I went from 12s Lipo with 230kv motors to 10s Li-ion with 190kv motors and gave up a lot of power on the low end and abt 8mph on the top end.
Shouldnāt you have done the motors the other way? 190kv at 12s etcā¦?
I go 30mph on my 10s 200kv dual build
I was gearing up for the vescās that I ordered. Thats why I went 190kv at 10s to keep the erpm at safe level.
Iām around 188lbs and Iām only getting a top speed of about 23mph with dual 190kv motors 10s li-ions and TB 12s Escās 15/36 gears 90mm wheels
What gearing? Iām not that much lighter at 175lbs. Iām sure i hit 190 with my backpack on, which I always have on. Iām running 16/36 83mm wheels.
EDIT: gotcha
are you using Vesc? Li-ions or Lipos?
Yep. I guess it might be because Iām using current control and youāre using duty cycle.
I canāt wait to try that current control!
Oh so you havenāt switched over to a vesc
havenāt got um yet
are you using Lipos?
I guess that explains why esk8 calculator isnāt very accurate for you too!
Iām using the space cell pro 4, so Samsung 25R cells. VESC settings are 35A per VESC battery discharge max (70A total).
when I was running 12s lipos 16/36 gears 90mm wheels 230kv motors and TB12s escās, I was only getting 28mph top
what motors are you running
chakaās OM5065 200kv motors.
A BMS or lipo charger will balance the cells every time it charges it fully. Do cells need to be balanced every time itās charged? No but it is safer, makes them last longer and increases performance of the cells.
That doesnāt mean you never need to balance them if you go this route youāll prob need to manually balance them with the power supply once in a while
Looks like dropping 2s and 1 pulley tooth and 40kv cost me 10mph Like when you go grocery shopping and get to the register. It really adds up. Thats ok, I donāt need to go 30mph anyway. Iām 58 and I need to start taking it a little easier. Although my balance and reflexes are pretty good for an old guy. Iāve handled a couple situations going over 30mph including speed wobble and managed to stay on.
That calculator doesnāt seem accurate. Iāve done the math manually and toddy and makevoids calculators make sense to me. According to those youre 230kv 12s setup should get 47mph at full efficiency, but at that speed efficiency goes down the toilet. Either way you should be going VERY fast, faster than me. But again, this could be due to using duty cycle over current control as well, not sure.
