Ultra flexible high grade silicone wire for battery leads, wiring harnesses and just about everything else. Priced by the foot (30 cm). All lengths will be supplied uncut (i.e. buy 4ft and get a single 4ft length of wire). For quad battery connections we generally use 14AWG for anything using 22xx and larger motors. For 1407 power systems, 18AWG is fine and fills an XT30 connector. The ratings below reflect constant current, which doesn't happen for long with miniquads.
