Based upon what? If it's what Leaf Spy says, I suspect that value that you're looking at is based upon the Wh/gids setting that defaults to 77.5. If you raise that, then for a given state of charge, the kWh indicator will go up. If you lower it, it'll go down. Try it.
We have no idea what that setting really should be and what caveats there are about its accuracy, what ranges/conditions it's not accurate or what ranges are where you should use a different Wh/gids constant.
ok. right now I don't know what LEAF Spy is set on but its been on same setting for years and I believe it is 77.5. so should I set it to 80?
It honestly doesn't matter where you set it. It's a calculated value from the GIDs reading. You can't really use it for anything. All the important stuff is calculated from the GIDs (LBW, VLB, turtle, and pack disconnect). Given that the battery is advertised as 30KWH and that there's 4-5% buffer at the top (4.11vdc cell voltage vs 4.17vdc for a fully charged Li-ion battery and 1.37vdc differential between full and empty (2.8vdc)) and a couple of percent at the bottom to avoid killing the battery, 28KWH is a good guess for a new battery. There seems to be a bit of a lottery effect for the battery capacity with as new values reported at 74 to 82 KWH. Build date and/or time on the lot might be affecting this but we don't have enough data yet.
