Awesome job with disassembly, but you really shouldn't mix cells like that. This goes double for a sealed unit that's not easy to get into. The different internal resistances and overall capacity can put more strain on the charge controller, not to mention the risk of over/undercharging one of the cells if the BMS does a poor job at balancing mismatched cells. For those of you who are going to slap another cell in, take the time to check the capacity of the existing (good) cell and the replacement. A good charger like the OPUS BT-3100 will let you check the capacity of the cells so you can match them. Ideally, make sure you bring both cells to a full charge BEFORE you install them into the speaker. This just ensures they are balanced from the get-go.
Having watched this video -- showing all the details, which is really great -- I'd say this Unit is Not User Serviceable. The website for the product says that, too, I discovered later.
One last thing for those reading this... Don't just grab wire and solder it to the cells like that... You absolutely risk the wire heating up and causing issues down the road. If you do use wire instead of the nickel plates normally used, then make sure you always use the same gauge (AWG), or larger, as the wires connecting to the battery. Do yourself a favor too and get decent cells from LGChem or Sony. The HG2 and VTC5 (or VTC6) are excellent cells for the purpose of a battery bank/speaker and have fairly high charge/discharge cycles before they lose capacity.
My speakers top panel has caved in,the buttons section is now got holes so need a replacement cabinet or atleast the top section, Anker India does not support this product anymore, can anyone help😢
@@melas75magarang I already did , they asked me for invoice copy which I sent as well, after which they flatly declined any help saying product is out of warranty even though I was ok to pay for the replacement panel.
Thanks, i managed to replace the batteries with 2x18650 3.7V. They are the same as those used in my Laser 301 ! Only, the soldering was troublesome. I'm not used too. but i got it done. Now, my Anker hold the charge for a very long time... more, than 10 minutes the dead's one.
I am facing a big problem.1. Speaker goes off ,if not Power plugged.Please tell a genuine solution.Also I have noticed when bass boost mode is on,maximum time speake switches off.
Have issues with the speakers, they're crackling and cutting out the speakers. Tried Google but no joy. Anyone know if they're available before I rip mine apart?
Hi! My Soundcore Motion Boom has a problem that it suddenly powered off automatically within 20secs everytime I turn it on. Sound control and bluetooth still function. Could you guess which part might be failed? Now I have already torn it down…
Hello I have the same problem with my motion boom. sorry for posting it here, but even when I put the speaker on a direct power supply (without batteries) it turns off after exact 15 seconds. is it a "safety feature"? can you guess whats wrong?
Hi brother, I have replaced the battery but the speaker only turns on when the charger is plugged in and also there is no voltage for charging batteries in the circuit. Can u help pls ?
Hi! I ordered a battery, my concern is that every official battery replacement part is 7.4 Volts. Is it safe to replace the 7.4V battery with the 3.7V used in the video?
@@melas75magarang I see, it's two batteries in one case, although it came with a 2S pin connector as opposed to the 3S shown in the video. Would you recommend changing it to 3s pin?
@@melas75magarangThe speakers connection is s3 or s4 I think, so can't use the s2. My plan is to recycle the connector from the old batteries, and use the with the new one.
@@melas75magarang Right, but by doing so you expose yourself to a little explosion and on top of that you shorten the life of the battery... There is a reason soldering on Li Ion is prohibited... But hey, do as you desire and stay happy!
Todo el buen trabajo terminó en cuánto llegaste a las baterías, cambiar solo una es un trabajo mal hecho. Jamás se puede mezclar baterías nuevas con viejas y menos recargables. Yo no te llevaría ni una portátil para reparar.
Sir.i wanna ask.can i use another brand battery 18650 like mxjo 3500 mah or sony vtc6 3000 mah.it is compatible without using ncr 18650b ? Thank you sir
Yo intente reemplazar ambas baterias pero al momento de ensamblar la targetita que trae las baterías se quemo al hacer contacto con un cable que deje mal. Donde podré conseguir esa tarjeta sabrás?
Too lazy... So I'm just gonna throw it in the landfill instead of taking the initiative to fix it. This mentality is exactly why every tech giant gives zero f***s about e-waste and laughs to the bank with your money.
@@melas75magarang Just make sure when you edit the video before you upload it as some people don't notice it until it's to late I know it's pain in the arse but if you could zoom out I little bit so we all can see exactly everything then people won't be commented on your videos like I did
