Hi JasonI do have one of my 8 packs that is wired differently and I fixed it by redoing the connectors to the white OEM connector. I suspect that TE connector more than anything.
Are you reading the Volt on the TE connector or the BYD battery connector?
Put your volt meter - on the battery -.
Next, write down each reading on each pin of the 32 pin connector.
Only 8 will have any value, don't use the end that looks like the battgo connector end.
That 4.865 reading on the Battgo is what mine would show when one of the wires is disconnected.
Can you send me a copy of the other battery connector pinout?
Thanks
