What are the differences between Mini FSESC4.20 and Mini FSESC6.7?
| Mini FSESC4.20 | Mini FSESC6.7 | |
|
Voltage |
8～60V（3～12S safety） | 14V-60V（4～12S safety） |
| Max Continuous Current | 50A | 70A |
| Instantaneous Current | 150A | 200A |
| ERPM | 60000ERPM | 150000ERPM |
| Driver | DRV8302 | DRV8303 |
| Current Sampling Resistor | Two 1mR domestic manganese copper resistors | Three 0.5mR imported manganese copper resistors |
| Mosfet | Six TPH3R506PL | Six NTMFS5C612NL |
| Size | 67*39*18.3（mm） | 67*39*18.7（mm） |
| Heat Sink Thickness | 9mm | 10mm |
1.Voltage range
Mini FSESC4.20:8V-60V (3S to 13S LiPo)
Mini FSESC6.7:14V-60V (4S to 12S LiPo)
However, we suggest to use our FSESC under 55V, because the VESC tool is auto-disconnect when you set up to 57V (if you're choosing vesc_default.bin)
2.Current:
Mini FSESC4.20: max current 50A, peak current 150A
Mini FSESC6.7: max current 70A, peak current 200A
This is the main big spec difference between them. so if you're not using so much higher current, V4 is a good option due to it's far more cheaper than V6.
3.Power:
Power = voltage * current
Mini FSESC4.20 power: 50A*60V=3000W
Mini FSESC6.7 power: 70A*60V=4200W
4.Speed limit:
Rotation speed (ERPM) = motor speed (RPM) * motor pole pairs
The limit speed of Mini FSESC4.20 : 60000 ERPM
The limit speed of Mini FSESC6.7 : 150000 ERPM
5.Current Sampling Resistor:
6.Mosfet:
