FAQs & Tips
-
Battery runtime is estimated by dividing capacity (Ah) by current draw (A). This tool helps you visualize that behavior in real time under different loads and conditions.
-
Higher voltage increases power output and efficiency, but may also increase heat and stress on components depending on resistance and load.
-
Higher Ah means longer runtime, but it also increases weight, charging time, and cost. The optimal choice depends on your use case.
-
Most lithium batteries perform best between 15°C and 35°C. Higher temperatures can reduce lifespan and increase safety risks.
-
Higher internal resistance leads to energy loss, heat buildup, and reduced performance under load. Lower resistance = healthier battery.
-
They are highly useful for prediction and comparison, but real-world performance still depends on battery quality, age, and environment.
-
E-bike builders, engineers, DIY battery hobbyists, and anyone optimizing lithium battery systems for performance or safety.
Advanced FAQs & Pro Tips
-
BLDC motors typically use 3 phase wires and Hall sensors for commutation, while PMSM motors often rely on more precise electronic control and may include additional feedback systems for smoother torque and efficiency.
-
Power the Hall sensors with 5V, then measure signal output while slowly rotating the motor shaft. A multimeter or oscilloscope helps verify proper pulse switching.
-
Swapping any two phase wires reverses the magnetic rotation sequence, which changes motor direction without affecting performance or efficiency.
-
Most throttles use a 0–5V signal wire (usually white or green) and a ground wire (usually black). Always confirm with a multimeter before connecting to the controller.
-
A brake cutoff wire interrupts motor power when the brake lever is pressed, improving safety by preventing motor engagement during braking.
-
PAS sensors detect pedal rotation using magnets and send a signal to the controller to assist motor output based on pedaling speed and rhythm.
-
Extra wires may be for temperature sensors, encoders, or advanced communication features. Always consult the manufacturer diagram before connecting power.
-
Yes — it helps identify incorrect connections, missing signals, and mismatched wires, making fault detection much faster during repair or installation.
-
Always verify polarity, use proper fuses, connect low voltage first, and test step-by-step instead of powering the full system immediately.
