YEs this is good. since you can use the logi to power the PSU,s thats a good way to go. or just set the PSUs to always-on via the logic, and switch the mains, which is what I do.
always a good move. usually, when going to charge something, I set to a voltage close to the battery (50V) and have the current limited to like 1A, then connect the output/
yes totally fine. if there is no output there is no current, but the voltage will go up. To be safe you can use a dmm and measure the output of the converter and see if its over-spec or something. like set to 50.4v and measure. anything within a few thents of a volt is fine. the actual battery will only be charged to the cutoff of the BMS.
Remember that if you power on with a battery as a source , you dont have the current protection of the PSUs. unless you’re in a rush, i would build the PSU stack first. and test with that
A diy charger (bench top power supply really) with variable voltage and amperage. Can charge any battery up to 22s at 20a or 14s at 50a , depending on components.
Generally can be built for under $200 from the converter, several used server supplies and and old pc case.
it has all good info, with only the occasional drill shart noise interruption. The issue being you need to watch it more than once to really understand from a beginner perspective, and it seems daunting and confusing with all the info not following along at the same time.
Personally would have preferred a bunch of steps with explications and pictures but maybe that is out there already, haven’t really looked.
Can’t really nitpick free knowledge! too much at least
as far as isolation. you just have to look it up before hand. I recommend getting other supplies if you cant find a clear answer pretty much immediately.
