Our most powerful ESC now with a more compact design, wider voltage range and lower price! the Turnigy Fatboy V2 speed controller is rated at a massive 300 Amp continuous current draw and 380 Amp burst!
The Fatboy V2 features a large aluminum heat sink case, dual 8AWG input wires, 8AWG output wires for the motor and anti-spark protection.
This ESC is suited to large scale 100cc plus electric conversions.
Voltage: 18.5V-55.5V (4s-15s Lipo)
Current: 300A (380A surge within 10 seconds)
BEC: No BEC (Opto)
Size: 120mm x 72.5mm x 27mm
Auto detect Lipo cells
Fully Programmable LVC
Start up type
This ESC is suited to R/C model applications only. Do not attempt to use it to power Push Bikes, Mountain boards, go-karts or similar machines. The programming logic is only designed for R/C Plane and Heli use. No warranty will be offered for incorrect use of this item.

Can I purchase a program box?
Or is there another way?I bought two of this and disassembled it which found there is problem in contact between MOSFETs and heat sink(metal case). Most of the MOSFETs did not contact securely to the heat-conducting silicon pad. This reduced heat sink rate which is vital to its work setting. This maybe reason of burnt of many Fatboys.
I plan to modify the sink system (adding Heat-Conducting Silicone Grease) and add strong fans to it. A separate brushless motor(driving a 5030 prop.) and ESC maybe feasible and powerful enough. Use a twin potential meter together with CA120-70 ESC.Running it with 12 S and 120A at the moment. This is it. It stayes pretty cool and the trottle response is perfect. Want to increase to 15s with a bigger motor lateron.
