48v20a battery, with what power controller and motor is more appropriate? Can it be equipped with 800W motor and controller? What will be the consequences? About the battery and motor, controller collocation, the more detailed the better, I want to assemble the car, to take into account the distance and power


A 500W motor and controller are more suitable. An 800W motor and controller are also available, that is, the load is heavy. Because 800 / 48 = 16.7 (a), it is very close to the maximum discharge capacity of 20a battery, mainly because the battery power can not meet the requirements of long distance. It can be roughly known as follows: 20A / 16.7A = 1.2 (hours), that is



What kind of power electrical appliances can a 24 V battery 80ah supply


Generally, it is calculated like this, such as 60W load, 12V system. You need to see how to use the general 60 / 12 = 5A (system current), daily use time 5A * 8h = 40ah



How much power can 21 12V batteries produce when they are inverted into a voltage of 220V?


How many ampere hours is the current of each battery?
If it is 1A / piece, the total power of the battery is 1 * 21 * 12 = 252w
In general, the conversion efficiency of the inverter is about 86%, and the power of AC220 V terminal is 217 W, that is, the maximum output is 1a (RMS)



When two resistors marked 100 ohm. 4W and 100 ohm. 25W are connected in series, the maximum allowable voltage is 40V. Right or wrong? Why?


Let's look at the current of the two. The first allowed current is 0.2A, and the second is 0.5A. Therefore, when the two are in series, take the one with small current, that is, 0.2A. At this time, the voltage is 0.2 * 200 = 40V,
bye!
