EC5 to TRX / XT60 / XT90 Adapter Compatibility

This pack uses an EC5 plug. If your ESC or RC vehicle uses Traxxas high-current connectors, XT60, or XT90, simply pair the battery with our solid-copper adapters:

➡ Individual EC5 → TRX adapter (recommended for Traxxas 8S systems): EC5 to TRX Adapter (3-Pack)

➡ Full adapter lineup for EC5 → XT60 / TRX / XT90 (3-Pack / 4-Pack options): EC5 Male to Parallel / XT60 / TRX / XT90 Adapter Collection

These adapters use solid-copper terminals (not electroplated brass), providing lower resistance and more stable current delivery for high-discharge applications — especially important for 4S and 8S brushless systems.

Notice:

• For the RC battery, only if the voltage and the plug match, then it will fit.
• Please stop charging immediately when the cell voltage has been charged to 4.2V (Normal cell voltage is between 3.7V~4.2V).
• To double make sure safe, please check first whether the battery surface is alright when you get it and whether the voltage is normal before using.
• If the new battery won’t hold a full charge or loss the charge very quickly in a short time, please use the Balance Charger to charge and recycle several times first.
