Hi,
I want to supply an esp32 module (5V) from my 36V ebike battery.
An obvious solution is using a cheap aliexpress switching stepdown converter.
However, most of them seem to use an LM2596 regulator and define 40V as upper input voltage limit.
As we all know, a fully charged lithium battery can go up to 42V.
So, is it safe to use such a step down, or should I place a couple of diodes in front to lower the voltage just a little?
Maybe there are better solutions that would even work with a 48V battery? Any suggestions?
