Electric car Safety The Lithium-ion battery is combustible and can catch fires, it has power cells that can cause short-circuiting if it is damaged. However, lithium-ion batteries have a much lower risk of fire explosions than gasoline in conventional vehicles. … Continue reading →

The strongest material in the universe may be the whimsically named “nuclear pasta.” You can find this substance in the crust of neutron stars. This amazing material is super-dense, and is 10 billion times harder to break than steel. What … Continue reading →

The Tsar Bomba. The Tsar Bomba is the single most physically powerful device ever deployed on Earth, the most powerful nuclear bomb tested and the largest man-made explosion in history. Which is the No 1 weapon in the world? Designs … Continue reading →

Metal armor is no longer practical. Although it had its benefits in the days of old, technology has rendered it obsolete. Metal armor is heavier and less flexible than the kevlar and ‘dragon skin” body armor used in combat and … Continue reading →

BYD. BYD (BYDDY) In 2008, Buffett’s company Berkshire Hathaway bought 225 million shares of BYD for $232 million. Berkshire’s latest shareholder letter shows it still held those shares as of Dec. 31, 2020 — except their market value had surged … Continue reading →

Duracell Plus 9V batteries are alkaline batteries ideal for powering all your devices. Duracell Plus 9V alkaline has 100% life guaranteed* (*commercial guarantee vs. the Minimum Average Duration across 2015 IEC 9V battery tests. Results may vary by device or … Continue reading →

Ebike power can be boosted by simply turning a ‘pot’ screw, disconnecting the power smoother plug or simply fitting a higher voltage battery. Alternatively, on high spec ebikes where battery and controller are inaccessible, you can fit performance chips. Can … Continue reading →

To get the right battery power for your vehicle, you need to consider the cold cranking amps (CCA) and reserve capacity (RC). Cranking amps is the measure of your battery’s starting power and should always match the standard requirements of … Continue reading →

The main advantages of LiPo battery cells are that they have about four times the energy of density of nickel cadmium or nickel metal hydride batteries. LiPo batteries are very lightweight and pliable, and can be made to almost any … Continue reading →

What voltage is required to charge it? A: A 12V car battery can be safely charged over a range of voltages. It needs at least 12.9 volts to charge, but at this voltage the charge rate of an automobile battery … Continue reading →

Whenever a battery is being charged, the terminal voltage of the battery changes a small amount whenever the battery temperature changes. As the battery temperature increases, its terminal voltage decreases or as the terminal voltage decreases, its temperature increases. Why … Continue reading →

To check the entire circuit, connect the meter positive lead to a clean spot on the starter motor case and the meter negative lead to the negative battery post. Crank the engine and note the reading. The voltage drop on … Continue reading →
