Lead acid batteries have a nominal voltage of 2V/cell, whereas lithium battery cells have a nominal voltage of 3.2V. Therefore, to achieve a 12V battery you’ll typically have four cells connected in a series. This will make the nominal voltage … Continue reading →

A: As chemistries and voltage vary across both battery types and brands, we recommend that you do not mix batteries. Mixing of cells can result in battery leakage and sub-optimal device performance. Can you charge different rechargeable batteries together? No. … Continue reading →

The color change is easily visible to the naked eye. The color change happens because the heat of the flame excites the electron in the metal and they emit visible light. Flames of the color orange, blue, yellow are very … Continue reading →

In a recent development, researchers at University of California, Irvine, have developed a new nanowire-based battery material that could last forever and can be recharged hundreds of thousands of times. How do you make a battery that never dies? The … Continue reading →

Eight surround cameras provide 360 degrees of visibility around the car at up to 250 meters of range. Twelve updated ultrasonic sensors complement this vision, allowing for detection of both hard and soft objects at nearly twice the distance of … Continue reading →

The Victron Inverter/Charger internal inverter consists of a low frequency super robust toroid transformer for exceptional reliability and massive surge power capability to start such difficult loads such as fridges, air conditioners and pumps! Are Victron inverters worth the money? … Continue reading →

4.0 out of 5 starsGood performing batteries for the money. These batteries are very heavy but seem to perform well. On my first solar experience I went with these batteries after many hours of comparing price performance and other reviewers … Continue reading →

China. Given Canadian Solar’s name that may seem strange, but the rule of thumb is if a solar panel manufacturer’s name makes you think their panels are made in a country that isn’t China, then they are made in China. … Continue reading →

As you can see, Chinese brands dominate the list of best value solar panel brands. Each of these companies is large and has established a reputation for excellent manufacturing quality. How long do Chinese solar panels last? In comparison, Chinese … Continue reading →

Naturally occurring lithium (3Li) is composed of two stable isotopes, lithium-6 and lithium-7, with the latter being far more abundant on Earth. Both of the natural isotopes have an unexpectedly low nuclear binding energy per nucleon (5332. 3312(3) MeV for … Continue reading →

The fact that the moon probe Surveyor V1 revealed the existence of an appreciable amount of carbon on the surface of the moon, in the neighbourhood of its site, lends strong support to a conjecture I made in 1965 (Optima … Continue reading →

2C. The C Rate charge or discharge time changes in relation to the rating. 1C is equal to 60 minutes, 0.5C to 120 minutes and a 2C rating is equal to 30 minutes. The formula is simple. What is the … Continue reading →
