A “floating” neutral occurs when the connection to the ground breaks or becomes loose, which causes the neutral bar to “float.” This can happen in your panel or between the utility and your electric panel. It can be caused by … Continue reading →

A floating power supply is a power supply that can be used with its output floating ground. While ordinary DC power supplies are used with one side of the output end grounded to the ground, floating power supplies can be … Continue reading →

China’s diversified chemical producer Do-Fluoride New Materials has signed a strategic cooperation agreement with major domestic electric vehicle (EV) and power battery manufacturer BYD to supply lithium hexafluorophosphate (LiPF6) over the next four years. Where does BYD get lithium? Chile’s … Continue reading →

This loss of capacity (aging) is irreversible. As the battery loses capacity, the length of time it will power the product (run time) decreases. Lithium-Ion batteries continue to slowly discharge (self-discharge) when not in use or while in storage. Do … Continue reading →

What makes the iPhone so unique is the operating system it runs. Unlike other smartphones that are powered by Android, the iPhone runs iOS, a proprietary operating system designed by Apple. But often counterfeit iPhones are powered by Android but … Continue reading →

How to Calculate the Battery Charging Time & Battery Charging Current – Example Required Charging Current for battery = Battery Ah x 10% Then 120 x (40 ÷ 100) = 48 …… ( 120Ah x 40% of losses) 168 ÷ … Continue reading →

You shouldn’t invest in an IPO just because the company is garnering positive attention. Extreme valuations may imply that the risk and reward of the investment is not favorable at the current price levels. Investors should keep in mind a … Continue reading →

It all starts with metals and minerals. Prized cobalt mostly comes from mines in the Democratic Republic of Congo. Nickel is largely gathered in Indonesia and the Philippines; lithium in Argentina, Australia and Chile. What are electric car batteries made … Continue reading →

This is a new type of batteries which arrived in the 1990s and replaced metallic lithium with lithium ions. Lithium-ion batteries are lighter than Ni-Cd or nickel-metal hydride batteries and can be used for longer periods. What are Panasonic batteries … Continue reading →

Wi-Fi signals operate over radio waves, which are highly sensitive to interference from metallic objects. A strategically placed metal barrier — such as one made out of tin foil — will completely reflect all the Wi-Fi signals it encounters in … Continue reading →

Starting the engine will require 250 amps for a half second, and the most current a 1.5-volt AA battery can produce is 10 amps. Given the above, you’d need to start with a string of eight AAs to get your … Continue reading →

2: The majority of the world’s known lithium resources are found in brine pools on the Pacific coast of South America. Where is lithium most commonly found? Where is lithium available from? With 8 million tons, Chile has the world’s … Continue reading →

Different Chemical Makeups A lithium-ion battery usually uses lithium cobalt dioxide (LiCoO2) or lithium manganese oxide (LiMn2O4) as the cathode. Whereas, a lithium-iron battery, or a lithium-iron-phosphate battery, is typically made with lithium iron phosphate (LiFePO4) as the cathode. Is … Continue reading →

They were made by Hongkong Sun Rise Trading Ltd. of China and sold for about $350 at Lowe’s and on Lowes.com, as well as other walk-in and online retailers, including Amazon.com, from May 2014 to July 2016. Who makes Kobalt … Continue reading →
