DC to DC / battery to battery step up charger

I think this is either unknown or new technology. It will let you charge higher voltage batteries from lower voltage batteries. Which can be really handy for charging on the go or adding power from mismatched batteries. The input voltage on the one I ordered is anything from 9 volts to 50 volts and the output voltage is 54.6 volts. Pretty cool!

I got one to be able to charge my E-bike battery from any battery from 9 to 50 volts. I have several battery options in hand I can now use to boost my E-bike's range.

DC-DC chargers have been around for a while to fit in vehicles so they can charge non-automotive type batteries (like Deep cycle or LiFePO4 batteries) from the alternator......but with the specific charge voltage parameters those other batteries need.

I didn't know and I have looked for such many times. So I suspect most people don't know.
