To OP: Post #1 response.
I've been at this a wee while shall we say and have seen many folks do many nasty things to batteries, cells & equipment and 90% of it, is directly a result of NOT reading Instructions, Manuals & Documents. People have always had an issue hence the term RTFM (Read The Frappin Manual) came out Years Ago. There are also many pre-conceptions that people refuse to change and will not even take the time to engage a bit of Critical Thinking either... for example, many foolish people have this notion that you can only use 12V Solar Panels on a 12V Battery System & SCC, also that somehow 12V panels are superior that larger capacity ones... seriously, some do believe that. I won't add more to that other than to say, there are always a Select Few who think they know more than the Engineers who designed built whatever... many educated via Youtube University and don't even own a DVOM.
A very common thing as well, especially with BMS' some think these are Magical Wizardly Devices that can cure sick batteries, recover dead ones and solve User Caused Mistakes. Sorry utt they DON'T ! They have a simple task to do and that is to Guard the cells and protect the pack they control. Depending on TYPE OF BMS, some have Multiple Chemistry Support such as LFP, LITO, LIPO, Li-Ion etc and these MUST be set for the correct chemistry & profile BUT some not paying attention have left an Incorrect choice, such a LIPO on an LFP Pack, that WILL Overcharge the cells (cutoff for LIPO = 4.35V per cell). They (BMS) "may" be able to do basic Passive Balancing (really only good for Perfectly Matched & Binned Cells) and not much use on cells above 200AH. Some can do Active Balancing and depending the Balancer Capacity (in Amps) these can deal with larger cells.
DUE DILIGENCE:
My Goodness, this is a BIGGY ! This is DIY Land not Plug & Play Village, so due diligence on taking equipment and setting it up properly is an absolute MUST. That also means checking "every" wire, connection made, testing Crimped & Soldered connection & connectors for good continuity, A LOT of problems come up because of a wire faults or poor connections, bad soldered leads or something like that. A Common one is BURS on BusBars or Terminals that prevent a good solid contact, which seems few pay attention to (maybe they think over tightening the connection will bury a Bur into the other metal ?) For those making their own BusBars, often forget to "chamfer" the bolt holes to ensure they are perfectly clean & clear.
Lastly and not least important is that this is the 21st Century, personal responsibility is a "Bad Ideation", it is always someone or something else s fault, always deflect responsibility & ownership of any & all problems elsewhere. Of course ALWAYS Blame Import Stuff it is ALL pure Junk right.... especially if the Particular Nation producing it is a Target by ... whatever ding-a-ling excuse that can be raised by the Chicken Little's and Fearful Shrews who rant and rave against everything that is outside of their tiny little domain in the universe. THIS IS BAD ENOUGH, that when they get knickers in such a tight knot, they start accusing people, companies of things, they escalate that into personal battles to "win being who is right" and even go as far as making Threats... I have Experienced all of that HERE and this is only recently as some dregs tossed from other boards have shown up here with their idiocy...
I'll continue help those that are genuinely interested & keen to learn and am now very selective what threads or posts I will help on. I may chime in once in a while in a thread to Suggest people engage CRITICAL THINKING, or to look at the "ABOUT MY SYSTEM" pages from some of the "advice givers" (because poor 'advisors' often none) because they are being fed Feldergarb ! I swear some give the advice to destroy stuff at the expense of the others and they seem to get a sick kick out of it, that someone believed them and fried thousands of dollars worth of gear. Hence the "Engage Critical Thinking" part comes into play.
BTW, If you hadn't realized it yet, I am a Chargery GUY, infactt I introduced Chargery BMS here back in November or December ? I forget now... I am JUST A USER of their products but redid their manuals and help Jason to improve the product for the benefit of EVERYONE and I do this entirely Free & Voluntarily, I get NOTHING out of it but the satisfaction that I helped people & a company to get further ahead with a better product. Many have offered their Thanks for the effort & that is appreciated BUT I have also been "attacked" and that does not wash ! It's this simple If Someone wants to threaten me, Go Ahead, show up with a 3.08 & Body Bag in hand so I can send them home when they fail. (never screw with a dead man walking, it's a one way trip)
