@bigben makes the best enclosures but I canāt recall if heās made the segmented ones yet or not. If he does, Iād go for his fiberglass ones. They strong.
Yes, but I was making a point. That point is that asking āShould I go with 10s6p or 12s5p?ā should not be answered with āGo with 12s5p, it has more range.ā Thatās demonstrably false.
does max motor override max battery. exampleā¦ if I have max battery set at 50 and max motor set at 60 will the system allow 60A to be pulled even though max battery is set at 50A?
Quick question. My cousin is trying to update his razorx piece by peice as he has a low budget. Could he put an aliexpress Esc like this #Aliexpress AU $72.88 33%OFF | 24V/36V Electric Skateboard Controller Remote Control Dual Motors Longboard ESC Parts Scooters Skate Board Accessories https://a.aliexpress.com/_s0aQit in and still use the 22v battery and motor? The Esc says it does 24v is this close enough or a really bad idea? If no are there 22v escs out there?
No, because they do different things. At low and medium speeds, the vesc acts a bit like a DC-DC converter: The switching of the mosfets, combined with the inductance of the motor, effectively step down the battery voltage to whatever is required at a given time. It is entirely possible (in fact, incredibly common!) to have more current flowing through the motor, than is flowing from your battery.
That does not mean thereās some free energy, overunity bullshit going on. The voltage is proportionally lower, you are getting the same number of watts. This is why you see people with, say, 40 battery amps and 80 motor amps. At low speed, under acceleration, the vesc will pull up to 40 amps from the battery, and deliver up to 80 amps to the motor, simultaneously.
TLDR; Battery amps =/= motor amps. They are not the same. They are not directly related.
the upside of setting the motor max higher than the battery max is you have more torque available at low to mid speed, without exceeding the battery max
the downside of setting motor max higher than the battery max is the motor max setting sets the motor current and torque at full throttle, but at the higher speeds it takes almost an equal # of battery amps to supply the full motor max, but if you set the battery max lower than the motor max, the result is at higher speeds, you lose some higher end throttle range, and this effect becomes more pronounced the higher you set the motor max above the battery max
see the circled area of the chart below with 100a motor / 60a bat vs 60a motor / 60a bat
But inside the enclosure to take up space I use any closed cell packing foam from boxes that come in the mail. Pack as much of that shit inside as you can. I usually cut it into strips averaging 1cm x 5cm -ish and stuff them everywhere I can
