soldering series connections, if you are making a flex pack
solder in balance connections and routing them
fish paper, kapton, and masking for insulation and abrasive resistance.
solder or crimp the balance wires to the JST plug/port on the bms
heat shrink the packs
solder main terminals, and BMS connections
If it’s being sold with a charger and BMS
charge the pack
adjust the end voltage /amperage of the charger, and ensure bms is functional and balances
discharge the pack to storage voltage for shipping
Now let’s talk about how many real hours it takes to build a battery. Not just the spot welding. You think you can do all that in 2? Even 4??? Okkkkkk sureeee
:politely nods head in a bobbling manner of disbelief:
like what putting 30 or 50 fishpaper-rings on batterys?
i dont know with what you are glueing, i do this in a few minutes with my gun.
everything is already set up, its more like a plug n play style thing
if you know how to route correctly, this will not consume time, what are you doing, drawing a map for cables?
soldering like what? 10 cables? how does this take long.
sticking tape on things? well, i forgot this take ages…
a “quality” pack should use ready cables, since crimping JST is a pain in the ass
putting the full pack in a memory polymer and then add heat with a hot air gun? yes indeed this needs hoursssss
if youre using tungsten tin and need to heat up the thing to 3000-fuckme degree, it will take some time, yes
totally forgot to count the time i have to stare at the pack while it is charging and accurately measure the temperature every 10 seconds for my excel sheet.
Go build a friggin pack and stop talking about it then. Simple.
Since your the fucking battery pack hero, and everything magically assembles itself, take a video for all to watch your master skills, and let everyone else be the judge.
Even more so yea I said 10-14 hours for FLEX packs. If you plan to isolate everything properly. And I’m not a believer in stiff packs that go the length of the board. I build inside of the smallest thickness enclosure I can, every board has flex. If your battery is sandwhiched on the deck and you build a stiff pack, your eventually gonna have ripped welds.
So sure take your 4hour stiff pack build. Everything I mentioned was to notate that it took time and added up. Not to say it takes forever.
But yes if your building a flex pack it takes fucking forever. Your basically building individual groups, all taped and wrapped individually and connected.
