This is one of the best Poundland purchases I've made in a while, purely because of the Google trek for knowledge that it sent me on. Most of Poundland's power banks in this style come completely discharged due to the higher than usual quiescent current of the circuitry. I wanted to know if that was a serious issue or not. Here's the best documented test I found. https://www.nature.com/articles/srep30248 If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm

DIY: How to revive a dead 18650 (or any) Li-ion battery cell
 
04:37
Today I will show you how to revive a dead 18650 Li-ion cell that's being refused by the chargers. This method will work with any Li-ion battery, not just the 18650 cells. Here's my follow-up video:https://youtu.be/vFmbG8GpS4A if you wonder how much current (Amps) goes through the wire. Note: this is not a permanent way to charge an 18650 cell. The point of this method is just to bring up the voltage of the dead cell to a point that is enough for a real 18650 charger to accept it and charge it properly. When a Li-ion battery does not have high enough voltage, the charger would not charge it. I think the reason is safety because if the voltage is too low, it might take a risk of charging a NiMH or NiCad cell which are only 1.2 volts each. And if you put a NiMH or NiCad cell (at 1.2 Volts) in a Li-ion charger that charges up to 4.2 volts, all hell will break loose. Also: don't overdischarge a Li-ion cells down to below 3V especially below the threshold recognized by the charger. Otherwise, it will not live long. The "Goldilocks" zone for a long and healthy Li-ion cell life is between 30% and 90% charge. Too much charge or discharge would be bad for the cell.

Reclaimed 18650 Test Charge Discharge How To
 
10:34
Getting Started in reclaiming 18650 Lithium Ion Cells from Power Tool and Laptop battery packs is a great way to get a pile of cells. But once you do... Then what?! Here I step through the process of Testing, Charging, and then Discharging the cells to find the capacity of each cell. Hopefully this helps to demystify topics surrounding how to process recovered 18650 cells. Tools Needed: - Basic volt/Multi-meter to check the cells voltage once liberated from the packs. - Lithium Ion safe charger units like the TP-4056's - RC grade charger/discharger unit, Like the Venom ProCharger used here, or a SkyRC IMax B6 or similar.

Discharge and Charge Process of a Conventional Lithium-Ion Battery Cell
 
01:42
Discharging During the first stage of discharge lithium atoms oxidize by forming Li+ ions and electrons, whereas Li+ ions move to the positive electrode diffusing through the electrolyte and the separator. The electrons flow from the negative electrode to the positive on the external circuitry, where the resulting current flow can be used for an application. At the positive electrode the electrons recombine with the Li+ ions and are stored in the molecular structure of the active material. Charging: If an external voltage with the same polarity is applied between the current collectors, the charge process will start. The lithium atoms leave the metal oxid structure and ionize into Li+ ions under the release of an electron of each one. In analogy with the discharge process Li+ ions diffuse to the negative electrode. At the surface of the graphite particles the Li+ ions and electrons recombine with each other forming neutral lithium atoms and are reintercalated into the molecular structure of the graphite particles.

Battery Charge Vs Discharge And Why It Matters
 
03:17
Ever wonder why the state of charge matters on a battery? It is actually critically important! In this video, we will discuss what state of charge and depth of discharge are and why they are important. In short, the deeper you discharge any type of battery the more you shorten its useful life. Some batteries are better than others at this, such as lithium ion, but it still plays an important part in your strategy and planning for your off grid solar panel system or e-bike battery or whatever project you are working on.

How to recharge a fully flat lipo (lithium polymer) battery
 
05:23
WARNING: do this at your own risk, lipo batteries can rupture and cause a significant fire hazard, especially if they have been over-discharged or over-charged. As you can see in this video, it is possible to save a lipo battery that your charger refuses to charge -- so long as you are *very* careful. Remember, a battery recovered in this way should always be treated with caution afterwards but providing sufficient care is taken, a rescued battery can continue to provide many more cycles of use.

DIY: How to Revive a dead Li-ion power tool battery
 
08:15
Fix your dead battery by using a DC power source to raise its voltage. Note: do NOT use a DC power source with more voltage than the maximum rated voltage of the dead battery. If you have a regular 18V or 20V battery pack, that's 21V max (4.2V x5). Do not use a DC power source more than 21V to revive the dead 21V battery. About the wires with alligator clips: make sure you use heavy gauge wires size AWG 14 or bigger. The alligator clips with attached wires from Harbor Freight are not going to make it as the wires are too thin and they will heat up and just melt or burn the insulation right away. And make sure to monitor closely what you're doing cause it might heat up things quickly. As soon as you get the desired voltage (about 16V or more for this kind of batteries), just remove the alligator clips and put the battery in the charger. In other words, just do the parallel charging as minimal as possible and just enough for your charger to recognize the dead battery.

Want to include a small Lithium Ion or Lithium Ion Polymer battery into your next project? It's easy! Dave gives you the low down on how they work and how to charge them and select a suitable charging IC. NOTE: For safety you should always use circuit protected cells as per the larger cell I was holding up. It protects against over-discharge, over-voltage, shorts etc. (BTW, the reference to Lithium Ion Polymer being the same as Lithium Ion is in terms of charging, if that was not clear. The Ion Polymer type have polymer anode material and hence a different construction that allows the small pouch type cells shown in the video, and other thin odd shapes shown toward the end)

A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

Lithium-ion batteries: How do they work?
 
03:08
Smartphone, cordless screwdriver, laptops and defibrillators: Everyone knows the lithium-ion battery - or the Li-Ion Battery - for energy storage in a variety of modern appliances. A great future for the battery is predicted in the modern electric car. But how does this battery work? The animation shows how the components of the battery work together to release energy and to recharge the battery again. The goal: BASF wants to make the electric car of tomorrow reliable and suitable for everyday use with lithium-ion batteries. BASF helps to increase the mobility of the electric car by making the lithium-ion battery even more powerful. This film explains the principle of the lithium-ion battery: The battery is enclosed in an aluminum and copper layer. In between are a positive electrode, the cathode, and a negative electrode, the anode. The cathode consists of a lithium metal oxide, the anode is a graphite layer. In order for the Li ions to migrate into the cell, the cell is filled with an electrolyte. The electrolyte of the battery must be extremely clean. Cathode and anode in the battery are split by a separator, which is permeable to the Lithium-ion. In addition, the process of charging and discharging is displayed.

Caving Vlog #55 Short tutorial on building a 2-series, 1-parallel, 7.4V Li-ion battery for use with caving headlamps such as the Manley, Sten or Scurion. High capacity Panasonic NCR 18650B cells are used, which gives a battery with about 30% greater capacity than commonly available battery packs. Always use a PCB/PCM to protect the battery from over-charge or over-discharge, and protect you and you headlamp from short circuits. Use tabbed batteries to avoid applying heat to the batteries, which can be dangerous. Tabbed Panasonic NCR 18650B cells can be found for ~$7 ea on eBay. 7.4V PCB can be found on eBay or Amazon for ~$3-4 ea. Total cost of a 2-cell battery is ~$20. Caves are delicate and potentially dangerous places.

Li-ion Balancing and Protection Board BMS,  How it Works?
 
02:21
EV-Customs Website - http://ev-customs.com/index.php/home/ Facebook - https://goo.gl/tu3Qdk Music - Joakim Karud The Orion Battery Management System (BMS) performs three primary functions: It protects the battery pack from being over-charged (cell voltages going too high) or over-discharged (cell voltages going too low) thereby extending the life of the battery pack. It does this by constantly monitoring every cell in the battery pack and calculating exactly how much current can safely go in (source, charge) and come out (load, discharge) of the battery pack without damaging it. These calculated current limits are then sent to the source (typically a battery charger) and load (motor controller, power inverter, etc), which are responsible for respecting these limits. It calculates the State of Charge (the amount of energy remaining in the battery) by tracking how much energy goes in and out of the battery pack and by monitoring cell voltages. This value can be thought of as a fuel gauge indicating how much battery power is left in the pack. It monitors the health and safety of the battery pack by constantly checking for shorts, loose connections, breakdowns in wire insulation, and weak or defective battery cells that need to be replaced. There are also secondary functions that the BMS performs: Balances all the cells in the battery pack by intelligently bleeding off excess energy from cells that are charged more than others. This provides the maximum amount of usable energy (capacity) from the battery pack since the pack is only as strong as the weakest cell. Monitors the temperature of the battery pack and controls a battery fan to regulate the temperature of the pack. Additionally, it constantly monitors the output of the fan to make sure it is working properly. Provides real-time information and values to other devices such as motor controllers, chargers, displays and data loggers using several different methods (CANBUS, analog outputs, and digital outputs). Stores error codes and comprehensive diagnostic information to aide in fixing problems with the battery pack should any issues arise.

Lithium Ion Batteries:  Why They Explode
 
03:16
Lithium ion batteries are all around us. In our homes, our cars, even on our person at nearly all times. And so when a cell phone, laptop, or car battery explodes it can rightfully be a cause for concern. However, there’s a lot that goes into the creation of any single lithium ion cell and even a small error at a given point in that process could lead to big problems during the battery’s life cycle. Greg Less, Michigan Engineering’s Battery User Facility’s Manager discusses not only why and how the lithium ion batteries that we all use so frequently might explode, but how researchers at the University of Michigan are trying to change the way batteries are made for a safer and more efficient future. ABOUT THE PROFESSOR Greg Less is the Senior Laboratory Manager at the UMEI Battery Fabrication and Characterization User Facility, responsible for the day-to-day operation of the laboratory. Greg received a doctorate in Chemistry from the University of Michigan. Prior to joining UMEI, he was a research scientist with battery companies T/J Technologies and A123 Systems.

All About Rechargeable Lithium Ion Batteries
 
08:53
We get a ton of questions regarding batteries, so we scoured the world, did a little digging, and researched the topic. Now you'll have some real answers on battery recharging cycles, whether you'll need to unplug your device once it's fully charged or not, if you need to condition your battery to avoid the memory effect, and even some information on who and when current rechargeable batteries came into existence. Please add to the discussion if you have any REAL information - leave the old wives' tales on Kim Komando's channel. Thanks. Lithium batteries were proposed by M. S. Whittingham while working for Exxon in the 1970s. However, Whittingham’s rechargeable lithium battery was extremely expensive and smelly. In 1983, Michael Thackeray, John Goodenough, and coworkers further developed a lower-cost alternative that worked better and didn’t smell. Two years later, Akira Yoshino improved the design, enabling industrial-scale production. In 1989, Goodenough and the University of Texas at Austin figured out how to make the design even better and more powerful, and that lead to the rechargeable lithium ion batteries we use today. There is no “memory effect” as there was with older rechargeables, and battery calibration software is unnecessary nonsense. The lithium ion battery does have a few weaknesses. First, they hate extreme cold, or extreme heat. Fortunately, they work really well in temperatures that work for humans. So keep them out of the freezer and away from a hot car, and you’ll be golden. Secondly, all batteries die eventually. First, they’ll lose their capacity to hold a full charge, so you’ll notice them dying faster and requiring more plugging in. Then, they’ll refuse to charge at all. Most lithium-ion batteries have a rated lifetime of somewhere between 300 and 1,000 charge cycles. Drops and falls can damage the internal components, causing dangerous leaks, so be careful. Finally, lithium ion batteries are expensive and often not easy or nearly impossible to replace. Apple devices especially do not want you to open their devices, using gobs of Chinese glue and freakishly weird screws to make it as difficult as possible.
