Hi man, I would like to know how many Ampere is the continuous discharge current of this battery. I have a 2000w engine and I heard that I need at least 42A of continuous discharge current to use all the power of the engine.
@@galacticgamer1752 I’ve got mine up and running. It’s top speed is 11mph with me and my 5yr old in it. It acceleration is pretty awesome so I’m sure with a different sprocket it would support more top speed. Only issue was the lack of hood wiring diagram and how touchy the go petal is from a stop.
I don’t understand the 72 v and 12 Ah. Can someone please explain this to me? If you did 5 in parallel, would it have 15 Ah? How many batteries would I have to connect in what way to get 60 volts? Why is he connecting the positive ends with the negative ends? I don’t have much knowledge with batteries and it would be greatly appreciated.
There are two ways to connect two cells/batteries together. Parallel: here you connect the plus poles together and the minus poles. If you do this the voltage remains the same, one cell has 3.7 two parralel cells also have 3.7V. But what changes is the capacity, as the two cells share the load they need to work half as much thus have double the capacity 3Ah + 3 Ah. Series: here you connect the plus to the minus of the other cell. The resulting larger “battery” has double the voltage. 3.7+3.7=7.2V. You can imagine if you connect one pump to the intake of another pump you get double the pressure as they both add their strength together. But both batteries have the full load so the capacity remains. Hope this helps For a desired Voltage just calculate 60V/3.7V to get a rough number of cells needed in series
@@bootlegengineer Thank you so much. This really helps and will be really useful. Thank you for taking your time to help me when you didn't need to. Just to make sure I'm understanding this correctly, you connected 4 in parallel to increase the capacity, and then connected those in series to increase the power?
Thats the gist of it yeah. Theres one thing that i might need to add. If we think about batteries like pumps that pump electrons around (and this analogy works well for pretty much everything) then the Voltage describes how much Energy/Potential resides in one electron, so to know exactly how much Power we have running we would also need to know how much current flows. Current I(measured in Amperes) denotes how many electrons are passing per seconds. So if we multiply the Energy of one electron (the Voltage) with how many Electrons are passing per second, we get the real Power thats delivered. Why is this important here? If we look at the specs of one cell. It has a limit of 10A for one cell. But if we now connect two cells in parallel each of those can pump 10A so the max Current also adds up to 20A. If we connect them in Series, one electron has to flow trough both of these so at 10A both see this whole flow. Hope this didn’t confuse but i think it was important to fully understand
I use a CV CC (constant voltage / constant current) charger that is meant to recharge ebike batteries. You just have to check if the voltages match, and the batteries can handle the current. Mine is 71.4V 4A which matches my setup. Was 45ish $
where did you get these parts because im currently looking for a 40v motor and I checked on aliexpress and they don't have anything that looks legit.

Do you ever get this up and running? I just ordered the same style motor and was wondering if it was powerful enough for a go cart?
im sure by now you have the motor. Im looking at ordering it as well. Hows the performance?

@@ktga67ishi have the same motor and i fiddled with the sprocket size and i hit 30mph on mine.
@@SKITYSTUDIOSWhere did you get the sprocket from?
@@ktga67ish i changed the sprocket on my axle i got a 65 tooth. It was on ebay.

are you still working on this project (this looks so cool)
and do you have a parts list?
What do you use to recharge the battery ?

How many watts is the motor?
What model did you buy??
Needs more dubstep and raids: shadow legends 5/10
Where you buy these parts
I pretty much get everything of AliExpress, for electronics there really aint a better place where you can get that price value.
yes
Okay
