Hi I’v been using a vesc x on 6s for a while and have noticed it runs significantly worst on 6s. Has anyone else seen this happen?
Because you have to pull a lot more amps causing it to heat up faster compared to higher voltages.
That’s just the simple answer.
6s 3.76=22.2 Volts x 45amps = 1000w 12s 3.76=44.4 Volts x 22.5amps =1000w
Provided equal top speed with either different kv motors or gearing the 12s “should” run less hot due to lower amps.
Especially with P=I²*R you have 4 times the loss when using double the amps.
What are your motor KV and low voltage cut-off parameters looking like? A 140KV motor is never going to work as well on 6S as it is on 12S.
I don’t think the performance difference you’re seeing is strictly due to higher amps being pulled.
After further inspection I’m actually noticing that I’m hitting the rmp limit on the vec this Chinese motor is mislabeled as 260kv its more like 360kv yeahh… Thanks For The Explanation.
