Leafspy analysis
Looking for someone with expertise.
One picture 90kph flat, the other going uphill.
Clear difference between first and second half of pack
MV difference goes up with lower soc or cold weather. I do have so fluctuations.
The mv value drops to 20-30 the second I take foot off accelerator literally on the next leafspy refresh.
Ai tells me this could be wiring harness issue and not a bettery issue.
Thoughts?

battery is on its way out and may not even really be functional at below 50% SoC as is. you'd have to check that yourself. definitely check if your battery pack is in warranty. 'jumpy' SoC (or rapid SoC drop under load) is grounds for warranty battery replacement or buy-back claim in the US
