Thank you, I will give that a try.
Thanks, maybe it was just tangled filament ๐ค, but I will do a cold pull anyways.
I was printing PLA, it looks ok up to a certain height (although it was warping slightly), but then it becomes ugly. I will do a test print of the same height, butaybe you already have an idea.
In addition to the other answers: You are mistaken regarding stress and losses on battery cell level, at least if you build the same overall batterry capacity at both voltage levels with the same cells.
Starting with the HV variant, the power is P = U * I. If you now build a LV variant, let's say at U/4, with the same capacity, you will have 4 strains in parallel. So on pack level you will need 4 * I to get the same power, but inside the battery this current will split up into the 4 parallel strains. So each cell therefore again only has the current I.
Of course this is an ideal assumption. As you would have higher losses, e.g. in the wiring to the inverter, the overall power you need to draw from the battery increases. But it's not as severe as it might seem based overall current increase on system level.
Edit: The formulas did some unintended formatting. ๐
Maybe it was just tangled filament?๐ค
White my test print from afterwards (after unspooling the last two meters from my first self rolled spool ๐ ), grey a print from a few days ago.
