Pentium-80A-OPTO are  products in "PENTIUM" series. "PENTIUM" series has the full range of ESCs from 6A to 100A.

 Specifications:

• Output: Continues 80A, Burst 100A up to 10 Secs.
• Input Voltage: 5.6V~26.0V ( Lithium : 2~6s or NiMH/NiCd  5~18 Cells)
• BEC (Battery Elimination Circuit) Output: Pentium-80A-OPTO: None. Pentium-80A-OPTO is often used with an UBEC
• Max Speed: 210,000rpm for 2 Poles BLM, 70,000rpm for 6 poles BLM, 35,000rpm for 12 poles BLM. (BLM: BrushLess Motor)
• Size: Pentium-80A-OPTO:70-mm*31mm*14mm(width*length*height)Weight: Pentium-80A-OPTO:58g
• Packaging include: 3 sets of gold plated motor connectors and heat-shrink tubings (Remark: motor connectors and heat-shrink tubings need to be purchased additionally)

Features:

• Safety Arming Feature: Regardless the Throttle Stick position, the motor will not spin after battery connected. This will prevent any injury happened.
• Throttle Calibration: Throttle range can be configured to provide best throttling linearity, fully compatible with all market available transmitters.

Programmable Items:

• Brake Settings: brake enabled / brake disabled, default is brake disabled
• Battery Type: Li-xx(Li-ion or Li-poly) / Ni-xx(NiMh or Nicd)¡Adefault is Li-xx.
• Low Voltage Protection Mode(Cutoff Mode): power reducing / power cutoff, default is power reducing.
• Low Voltage Protection Threshold(Cutoff Threshold): low / medium / high, default is medium cutoff voltage.
• 1)    For Li-xx battery: Anumber of battery cells are judged automatically¡Alow / medium / high cutoff voltage for each cell are: 2.6V/2.85V/3.1V. For example: 3 Cells Li-Poly, when medium cutoff voltage is set, the cutoff voltage is: 2.85*3=8.55V.
• 2)    For Ni-xx battery, low / medium / high cutoff voltages are 0%(ie. never cut off )/45%/60% of the startup voltage. For example: a 10 cells NiMH battery pack, fully charged voltage is 1.44*10=14.4V, when medium cutoff voltage is set, the cutoff voltage is : 14.4*45%=6.5V.
• Startup mode: normal / soft / super-soft, default is normal startup.
• Timing: low / medium / high, default is medium timing. In normal cases, low timing can be used for most motors. But for high efficiency, we recommend the Low timing for 2 poles motor and Medium timing for 6 poles and above. For higher speed, High timing could be used.
• Full Protection Features: Low-voltage cutoff protection / over-heat protection / throttle signal lost protection.

 Advantages:

• Military Standard Capacitor with extremely low resistance used on voltage input section, this will increase the ability of prevention of unwanted RF Noise/ Interference during flying.
• Seperate PCB for control circuit and MOSFET circuit: adiabatic air gap between control circuit PCB and MOSFET circuit PCB reduces the heat exchange form MOSFET to control circuit, so the ESC works more reliable.
• Extreme low resistance, super current endurance.
• Microprocessor and BEC use separate voltage regulator IC, with good anti-jamming capability.
• Compatible with Hobbywing's Program Card .
