What component makes a loud POP when it fails?
Yeah, that's right 🙂

I find this feature has been integrated in many product manufactured in the PRC. Hence my “solar shed” and not controllers, inverter or batteries in house ! It’s really not complicated as my insurance might opt out !
guess? capister
very funny
Before I listen, I will guess a diode or cap blew. I think I would have replaced all of the 10v caps with 16v; maybe. Depends on what it is connected to but it would be more safer option if it is on a 12v line.
Looks aufly dry Electrolytic cap, and being 10v on 12v line? suprised it didnt pop sooner, n the fluf is likely a type of wax/other insulating 'paper'…disposable product they expect to die, could likely upgrade it n have it work better 🙂
I bet you just put that 10v cap in that just to make a video your running out of ideas mate
I have an Opus BT-C3400 that had underrated electrolytic caps too. I caught them just before they blew out because it was making a funky smell and behaving strangely.
I have the habit of thoroughly check ANY chinese "tech" BEFORE I even connect it. Often times there are solder blobs, shorts, "tombstones", missing ground connections, anonymous ICs with malware, you name it…
I think: – 1. Wick is no good without flux. 2. Solder sucker is only really ok for through hole components. 3. Wick is no good for through-hole components that are still mounted. Wick is ok for holes containing only solder once the through-hole part is removed. Wick is ok for smd pads. what ever works is ok, i guess.
Not going to spam with company names in a comment – but there are huge differences in function between brands of solder braid…should also note that it's helpful to size the wick (width, thickness) to the problem at hand.
Good job!
So many test points because 10% of this blob chips are wrong in production.
Thanks for the tip. You've made me check. I've got a bulging 10V cap in mine! We both had units from early production runs. It is a BT-C100. They are hard to find now. It's my favorite charger tho I do like my Liitokala Lii-S2. If you ever put a cell in the BT-C100 backwards I believe it is the small coil on the top of the board that smokes. Mine no longer properly terminates LiFePO4 cells so watch out or that. Perhaps the bad capacitor has something to do with that issue. It stops charging way too early- better than too late. I will replace the cap and give it another chance with LiFePO4 cells. It does charge Ni chemistries perfectly even tho the settings makes no mention of that feature.
Just checked the compatibility list, and the 21700 isn't on it, so perhaps it overloaded the charger?
