# Best way to connect 4 Lipo Batteries together?

Hi all,

I am making a budget build so I am using Lipo batteries, I have my eyes on these 4500mAh 3s 40c Lipo Packs that give a voltage of 11.1V, I plan to buy 4 of them to get 44.4 volts and to use my VESC to set a voltage limit of 36V, Would using 3x Y connectors to connect the packs be suitable or just dangerous?

you need 4 series connectors. also, your vesc will not limit voltage. it can only take what itâ€™s given by the battery. in your case, 50.2v full, 44.4v nominal and 38.4v empty. you can set voltage limits on the esc, but if itâ€™s below the battery voltage it simply wonâ€™t work

is there a 4 series connector out there?

What do you mean if its below the battery voltage? The motors i have are 600w and the site says they take between 24 to 36 volts, I was planning to set the max voltage to 36 on the VESC, and look at tutorials for setting up the rest.

buddy please. you have 2 hrs read time. this isnâ€™t enough for what youâ€™re doing. 44v dc is very dangerous. you will hurt yourself if you donâ€™t know what youâ€™re doing

If you set the esc voltage limit to lower than what the battery is, it wonâ€™t work. the voltage isnâ€™t whatâ€™s going out of the vesc, itâ€™s whatâ€™s going in.

where would the 4th adaptor go?

Ok, so I need to get a battery or a set up that is under or exactly 36V?

Here is an example of a series harness for 4 lipos in series. The diagram you drew made no sense as the battery pack as two negative terminals instead of a positive and a negative

you cannot get a battery that is â€śexactly under 36vâ€ť. thatâ€™s not how batterys work. if you donâ€™t know this please donâ€™t build a battery

thatâ€™s a bit rough, everyone has to start somewhere.

this is a good place to start.

then watch videos, read some more.

then go build!

i dont think im being rough. he needs to know the very basics of electronics before he hurts himself

Who says Im building a battery? I was gonna simply connect packs together but now im using different ones that sit in the middle of the voltage range

Thanks Ill check them out
