Connecting a battery in parallel is when you connect two or more batteries together to increase the amp-hour capacity, with a parallel battery connection the capacity will increase, however the battery voltage will remain the same. Does parallel increase voltage? … Continue reading →

The process involves replacing the voltage source V in series with a resistor R with an equivalent network which has a current source I=VR I = V R in parallel with a resistor R. The current source is oriented such … Continue reading →

How do you make a dc/dc converter circuit? Once the initial specs of a DC-DC design are selected (e.g., input voltage range, output voltage, output current), the first step is to select a converter IC. The desired DC-DC topology will … Continue reading →

What is Parallel Charging? Parallel charging allows you to charge more than one battery pack at the same time. The battery packs MUST be the same cell count or voltage for parallel charging to work. The big advantage of parallel … Continue reading →

A standard AA battery will contain between 1.5 and 3 amp-hours. However, some brands will offer larger versions with more amp-hour capacity (upwards of 5 or 6). A AA battery can have anywhere from 1.5 – 3.6 amp-hours of energy … Continue reading →

How do I remove the battery from my Surface Pro 4 pen? Surface Pen with single button on flat edge Turn the cap (the eraser end) counter-clockwise until you hear and feel it click into place (about 30 degrees). Gently … Continue reading →

Tesla is changing the battery chemistry it uses in all its standard-range electric vehicles to a version with a lithium-iron-phosphate (LFP) cathode, the automaker said Wednesday in its third-quarter investor deck. Do Teslas have different battery sizes? The battery size … Continue reading →

According to the EIA, in 2017, the average annual electricity consumption for a U.S. residential home customer was 10,399 kilowatt hours (kWh), an average of 867 kWh per month. That means the average household electricity consumption kWh per day is … Continue reading →

For example, a typical AA battery will stop working after 240 minutes of use powering a remote control, 95 minutes powering portable speakers, or just 38 minutes powering an RC toy. How long do AA batteries last unused? Most unused … Continue reading →

A healthy 12 volt battery should maintain a voltage range from 9.6 – 10.5 volts under the load for a good 30 seconds straight. How Much Should battery voltage drop under load? A good battery will sit around 12.6 to … Continue reading →

When looking at a BMS, they are rated for the amount of amperage they can handle. So a 4S/100A BMS will handle a maximum of 100A @ X voltage, be it 12,24 or higher. How many amps should my BMS … Continue reading →

The explanations here are that; Current equals Power divided by Voltage (I=P/V), Power equals Current times Voltage (P=VxI), and Voltage equals Power divided by Current (V=P/I). How do you calculate power? Power is equal to work divided by time. In … Continue reading →
