMS and who sold it to you?
We apologize for the inconvenience caused to you.

i don't think this should be happening from a clear manufactoring fault ?
