Hi all. I have posted a few times before.... I have a 48v electric scooter. Moyer is 800w brushless i believe.... I replace the controller. With what ia in the pic.... I blew the mosfets up on the first so replaced.. Now what i would like to no thay are all magna chip MDP.1933 thing is all the nubers on each chip are different.. So do i just replace with all the same chips or replace with identical. Im verry good at soldering only 6 chips. Can anyone please help

buy a new controller, then try fixing it if you want to. Match the volts with the amps and brushless or brushed.

The seller on a Chinese website stoped selling them so. Cant get a replacement. The reason it blew was on a hill climb after a shunt... So wanted to re solder in some new mosfets. And have a backup... Just dont no wjat mosfets to buy as all labled mdp1933. But under that all different codes..

mdp1933 is the part number, just buy it https://www.magnachip.com/wp-content/uploads/2020/10/MDP1933-1.pdf
the other numbers are probably date code of manufacture.
