Most 52v batteries I have seen are built for use with the Bafang BBS motors, which only draw 30 amps max. A battery being overdrawn will lower it's voltage output as it struggles to output enough amperage, low enough and the controller will interpret it as being dead and turn off to avoid damage to the battery. Legal restrictions for the use of combustion engine driven model aircraft in some countries, [ citation needed] most often due to potential for noise pollution—even with purpose-designed mufflers for almost all model engines being available over the most recent decades—have also supported the shift to high-power electric systems. Anyhow, now that we don't throw as many parties anymore since we've become serious the extra fridge in the garage is good for something again.

tube convention (dual-mode rectangula) controller, function: positive power supply, negative power supply, electric door lock, motor phase line, for Hall line, accelerator throttle grip line, three-speed shift line, low-level brake line, high Level brake line, ordinary instrument line, anti-theft alarm power line, anti-theft alarm signal line, reversing line, intelligent identification self-learning line.

Do NOT try to hack this device to work from a lithium battery yourself, again you'll either risk a fire or you'll simply go through batteries all the time. The friction of the brushes sliding along the rotating commutator segments causes power losses that can be significant in a low power motor.

Aeromodelling [ edit ] A microprocessor-controlled BLDC motor powering a micro radio-controlled airplane. I thought I would get more speed than I'm getting now, could a upgraded controller help with more speed ? On the other hand if the cells AH capacity is rated at less than 1000mAh, then it won't last long or may even not start a 3A motor. In modern washing machines, brushless DC motors have allowed replacement of rubber belts and gearboxes by a direct-drive design.

Brushed DC motors develop a maximum torque when stationary, linearly decreasing as velocity increases. On a different controller, you've got to try and identify the the voltage divider that deals with it, and change the resistor in the same way.
