    Two 35v 470uF electrolytic input caps
    5v reg TA7805F, max Vin 35v
    Atmel ATMEGA 8L
    LT1262, a 5v-to-12v charge pump, presumably to make 12v for gate drive
    Three IR2101S gate drivers. Uses floating high sides, the high side can go up to 600v.
    12x output transistors, 2x per half-bridge:
    In mine, 11x are FDD6688 (30v Vds, 84A, 5mOhmn @
    10V Vgs) and oddly enough ONE FDD8896 (30v Vds, 94A, 5.7milliohm Rds-on @ 10v)
    Cheap controllers often don't use gate driver chips. So this is pretty decent.
    The 5V reg is not well heatsinked. If operated with a high input voltage, if you draw a lot of current out of the BEC you can easily overheat the 5v reg. True in most of these.
    Absolute max voltage is 30V here, limiting factor is the transistor Vds-max.
    It sounds like it CAN go up to 6lipo (4.2v*6=25.2v). Just barely, but it can. Should be able to work on a 24V sealed-lead-acid battery too, but that could be 28.8V while charging, very risky. If the ESC isn't turned on until it's taken off the charger and left to rest a minute, it'll be FINE.
    Oddly enough, when both sides of the H-bridge are off, the transistor voltage breakdown rating is up to 60v, in which case the 35v rating of the caps and voltage reg are the limiting factors.
    I've never actually turned it on. This is an Aspie Tech Review.

    The price is very good
    Came without program manual, and it was very difficult to find. So after some days on google, find this manual and would like to post hear: http://www.suppomodel.com/ESC/4_Main_Options_ESC__50A_and_above.pdf
    If you need the best price, buy this. If you need more options on program try other version like blue series of Mystery. I will resume program options, in the case of the link provided expire:
    Option 1: Battery Type (music+1 beep)
    1 Short+1Long Beep > NiMH/NiCD
    1 Short+2Long Beep > 3S Lipo
    1 Short+3Long Beep > 4S Lipo
    1 Short+4Long Beep > 5S Lipo
    1 Short+5Long Beep > 6S Lipo
    Option 2: Brake (music+2 Beeps)
    2 Short+ 1Long > No Brake
    2 Short+ 2Long > Soft Brake
    2 Short+ 3Long > Medium Brake
    Option 3: Throttle (music+3Beeps)
    3 Short+ 1Long > Soft Acceleration
    3 Short+ 2Long > Medium
    3 Short+ 3Long > Hard
    Option 4 : Throttle Range (music+4beeps)
    4+1 > Auto Throttle range
    4+2 > Manual set Throttle range
    Manual throttle setting: when select this option. The ESC will memory the Max/Full throttle
    when you enter the programming mode and the Min/Lowest throttle point when you exit
