[* black] Each battery is wired to the next like this.
-[* black] Positive goes to negative
-[* black] Don't forget to put the heatshrink on before soldering the wires together.
+[* black] First, tin the ends of the wires by applying a small amount of solder.
+[* black] Don't forget to slide the heatshrink on before joining the wires together.
+[* black] Then hold the wires that you are joining next to each other while applying heat to melt the solder and permanently join the wires.
+[* black] Positive goes to negative, leaving a red wire at one end of the chain and black at the other. This is wiring the cells in series, which increases the voltage. So here we have 3 3.7 Volt cells wired in series, giving us a nominal 11.1 V battery pack.
