    Reliable 72V to 12V converter for my EV
    I’ve been using this 72V to 12V buck converter in my electric vehicle and it’s been working well so far. The aluminium case seems to handle heat nicely, and the IP67 rating is useful for an EV setup. The 12V output stays stable with very little ripple. Wiring was straightforward, and the built-in protections are a nice bonus.
