Me too! I hope to eventually replace with superior 3rd party packs such as this one:
Our Next Energy (ONE), a two-year-old Michigan startup, said on Wednesday it had tested a prototype of its new battery in a Tesla Model S, driving 752 miles (1,210 kilometers) before recharging.

@wk057, if an owner went cheap and replaced some pack modules with unmatched ones, the bms will shutoff the car unexpectedly when any cells reach 3.1 volts, right? I assume we could monitor individual voltages via ScanMyTesla to learn when the pack will shuts off, like 170 miles for example.
If all cell were top-balanced at 100% 4.2 volts, can we update the screen or bms to calibrate for 170 miles and update the SOC % display? To make driving reliable although degraded.
I saw someone post proof of concept on TMC= supercharging a chevy volt pack, and the Model S instrument cluster displayed 38 miles and a close to full battery icon.
