EC3/EC5 vs IC3/IC5
Many RC enthusiasts do not know the difference between EC3/EC5 and IC3/IC5. Both look similar in appearance but function differently. Arrma’s IC3/IC5 is a new generation of smart plugs, commonly used in SPEKTRUM batteries, it needs to be used with the battery brand’s ID system charger. It is equivalent to combining an ordinary battery EC3/EC5 plug and a balanced plug into one plug. You can see a metal data pin in the middle of the male plug.
Compared with other batteries, SPEKTRUM batteries with IC plugs have functions such as automatic charging and discharging. It is very convenient and safe. When charging, you do not need to set preferences, the battery will automatically charge when connected to the charger, which is very suitable for RC beginners.
However, since these functions must be matched with their chargers, considering the price, some racers who are familiar with RC hobbies will often choose cost-effective alternatives. Just like Traxxas batteries, Arrma recommends you to buy their batteries with an IC plug along with the charger, you will spend more budget here. So if you become familiar with these products, I recommend looking for some better lipo battery replacements.
