All the batteries have 2 characteristics : voltage and capacity . If you multiply these 2 numbers

you will get the total amount of energy stored in the battery : Like let's say : 24v x 20

amps = 480 wh . Now this total amount of energy will be distributed gradualy by the controler

and you will get a range accordingly . So if you use a constant and continuesly 120

w for one trip , your battery will last 4 hour per one full charge . But remember that

using just 120 w will not make you feel a big difference on the roads .You got to use

250 w or morein order to pedal easy and feel confortable on your ride . As I showed in

a previous video , E bikes have different levels of pedal assist : Like : eco ,low , medium

and high ! and behind these words the controler will take different amountof wh from the battery

to assist you . Now that i made this point clear , let's take a look at the voltage aspect

. We find in general 3 main tipes of voltage on an e-bike : 24 , 36 and 48 v which in real

life will reflect on how powerfull your e-bike will be . So an e-bike set-up with 48v configuration

will accelerate faster and climb hills easier compared to a 24 or 36 v configuration . If

I give amps to these 3 batteries , let's say : 20 , 15 and 10 the bike set-up with 48 v

will still accelerate faster than the other 2 even though it has less amps . Now if you

notice these 2 batteries have the same amount of Wh which meens that in theory you will

be able to travel the same distance with both batteries . But yet the difference is that

with 48 v you will travel faster and the battery will discharge quicker compared to 24 v which

is build for slow rides , therefore lasting longer due to it's 20 amps capacity . At the

end I made an ilustration to help you answer the question : How long does an e-bike battery

last ? . Imagine that the battery is a bottle with water turned upside down and the water

starts pooring . in this case , the wh is the total amount of water , th voltage is

how much water comes out or the size of the top of the bottle and the amperage is the

time necessary until the water poors out completely . So if you wanna get higher voltage , than

you will need a larger top of the bottle which will result in the bottle getting empty quicker

.Therefore if you wanna add more watter to increase the amps the voltage will probabily

stay the same unless you want to upgrade them as well but you will deffinately get a higher

range for the ebike once you put more water in the bottle . All right guys, that was it

! Thanks for watching , I hope you understood what I explained here , subscribe and stay
