you said max. battery capacity usable is 80 percent. to overcome it you are multiplying it with 1.2 right? now find the 80% of multiplied value, you will get 96 which is less then we required.
solution: you must have to multiply with 1.25 to overcome 80%.
No, 1.2 is correct, let me explain you.
We need 750W if we consider 80% we will use means a 20% loss.
So 750*0.2 =150
So we need 150 extra so 750+150=900 W
@@nitin4171 if there is loss of 20%, then the figure of 750W should be divided by 80% to arrive at 100% value which is 937.5
1.25 is correct. If a battery has 80% efficiency and we need 750w after the loss in power, we need to find a battery wattage whose 80% = 750w.
80% of X = 750w
0.8 × X = 750w
X = 750w / 0.8
X = 937.5 w
937.5 w / 750 w = 1.25
750w × 1.25 = 937.5
Namaste Bai can I purchase battery pack for 250w motor ka 60v 40ah battery lagasakthi hai Kya Bai. Previous it was 60v 24ah pack. Is there any issue will face upgrade the amphs. Please reply me.

Sir 3kw & 72 volt ka motor 72volt & 45amp ki battery ke sath kitna km range de sakta hai
Can I use 1 crate battery
धन्यवाद।
Thankyou sir for giving the information.
Sir is voltage matters while charging the battery?
Voltage will be constant according to the battery max voltage while the current must be constant according to the cell C rating. Higher rate of charging current will heat up the cells and damage the battery pack.

250w ki moter h 48v30am bttry h to gadi kitna km chalengi ?
sir i have 2kw, 48v motor. i want 100km range at maximum speed of
1) 30 kmph and 2) 60 kmph.
for both case if i calculate i found that battery capacity required for
1) 30 kmph is 173 AH, and 2) 60 kmph is 87 AH.
now this means that for higher speed, battery capacity required is less whareas for lower speed, battery capacity required is high. i can't understand that how it is possible.
i mean motor placed in e rickshaw with maximum speed of 60kmph will definetly run at lower speed in traffic. so how it is possible...?
+chirag patel your premise is wrong. The calculation is based on max speed possible for the bike/car and not at what max speed you want to drive it.
48v 55ah ki battery ka price kya hoga or iski speed bdhane ke lia kya kraa
1200w-72v.26ah---top speed 55km to kitna chalega ek charge me=?
How do you get 35km to 20ah?
As per ur word 750w motor, 48v, 20ah battery, cover only 35kms. Travel by 35kmperhour speed ???

How much miledge will 12.5 ah lithium ion phosphate battery will give For noemal 20 inch cycle?????( 36 v 250 watt motor)?????????????????????????
This is for normal motor but if there are gears then range can increase or decrease substantially
Sir please send me backup calculation for 60v 24ah battery with 1000watt motor
Thanks sir ! But agar jyada current denge toh motor aur baaki parts mein kuch problem toh nahi hoga kyuki motor mein ampere rating rating bhi hoti hai ... ?
Motor ki Amp rating aur battery ki AH rating alag alag hain. Ek 30ah ya 40ah ya 60ah ki battery se ek 750w ki motor 15/16 amp hi draw karegi. Ah ka matlab hai, ek hour main kitna ampere de sakte hai. Ek 60 ah ki battery agar 15amp ki motor chalati hai to 4 hours take chala saito hai.
Motor ko over volting se damage ho sakta hai. Aur low voltage main over current draw se damage ho sakte hai.
@@ElectricScootersJammu what is the solution of over volt and low volt over current damages?
350 watt motor ==> 35km speed ==> 48V 40AH LI battery, then how many km range it will give ?
मेरे पास oreva e स्कूटर है 250 watt मोटर, जिसमे 48v24ah laidacid बैटरी है।
मै 48v30ah lifo बैटरी डालना चाहता हु, कोई प्रॉब्लम तो नही होगी, 48v40ah lifo बैटरी भी डाल सकता हु क्या, कंपनी बुकलेट में 48v24ah बैटरी ही डालने लिखा है।
Great video!!! But I cannot understand the explanation.
Could you suggest something for English speaker only?
