 If you are comfortable with using a soldering iron and doing some delicate soldering, you can
-"easily" (sort of) swap the connectors and the 12V and GND wires. The 3 wires for the 12V supply
-and the 3 GND wires are shorted, so they're not going to different cells and it's not important
-whether you swap 1-2-3 with 7-8-9 or 9-8-7 or 7-9-8 or 8-7-9 or … (and vice versa).
