BenderIsGreat34I wonder how much runtime an Amstrad PPC512S would get if it had a modern day lithium ion battery installed where the D cells would go. I should go on sabbatical for a few months and find out. We can call it my midlife crisis.

@andymoose Pretty shure you can even get a long range with just some #LiFePO4 cells…
- Either way you'll have to adjust the voltage inputs and I'd highly recommend to add in some proper BMS to prevent critical discharge...
