At this moment I''m building a charger for Li-ion battery based on constant current, constant voltage method. I have used IC LT3741 to build a charger. The specs of my charger: 8,4 V, 2A. But I dont understand one thing: When charging the battery, the voltage of battery will be lower than the output voltage of the charger (but of course greater
can i power a device with more output amperage than the device
Voltage is pushed to the device from the power supply, so an excessive voltage can easily damage the device. Current is pulled from the supply by the device, so the device only draws the current that it requires, regardless of the maximum current the
Lower the Volts, higher the Amps, and vice versa?
"the lower the Volts, the higher the Amps" is what applies when you alter the load to consume the same power on a new voltage. Here, the constant (as a desired result) is
Will A Higher KV Motor Use More Battery Than A Lower KV
To achieve the same power output as the higher KV motor, it would draw more current but at a lower voltage. It tends to be more efficient at lower speeds because it''s operating closer to its
Motor selection for battery-powered industrial
A motor''s efficiency directly affects the rate at which a battery is drained; the more efficiently a motor operates, the less power it draws from the battery, subsequently extending battery life.
Can a Bad Battery Cause Reduced Engine Power?
Anything significantly lower may indicate a problem. Keep in mind that a battery''s voltage can drop when it''s under load, so it''s essential to measure it when the vehicle is not running. increase the longevity of your vehicle''s battery and reduce the likelihood of experiencing reduced engine power due to battery problems.

Is it okay to power a DC motor at a higher voltage than it is rated
There are two independent limiting factors here: max RPM and overheating. The no load RPM of the motor will be roughly proportional to the voltage, and you can almost certainly get away
Is it safe to use a lower wattage powersupply
It is not a good idea to use a lower than recommended power supply. However, it can be safe under certain conditions: - The current on the 12V rail is more than what the GPU and CPU combined require. I wouldn''t use anything under 24 amps here. - It is a quality PSU, with at least an 80plus Bronze rating.
Power consumption when DC motor runs on battery
So I have to choose a 12V, 3A = 12 * 3= 36W power supply to run the motor.This is because DC power supply can supply continous 3A current without any disturbance. Now I wanted to run same motor on battery. I would like to know how much power should be supplied by the battery to run the motor theoretically.
Does using a lower wattage power adapter for a MacBook
The CPU will thermal throttle, sure, but not all components can thermal throttle. For example, the battery''s longevity will be reduced due to excessive heat fact, I got into fan curve tuning because Apple''s default fan control favours silence over cooling (running a 13" MacBook with a 4k display over usb-c pushed the battery to 43 Celsius on idle load).
Relationship between Battery Voltage and Motor Speed
Yes! RPM is generally fairly linear with voltage increase or decrease. A lower voltage will give you less speed and overall less power. SetVelocity uses the motor''s internal encoder as a speed

Designers should remember this ratio in future BLDC design of drivers. Thus if so, the coil absorbs the power and with no air flow may be safe. Since fan load increases
batteries
$begingroup$ Car battery will work but have a relatively short lifetime. Car batteries are designed for "float " operation = being kept near full charge most of the time. If you want to regularly discharge a battery by a substantial % of its total capacity you need a "deep discharge" battery if you want reasonable cycle life.
Using a higher C rating lipo than recommended
If you start drawing more power than your 20C battery can supply, it will chemically damage itself trying to supply the power leading to swelling, heating and a shortened life. If you overprop a 10 Amp motor, power it with a 20C battery and draw 20 Amps, the motor may flame-out but the battery will be OK. Nov 01, 2010, 02:38 PM #13
Key Considerations for Battery Powered Motors
Battery powered motor applications require careful design considerations to pair motor performance and power consumption profiles in concert with the correct battery type.
Can someone explain power tools to me? : r/engineering
Theoretically, you can get any amount of power from an 18V battery. The power is volts x amps, so if the motor draws lots of amps, it will have lots of power. However, if you want lots of power, it''s practical to use a higher voltage, so you don'' have to use high current. That''s why a high power tool will run on 240V, rather than 120V.
Lower power output when charging devices, is that ok?
@MaQleod, alright, lets see if i get this correct, so, if the device is charged with a lower amperage charger, it will charge slower, and if the charger is able to negotiate the power use, it is able to regulate the rate of the power the device is trying to pull, else, the device might try to pull power faster than the charger is able to supply which has the possibility of causing damage if
Is Higher CCA Always Better? Understanding the Role of Cold
This is especially true for diesel engines, which generally require more cranking power than gasoline engines. Longer Battery Life: A battery that consistently operates below its maximum capacity can potentially have a longer lifespan. If a battery is not pushed to its limits every time it starts the vehicle, it may experience less wear and

The battery AH rating should be chosen based on the motor power rating ÷ motor voltage rating x 1hr. A 48V 500W motor should be paired with a 48V battery that has an
Will A Higher KV Motor Use More Battery Than A Lower KV Motor?
Lower KV Motor: A lower KV motor spins slower at the same voltage. To achieve the same power output as the higher KV motor, it would draw more current but at a lower voltage. It tends to be more efficient at lower speeds because it''s operating closer to its optimal RPM range and doesn''t need as much electronic control to reduce its speed.
Whats the criteria for selecting a battery based on motor and
The battery AH rating should be chosen based on the motor power rating ÷ motor voltage rating x 1hr. A 48V 500W motor should be paired with a 48V battery that has an AH rating of at least 500W ÷ 48V x 1hr = 10.4AH. This helps assure that the battery will not be over stressed when driving the motor at max power.
Can a BMS''s current rating be lower than what your battery can
I recently built a battery for a golden motor black pie v5 that has 25a controller built in. I have a 35a bms but I used Samsung 30q''s that are capable of 15a output each. BMSes typically use power MOSFETs with very low Rdson - there are limits to the MOSFETS current capacity - in addition, the small RDSon (say 0.04 ohms) is still going
6 FAQs about [Is it OK if the battery power is lower than the motor power ]
Why do motors turn slower if voltage is low?
The reduced voltage causes motors to turn slower. This reduces the torque handling capabilities for DC and gearmotors, whilst causing vibration motors to vibrate less. Also, some battery designs have different voltages – even though classed as, for example, AA.
How does battery voltage affect motor speed?
Batteries also see a decrease in terminal voltage as the output current (load) increases, which also negatively impacts motor speeds at higher torque loads. These factors do not consider the characteristics of the motor winding itself, where output speed decreases as the motor load increases, even with constant battery voltage (see Graph 1, below).
Why do motors reduce battery life more than normal operation?
Motors draw more current when they start (to overcome the inertia of the mass or friction in gears) than during normal operation, therefore they will reduce the battery life more than normal operation.
What happens if you use a 3V battery on a motor?
Conversely, if the motor is rated at 1.5V using a 3V battery runs the risk of immediate damage to the motor (as would anything above the Maximum Operating Voltage). The reduced voltage causes motors to turn slower. This reduces the torque handling capabilities for DC and gearmotors, whilst causing vibration motors to vibrate less.
How do you choose a battery for a motor?
An essential criteria in battery selection is making sure that the battery will not only supply the motor’s voltage and current requirements when fully charged, but also continue to meet those requirements as it approaches full discharge.
How to change battery voltage vs 40 450 motor?
Any guidance you could provide there would also be much appreciated. The battery does not have high enought voltage (3.2V battery vs 40-450 motor), so you need to change the voltage by connecting more such batteries in serie (10 and more), or using some step-up DC/DC change.
