So I’ve got a 12s5p with 205kv radium 85’s running 150 m 70 b amps in the composite, but I want more power. Would the 205kv motors handle the 16s5p pack from my tomiboi? Erpm is apparently fine for a spare d75 i have.
Was thinking either the battery swap and a new pack for the 4wd or 4 7s lipos to go into the composite for 14s2p.
Resistive power loss is probably the biggest loss and heat producer and limiter of the motor’s power as we use them on a board with little wheels and like a 3:1 but I think with some setups switching losses (hysteresis and Eddy currents) can add up with how fast the motor is spun and can be close to resistive losses if not more and that’s likely a good thing.
Ideally you’d want half resistive losses and half switching and that will keep your motor coolest with most power, so using a high kv and high voltage and biggest gear ratio possible is likely ideal for keeping the motor cool, and possibly giving the most torque.
@Evwan whats ur no-load loss at highest speed with that high kv and voltage? At what erpm?
That was still 16s with the top box. I’m not writing it off but if I end up using the 16s5p in the composite like your old setup I may try 16s2p lipos in the 4wd. Was talking to yogajitsu and he runs his 12s2p 4wd 120amps a corner with no sag apparently
