bro…
my pack only has 25a cont. and I go up massive hills all the time without an issue. what are you smoking?

@DexterEsk8 I’m gonna lay it all out for ya.
If you go with that battery (x2) You have 2 choices
Choice One You set up the battery in a parallel configuration. Therefore you have a 6s config. Okay. That’s all fine. Only issue is, you have a theoretical max speed of ~19.5mph. Realistically you’re looking @ around 16mph. Not so great.
Choice Two You set up the battery in a series configuration. Therefore will have a 12s config. That’s not so great. While it will give you high enough speeds to keep up with cars on a freeway, your VESC will fry before that. VESC’s have an ERPM limit of 60K, and that would go way over.
Then there is my solution
You get two 4s batteries, creating an 8s series config. 8s is the perfect solution because it won’t exceed the VESC’s ERPM limit and you still get a realistic top speed of about 25 I think, I don’t remember…
This only makes sense if you go with your original motor choice. Which I think will save in the long run, you don’t have to buy wheels, trucks, motor mounts, any of it. An 8s battery with that is the optimal solution.
hope i helped
Wtf , 25 a continious? Well i dont know How thats work for you, but thats way to little for me. I didnt say it woldnt work for him, but I said the voltage sag will be veery much If plan to do lots of hill clims. Its also not good for the batteries, to be used at their limits all the time
when i use 2 4s battery i hit a top speed pf 19 mph weighted, i think i should go with 2 5s battery with a top speed of 25 mph but i got know idea it can handle those amps
or i could use
and how do you calculate the amps
We must keep in mind that @GrecoMan is very light
His point is still completely valid. I barely pull 60A cont from my battery on maximum acceleration, but that is with two motors. I’m also fairly certain that I am probably heavier than him as well.
You could use this website to calculate the battery amps using the mAh rating and C rating.
https://www.kritikalmass.net/battery-calculator/
But the manual calculation is multiplying the mAh rating by the C rating and then dividing by 1000.
For example, a 12S1P 5000mAh pack with a discharge rating of 30C would be 5000*30/1000 = 150A max
Keep in mind this is optimal conditions but those are the calculations behind it
If you want to save a little bit of money you could go for 6364 (has plenty of power) but then again it’s only like $10 or something.
I am like 99 lbs
This is what i am thinking to do 2 5s battery’s
Dual motor http://www.diyeboard.com/dual-belt-drive-1400w2-n5055-motor-power-truckfront-truck-kit-p-422.html and 2 vescs products/torque-esc-vesc-bldc-electronic-speed-controller
using it as 10s I assume?
yes connect in series
but wich connecter do you need to connect the 2 vescs
you need different motors. 270kv on 10s will destroy the vesc

or
with the one from diyeboard.com i can make a dual motor setup with http://www.diyeboard.com/dual-motor-beltdrive-mechanical-kit-for-5055-6354-motors-p-543.html
no, don’t use the one from diyeboard. much lower quality than the APS one
the APS one in a single drive will probably give you more power anyways
Should i do a single or dual motor setup
singles is cheaper, you could always upgrade later on
