box

Today I burned one mosfet with 200W charger and 4S lipo. There is no
discharge amperage limit. It should be auto limited to 20W depends on
voltage.

Thanks but I bought it arleady. It was IRF3205

Hi shaggee,
there is a 5A current limit and 25W power limit when discharging,
But the limit is not active during calibration,

Can you give more details when this happened?

from cheali-charger.

I done voltage calibration first. Added 5000mah 4S lipo for battery memory. I started discharge+balance. Charger started, i saw arround 1800mA discharge (on fully loaded 4S lipo). 16.8V*1,8A=30W. After 30 seconds i smell smoke and I saw light inside charger. Mosfet and 5W ceramic resistor got burned.
I think it was my bad. I forget to do discharge calibration but without calibration charger should show max 1,2A not 1,8A.

Hm... you shouldn't be able to set the discharge current to more then 1.48A in the "edit battery" menu.
You can check what you've set?

I will check again tommorow.
A jak znów sfajczę to kombinujesz mi IRF3205 :)
BTW ten soft dla 200W pasuje do Hobbyking eco 6-10. Warto dodać do listy obsługiwanych.

hm... to zanim będziesz sfajczył to poczekaj :)
zadzwonię do Ciebie na skypa coby sobie chociaż popatrzeć ;)
ale na razie sprawdź tylko w menu, a później się zastanowimy co tam nie gra.

problem solved: battery discharge without discharge current calibration.
