Hello friends!
I use these type of cells in many projects, so today I will test them, because I received a few comments that they are not very good.
So let's see how bad, or good these cells really are.
A big THANK YOU to all my patrons, especially to: Max Rice, techge and Anthony Ortenzi.

Good job Sorin! All details taken into consideration, well presented, all angles covered....professional! May I suggest presenting/testing/comparing small solar panels (5-10-15 Watt) and batteries (lead-acid vs. Li-ion for example) to see which ones will perform better, last longer, cost less. Small solar panels because they cost less but we can still get an idea for scale-up. Also get Arduino into your projects. Cheers and keep up the good work Maestro!

you should get a liitokala lii 600 charger then you will be able to monitor the ohm resistance of each cell the only true way check the condition of cells as measuring the resistance of a lithium cell is difficult

Milliohm measurements on slot chargers are very inaccurate. Most manufacturers use AC impedance instead of DC IR. DC IR can be calculated manually. I would skip the Li-600 or 500S. Garbage chargers with a flawed discharge circuit design

I owned a few of these, used individually in serveral household things like my toothbrush. Honestly it feels like you got very lucky! The fake HG2's i got went bad after a year, dropping below 2 volts after normal use - not even forced discharging at high amperage. So it looks like a roulette and you got lucky. Maybe the liitokala sticker actually indicates genuine LG cells, mine did not come with that. Wouldn't recommend!

Cell temp and voltage drop are definitely the best ways to identify fakes. It would have helped if you put a voltmeter directly on the battery so you don’t have the current interfering with the voltage reading. To see the capacity dip by 25% is usually the max you’ll see power cells dip when discharged at their highest rate so I’m going to say it’s a 3000mah 10A cell, possibly a 2900mah 8A cell. Real MJ1’s are $5 each at 3500mah and 10A. Samsung 40T’s are $4 right now. If you’re in the US, 18650BS, Li Ion Wholesale, IMR, and Bulk Battery will have deals that pretty much come verrrry close to matching the Aliexpress mystery cells. If you don’t live in the US and LK is consistently sending out a 2900/3000mah 8-10A cell at $2.47 then I’d probably use those for anything except a personal electric vehicle like a scooter or bike. Unknown cycle life, unknown if safeties like PTC are present, unknown if QC exists at the factory makes it a bit too sketchy to put in a large pack. My guess would be a 2A charge and 6A discharge would bring those cells to the EOL metric within 100-125 cycles. A more gentle 1A charge and 2A discharge with 5A bursts every 60 seconds for 3 seconds would likely yield a more typical 400 cycles

what is the lowest voltage and highest temperature for any type of li-ion cells regardless of the brand or type that's safe and won't damage the cells?
@neutronpcxt372
@neutronpcxt372 Жыл бұрын
During charging, the highest temperature depends on how fast you want to charge. The higher the charge rate, the higher the temperature you want due to lower internal resistance and to prevent lithium plating. The lower the charge rate, the lower temperature you can charge at. All in all, at low to moderate charge rates, you want to charge at 25-30C optimally speaking, and the slower the charge(down to 0.2C), the better the cycle life. If possible, never charge below 0-5 degrees C. During discharging, the optimal temperature would have to be between 25-35C to extract the most capacity while retaining good cycle life at most discharge rates. Lower temps will allow you not to draw as much capacity, while high temps will cause your cells to usually degrade more. As for charging voltage: never exceed the max charging voltage specified by the manufacturer. For NMC/NCA/LCO cells, that would be 4.2V unless otherwise specified. For LFP cells, that would be 3.65V. Now, charging at lower voltages can boost cycle life, but that's outside the scope of this discussion. For discharging voltage, for NMC/NCA/LCO cells, that would be around 2.5-2.8V. For better cycle life at an almost negligible capacity loss, 2.8V for high loads and 3.0V for low loads would be your best bet. For LFP cells, down to 2.5V is fine, and 2.0V for very high discharge rates.

These Fakes can support 10A - Ok, maximum 15A - But they overheat and drop in voltage (You need to use them in parallel). People in comments saying they are not fakes - They are, they have different color wrap than original (Original is "Darker chocolate" color), also differrent top tabs. Original also have slightly higher mAh capacity and different metal body.
@ericklein5097
@ericklein5097 Жыл бұрын
No way these cells will support 15A. The capacity dipping to 2200’ish is a 25% drop from their original capacity. That is typically what you would see when a cell is discharged at it’s rated max current. Everything past that is a very steep drop with temperatures rising to dangerous levels well before the discharge is complete

Salut,din păcate este destul de dificil de găsit ceva cât de cât de calitate.Am cumpărat în ultimii 2-3 ani câteva zeci de HG2 de la diferiți vânzători de pe Aliexpress.Capacitățile celulelor variau între 2700 și 3100 mAh.Dar cel mai curios lucru se întâmplă cu ultimul lot de 20 de bucăți cumpărat astă vară.Le încarc "full", le las la păstrare și după o lună,două au tensiunea 3,2 volți.Nici nu știu ce să mai cred!Mai acum 5 ani,când m-am apucat de modificat acumulatori de bormașini,cumpăram celule "Samsung 30Q" de la un magazin de țigări electronice.Problema e că au niște prețuri cam pipărate.
@ericklein5097
@ericklein5097 Жыл бұрын
30Q’s are notoriously problematic cells that have a problem with self discharge. The only way to determine if your cells are real or fake is to discharge at their max current while recording the temperature. Then overlay your graphs with discharge graphs from the manufacturer. They should be very similar and ending temperature will be within 1 or 2 degrees Celsius. Anything outside of that or a discharge graph that looks like two different lines at any point in the curve, you got fake cells. Or severely degraded cells.

Hi. it will work, but it depends if the cells are new or used and if they have the same real capacity. if the cells are old, you should dismantle the battery packs, test all the cells and use only the good cells in a single and bigger battery pack.

Salut. Celulele de laptop nu sunt pentru curent mare de incarcare/descarcare, de asta se incalzesc. Trebuie sa cauti specificatiile modelului de celula, sa vezi ce rata de incarcare/descarcare e recomandata. sa zicem maxim 1C si recomandat 0.5C. Apoi trebuie sa testezi celulele, sa vezi ce capacitate reala mai au, sa zicem 2000mAh. In cazul acesta curentul de incarcare recomandat este de 2000mAh * 0.5C = 1000mA. Daca incarci/descarci celulele cu mai mult de 1A, se vor incinge.

I know this is an old video so I apologize, but I cant find any Liitokala brand HG2 on aliexpress that doesn't come bundled with a charger which start at around $30 for a charger and 4 cells (at the time of this post) That price is close to high end 18650 or even 21700 cells with much faster shipping times. I love your videos, but sadly long gone are the days of getting cheap 18650s on aliexpress...there are tons of cheap ones on there including ones with HG2 wraps, but out of the 20+ I have bought all measured between 1200 - 1800mah...most were in the 1200s
