Hi All,
First time post in this group for me though I have been lurking for some time ?
Having recently discovered QRP Labs and being immediately impressed with the engineering within the QMX (congratulations Hans ??) I decided to take the plunge and whilst waiting to start my QMX build I have been musing over a suitable portable power supply.
For some time now I have constructed battery packs for my home brew projects because it gives me full control over the capacity and the scope of inbuilt protection, I decided in this case that it would also be nice to include some form of fast acting solid state over current trip i.e. an electronic fuse in addition to the traditional battery management / protection board. ?I was about to start recalculating component values for a design I had used previously but decided also to have a look at what might be available at low cost commercially and in doing so happened across this device?? Given the 1A/2A selectable trip levels and the relatively low price I’m going to order one and have a play with it. ?I thought in the meantime it might be of interest to others as the current range would seem to be compatible with QRP current drain.

SAFETY NOTE… ?I have a background in industrial electronics and control systems. Given the energy involved if you do not have appropriate skills it is safer to avoid working on high capacity batteries. ?My wife is a fire fighter in London and the recent up kick in battery related ‘incidents’, be it EVs or in domestic premises, is scary. ?I predict it to get worse as competition increases in the EV sector!
