I am looking for a DC barrel to power a battery pack. The battery in question is connected in 10S3P, that's is a nominal voltage of 36V. I am currently looking for a DC barrel that can withstand at least 42V and currents up to 2A.
I have seen some companies that charge the battery pack using a RCA plugs, however would like to avoid using them because they are not design for that. I have check DC plugs but I can hardly find that can withstand 42V or higher. However, most of them are design for 24 volts.
I was wondering if I could use them as long as I maintain the power output within the safety threshold. Let's say that the dc plug has is designed to safely withstand 24V and 5 A. Could I used with 42 volts and 3 amperes. If not, what would be your advice?
