Batteries with different capacities in parallel
Hello all!
Trying to run two 48v lithium batteries with different capacities in parallel, they'll have a current draw of 20 amps with a max of 30 amps.
I'm planning on using the STPS61L60CW which is a dual pair Schottky diode with a low forward voltage and can handle 30amps.
I'm also "designing" a PCB with lugs that can handle the amperage, and with traces wide enough to handle the amp draw (11mm traces, double layer).
Is there anything I'm missing or should be considering? I'm a bit concerned about the heat from the diode, at a max of 30 amps and a forward voltage drop of .7v -- how big of a heatsink do I need to dissipate 20 watts?
