Notes
pins counts the two power contacts; an IC3 plug also carries a small Smart data contact beside them, which Spektrum's adapters wire through ("an internal Smart connection wire on IC connectors", https://www.horizonhobby.com/product/spektrum-one-piece-battery-adapter-ic3-device-ic2-battery-2/SPMXCA520.html). Spektrum states that IC3 and IC5 connectors are backwards compatible with EC3 and EC5 connectors (https://www.horizonhobby.com/product/spektrum-s2200-g2-ac-2x200w-smart-battery-charger/SPMXC2010.html); an EC plug has no data contact, so the two mate for power only.

Mating face, data contact at the side
Not to scale: drawn as the EC3 it mates with for power (Amass's EC3 sheets), with the Smart data contact beside the sockets as Spektrum's photos of its Smart batteries show it; its size is not dimensioned in our sources. Spektrum: IC3 and IC5 connectors are backwards compatible with EC3 and EC5 connectors.
