標題: Inside secret of Hobbywing 120A v2.0


Hobbywing 120A v2.0 uses 24 pieces On semiconductor NTMFS4833N Power MOSFET (~HK$7 each in bulk buying) which can stand 30V maximum but the capacitor provided is only 16V max. NTMFS4833N is commonly used in top quality of ESC such as LRP TC Spec, Mamba, etc. HTC LM39302 is used for linear BEC output.

Changing higher voltage of capacitor and use external BEC, maybe we could use 4S-6S Li-po, I use 4S A123 with no problem using the existing 16V capacitor.

nice.
can i modify 60A version to 120A?

用唔同既capacitor對爆炸力有無影響?

As I know, 60A uses another MOSFET, not the same as 120A

I guess that's why he wanted to modify it

睇番datasheet,定義一樣既
對位吹出泥換都唔係唔得

買個 "好很型" 80A 4s lipo 都係 4 舊水 .... 點解搵個 8 舊電變黎搏 ？ ？ ？
