What battery do I need for my ESC?
Your ESC is rated for operation at 6-12V, which suggests that you could use a 7.4V or 11.1V Lipo battery. Battery capacity and ‘C’ rate should match the expected current draw and run time. For example if the average current draw is 15A and you want to get 10 minutes then you need at least 15*(10/60) = 2.5Ah or 2500mAh.
Is higher amp esc better?
A high amp esc will usually have better internals than a lower amp esc. Keep tthe questions coming, you do not learn without asking! Amp rating generally means you can run a more aggressive motor (mod motors) with higher amperage. For example, the Hobbywing Justock is just a 45a ESC.
What is the relationship between ESC, batteries and motor?
Working voltage of the motor is decided by the ESC, whilst the voltage of ESC is decided by the output of batteries. Hence the total voltage of batteries must be equal or less than the maximum voltage of motor. Maximum voltage of ESC should not be higher than what the motor can suffer. Current in ESC is larger than motor.
What kind of battery do I need for my ESC?
Your ESC is rated for operation at 6-12V, which suggests that you could use a 7.4V or 11.1V Lipo battery. Battery capacity and ‘C’ rate should match the expected current draw and run time. For example if the average current draw is 15A and you want to get 10 minutes then you need at least 15*(10/60) = 2.5Ah or 2500mAh.
How do you know the battery capacity of a lipo ESC motor?
If the voltage is listed, divide by 3.7 (Voltage of one Lithium cell) to get the number of cells. Battery capacity is a measure of how much power the battery can hold and is rated in milliamp hours (mAh). You can figure out the Battery capacity you need once you know how much current your motor needs and how long you want to run it.
What’s the commutation speed of a Brushless ESC?
All brushless ESCs have a maximum commutation speed, beyond which the motor may stutter or lose sync. With a Kv of 2200rpm/V your motor will spin at ~11.1*2200 = 24400prm on 11.1V when running free. It has 14 poles, so it is electrically equivalent to a 2 pole motor spinning 7 times faster, ie. ~170000rpm.
