Hmmmm I see, okay thanks!
This is a super noob question but I just want to make sure I understand it. If I have 2x 5s LiPo packs in series, that would be considered 10s1p, correct? And if they were in parallel, it would be 5s2p?

Yesā
this
But yes it can be done, but generally there is a certain way it must be done or it wonāt work well at all.
I see in most builds that use Li-po batteries, the packs are ~5000mAh, although looking at Li-ion batteries, the 18650, they are typically ~2500mAh.
Does that mean if you were you build a Li-ion pack, you would never do 10s1p because in series, you donāt add up the mAh, and ~2500mAh is not enough?
So you would NEED, if using Li-ion batts, have at least a 2p to get ~5000mAh (since when batteries are in parallel, you do add up the mAh)?
Li-onās last longer and typically are energy dense
Lipos are known for there power density (also energy dense due to no metal encasement)
but Li-ons are generally more reliable and last longer so I say they are more energy dense because you typically get more cycles out of them which means more energy output over its lifetime.
pick one then study it Lipos tend to be a quick and easy read
Where as Li-ons are harder to learn but in my opinion worth it.
check out the samsung Q30 18650 cells if you are going that route.
power density = peak wattage
energy density = sum of total watt output over discharge cycle.
lion 10s1p would be only 420w peak output so not power dense enough.
but 2500 / 1000 * 36v = 90wh (aprox 9kms worth of range)
You might be happy with 9km range but you wonāt be happy with traveling like a snail
thatās why lipos are good for a quick punch on a low range setup.
Why are XT90 connectors so hard to solder? XD I melted 3 pretty bad. Idk why i expected to be able to do it right off the bat, so I looked up some tutorials, but have not tried again yet, since I ran out of the last of my solder.
Has anyone used the VRUZEND for esk8 builds? I am planning on it right now, because it was a cheaper alternative, and more āfixableā Iāll say. Hoping that it will be able to deal with a 12s7p pack with two 190kv 4000kw motors.
Hoping to make a topic soon, I have a class that I need to post some research questions for!
Itās better to just pay someone to weld you up some P-groups and do the rest of the soldering yourself. Would have to go with 1/2 the size battery you want to fit the holders.
There are tutorial for soldering connectors, you just need flux and a good soldering iron. I use a 2-in-1 station that was like $80 on amazon and it rips.
@Fosterqc Iām doing a mountainboard build, and I already calculated the size based on the dimensions of the caps, and even with a 12s7p, it will fit nicely between the feet. I agree that you would not be able to get the best battery if you did it under the board, and then spot welding or soldering would be best in that situation!
I watched a few tutorials to see where I went wrong, and bought some extras incase I still mess up, I also should probably crank down the temp, that way I wont melt the connector!.
Also if anyone would be willing to help me out with a research project for college I would appreciate it!! Looking for anyoneās opinions, so I can gather some data for a class!
ohhh for a top mount MTB!!!
thatāll be fineeee
Hope to see you ripping it soon!
Funny enough Iām making two 12S7Ps at the moment. A insane 25R one for me and a 30Q one for a friend.
You love your friend more than you love yourself
FOR friendlies sake stick to the Q30s
Youāre losing 500mAh per cell and itās common knowledge that Q30s can output 20a safely.
So even if the 25Rās can output a little more that will be short lived once you get below 70% charge as by then youāll clearly be rocking something inferior.
Iām in it for the cheap power I didnāt want to pay the extra lol.
I have other batteries for range. Working on like 5 boards at the moment.
ok ok respect back in the day I remember the 25rās as same price or more even LoL
your stats are better than mine that was dumb of me (was partly miss informed)
when soldering xt90 connectors plug them in to each other so that the pins donāt move if the plastic melts a bit,
Saw that on a YouTube video! I just got some more solder, and I am going to try this, and a few tips and tricks for things I was completely doing wrong. Hopefully, Iāll have no issues and everything will go smoothly!
good i want to use this engine
like this
esc
but I have no idea which battery to choose. I plan to use a 18650 cell battery
If anyone can help me thank you !!
if you live in the usa just save yourself the pain and get motors and the upcoming TB6 esc from Torqueboards.com
to say that this engine is not good?
Sorry for my ignorance but I canāt understand this:
if an electric motor like that
that have 80 amps
can be connected to this esc
that only allows 50 amps . I can not understand if I connect a battery that provides 80 amps will not burn the esc?
