Re: Fets for ESC
Yes it worked .... also I replaced 20 AMP esc with 30 amp capable FETs.
This you can do only once you verify the specs through datasheets.

Re: Fets for ESC
wow that is so much to help,thanks alot,you should probably show this to everyone,and i was supposed watch it yesterday,but i didnt,because i thought was just another boring video.That guy is lifesaver,i have like 8 burnt escs,and now i know what to do with them.And the final question is,i dont have a multimeter,but now iam going to get one,probably a cheap one,and i need to know one thing,can i get the same beep sound for a cheap Rs300 digital multimeter?,i know it is a dumbest question anyone could ever ask,but really need to know.

Re: Fets for ESC
Continuity checker is the basic'est feature of a multimeter.
Still check before buying

You can also make a simple continuity tester with a buzzer and battery

Re: Fets for ESC
for good spec P/N mosfets try inkocean or hacktronics. I'm right now repairing my burnt B6 charger (reverse connection of power
)
i found this video very simple and informative for checking Mosfets.

https://hacktronics.co.in/module/wtblocksearch/catesearch?fc=module&module=wtblocksearch&controller=catesearch&orderby=position&orderway=desc&search_category=all&search_query=P+mosfet&submit_search=
some parameters to look for.
P-Mosfet Vds -v ?, Id -A ? Rds on ohms ? and Vgs 2.5 or 4.5 or 10v etc should check the graph.
N-Mosfet Vds +v?, Id +A? Rds on ohms? and Vgs 2.5v or 4.5v or 10v etc.
and physical shape of the fet (package) like SOIC 8pin or SOP 8 etc.
