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.
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!
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.
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!
Iāve been riding an ownboard mini KT for about a year and not ready to build my own yet but wanna get something I can upgrade to increase top speed at the expense of some torque. Iām thinking the M1 then swap to 100mm boas. If theyāre too big I might resin print a custom wheel pulley with less teeth.
