- new Xiamo lapel mic usually sounds great but on this video its terrible, will try something else soon. Since i have 2 pcs, maby the one in the charging case is recording the audio and the one on my lapel is just resting?
Wow the guy under me very uneducated in batteries this man knows what he doing ..he has been messing with batteries for YEARS
This is a common problem with LG cells, some of them start to self-discharge. You can balance them again, but that will be for a short period of time, you can't regenerate cells that start losing voltage, it will continue to do so even if it's just sitting on the desk. When we have some series cell licking voltage, then we will have cells in series which will be over charged every time. Overall, battery Doctor shows a common problem that requests changing all cells, and if we change all cells, there is a small cost in replacing BMS just to be safer. Late, you can use old cells for whatever you want in your life, we always return old cell or if you send confirmation on paper we can recycle for small amount of your money.
Which LG have you seen this on? Whats your shop called? We have mostlly seen it on M26 and MH1. Have you also seen zombies celles? LG cells with negative voltage, somtimes down to -40V or so?
@@TheBatteryDoctor With MH1 , ME1 , M29 but we didnt see problem with MJ1 and M26 . Usually, we blame the customer for leaving the charger connected to the battery but not plugged into the power outlet. The charger starts licking the current from the battery, and BMS can't detect it because it is too low a current. Also, the customer had a bad controller on a bike with a bad capacitor, and when they left it on the bike in winter, the bad capacitor leaked current and discharged random cells. Later, after many problems with the same battery pack, we realized it was a problem with the LG cell, this problem we didn't experience with Samsung and Sanyo Panasonic. Still, when we manufacture battery packs with our Daly or JBD BMS, and we explain to customers how to use we don't see this problem, also, we use 0.15x8 nickel-plated steel. LG cell with negative voltage only see when customer use power supply to charge battery. Our store/service is Svet Baterija doo Serbia , and we are not regular store only do business for people who understand what they buying and have respect for our product. I hope that our paths will cross in one of the next years. From Mart we will start welding with laser, finally :)
Daca te dai doktor in baterii trebuia sa si demonstrezi macar ce capacitati au pachetele(aveam rabdarea necesara dupa care sa le evaluezi)
Goana ta dupa vizualizari din păcate e mai important si de asta tine doar cateva minute😢
You don't see the bigger picture, playing with this pack is not important for anyone. Battery Doctor shows a common problem that you need to understand. If you want to play with this pack or similar, you need to unwed all cells, balance them all on the same voltage, measure all internal resistance, sort by internal resistance, left them for two weeks to see what cells have licking voltage, and then use one that has no change in voltage with same internal resistance for next project. Don't be ignorant learn the rules be safe and take your time slow.
I just bought a used Tesla pack. What do you think about them long-term?
They should be Panasonic NCR chemistry, they have excellent cycle life and can last 15 years, many are sold as "tesla 21700" in china and usually have 90% capacity.
manufacturer has used cells with 6A discharge rating and 60A BMS - but the controllers on the Scooter are 2x45A phase amp - with peak power of 6400W which equals to 88A with that 72V battery. there's your problem solved!
Zero 11X uses 2X1600W controller according to the customer, but there might be more powerful version. Looks like the controllers are actually 45A but that might be peak values? Seems to Kyesang QS-C72-17626.
Do it yourself modifications to lithium batteries should be banned in law. Can you imagine someone copying this procedure who lives in a block of flats and make a short circuit. Fire risks from these battery packs are a real risk to life.
people that are replacing batteries for vape are more dangerous then the ones building battery packs for scooters
