100 mW
Background: I don’t know much about electricity. I have a 14s5p battery that Id connect to my inverter (rated to handle 40-60w DC). The few times ive used the inverted it has never been an issue (always keeping battery under 58v). My battery would connect using Anderson connectors, id turn on battery, then id turn on inverter. Worked perfectly fine.
Today I wanted to test something so I took some old Chinese cells from a 'dead' 48v pack (was 13s) and made a '12s battery pack'. Each cell measured at 4.01v (give or take 0.01v) and the pack measures a tad over 48v. I attached the positive wire of the inverter to the battery, then the moment I touched the negative wire (black wire) to the other end of the battery there was sparks, bright light, and some metal of the ring connector was melted/charred. I don’t know what I’m doing, any idea what happened?
On a side note: Currently the inverter is also dead (does not even work on my normal battery). I cracked open the top and there are six fuses (3x20 and 3x10). Hoping if I replace the fuses it will fix the inverter, but ill have to order some fuses.
