x1 10S LiPo or x2 5S LiPo in Series?

What do you think about this one

if you want to enjoy your esk8 to the maximum it is 100% worth of buying 2 maytech vesc’s 4.12 of their site on aliexpress.

You can compensate with buying these motors ( which I use and are very good and powerfull for their size) https://nl.aliexpress.com/item/New-Arrival-Racerstar-5065-BRH5065-200KV-6-12S-Brushless-Motor-RC-Motor-With-Gear-For-Balancing/32786621582.html?

There is also a 140 kv version, depends on your gearing, both are good !

Which motor is better 140kv or 200kv

Better isn’t the word. On one hand you will have more torque. The other is higher top speed. Which you can control by changing gear ratios. Probably limited to 10s with the 200kv motors or limit erpm within the vesc

140kv unless your voltage is under 8S

Thinking bout using 2 3s lipo dual motor with vesc
