The ECO-X cells have proven themselves thousands of times and strike the perfect balance between durability, weight, and lifespan. The battery comes pre-soldered with the XT60 connector system and is ideal for rugged everyday use. It can be used in all aircraft or marine models as well as in the R/C car sector.

Connections: XT60 connector with gold contacts, continuous load XH balancer connector. An internal chip for battery telemetry stores battery data such as type, number of cells, capacity, C-rate, or battery ID on the passive MTAG chip. These values can be read out with an external NFC sensor if needed and incorporated into the transmitter telemetry. The built-in MTAG chip also allows for manual or automatic counting and storing of charge cycles. When using multiple identical batteries in series or parallel operation, more effective active battery management becomes possible.

Note: It is up to the user whether to utilize the MTAG function or not. The TopFuel battery can be used without MTAG like any standard battery.

Voltage Indicator Technology: The TopFuel battery is delivered with the proven Voltage Indicator technology. At the push of a button, the charge status of the battery is displayed via four differently colored LEDs. The Voltage Indicator helps to accurately assess the battery's charge status at any time.

Factory Optimized: The special manufacturing process, where the batteries are pressed during filling, makes these cells up to 10 percent thinner and more robust than comparable cells with the same capacity and load rating.
