So I stumbled across these entries at a GM Parts Direct web site. Does anyone know what changed in a second Bolt EV battery design?

Does this mean we only have 57 kWh available with 3 kWh as buffers? Does this mean we have 1.5 kWh top and bottom buffer?LG Electronics

I think he's referring to the low voltage error that ends up stranding Bolts that a small number of early production Bolts suffered.The professor in the video mentioned an issue where the car would estimate a higher range than what’s actual with the previous battery version.
Fast forward to around 4:45 in that second tear down video.

The label, on ours, is on the side of the pack, just to the rear of the seam between the front and rear door. I slid a mirror along the garage floor under the rocker panel until I found it. Then I stuck a camera under, and took a picture. I'd love to know if anybody before the VIN he listed has that second label.Mine was built 4/17 and my vin is 57482 so I guess that means I have version # 1. I have not looked under the car yet but will next month when I do my first rotation.
Yeah. That low voltage error is exactly what you would get if one of your cells was below spec. Since these packs are top balanced, a slightly low capacity cell's voltage doesn't fall off the cliff until you get down to those last few miles remaining. One of my questions is; Did they just reprogram the computer to show less range for the last bar or two on later cars, and change the label from 60 kWh to 57 kWh?I think he's referring to the low voltage error that ends up stranding Bolts that a small number of early production Bolts suffered.
Well, ours is 13----, and I have driven it down to the dregs several times. If this means I got the battery GM originally claimed, and you didn't, I don't know how thrilled I'd be.Build date 10/17 and VIN is 18----
Wohoo!?
