How often do you charge your batteries?

Once per few moths. When BMS  reports that. The battery pack is 5S 240Ah LiFePO

Meanwhile i found that the tp-link media converter is easy to run without it's buck converter if one feeds a 3.3 V about 200 mA linear supply. And it has a metal case.
The NI GPIB-ENET/100 is worse in that respect. It contains two LM2595S switching converters, one for 5V and one for 3.3 V, both with open ferrite inductors. Its enclosure has a metal base with a plastic cover.
Therefore i am studying a STM32H7 based ethernet solution - also avoiding the NI proprietary protocol and their drivers.

Regards, Dieter
