Fitting opto-isolators to the super capacitor protections boards.
I have 2 70wv 27,000uf caps are they considered “super”cap?
weird and probably stupid question but…can I rearrange the circuit on a 60S, 160V BMS PCB without disassembling it? As in by drilling out or otherwise severing and and then reverse wiring connections turning it into a 6S 10P board? It's a high end bank and I really don't want to completely destroy the board…nor desolder 60 capacitors – ugh…or, barring that, how do I step it down to a more common voltage?
you're going to put the optos in series so it only signals when all are charged or you will use some multiplexers to pass to the controller which ones are ready ?
I'm surprised you did not design custom protection boards by this time.
im not sure i understand the thinking on that lay out . i would imagine keeping the shunt in place too lower any over voltage would be usefull and then use the opto's on the points you see the led's on would work best so you still have a safty feature as well as your power shut down .
please help to make solar charge control
solar = 330W
battery = i dont know
load = 100w
For mounting, I would have suggested drill the holes 1 size too small (over here you can get saws in 1/4 to 1/8 inch steps depending on needs) and then cut the wood lengthwise and put screws thru to firmly clamp the caps between them.
What caps are those?
can you share the updated PCB stl (whatever PCB formats use), is there a video on building the super caps and what is the tool your using to pick up the SMD components?
I was just wondering where that useful little soldering iron stand came from? I just typically use a regular stand doesn't necessarily fit that great but it works that one seems very simple useful I've printed a few different designs on my 3D printer to hold the irons but none that I fell in love with not one's not anything special I'm sure I could probably get one from China but was curious where you got that one?
Also I was wondering if you were to change the values on those load resistors would that change I'm assuming those are for discharge but I don't know exactly. I'm asking because I'm looking at changing them on my liitokala li500 charger. Would like to try to change them to get it to discharge more It says that it discharges at 1000mA But that is not the case would actually like to be able to discharge it at one amp just curious if I could make that happen by changing the load resistors on the charger? Look forward to hearing from you thanks!
Also nice content keep it up!
In theory those optos work great in this setup but.. The combined way the transistor sides are in parallel they come on too early without a load. I tried this before. You really need Schmitt trigger opto isolators is what I found.
I was looking for the 12 volt light bulbs but haven't found any. Do you remember where you sourced them
