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 rough everyday use. It can be used in all aircraft or ship models as well as in the R/C car sector.

Connections: XT60 connector with gold contacts, continuous load XH balancer connection. 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 if needed with an external NFC sensor, such as the Hacker or Jeti MTAG, and transferred into the transmitter telemetry. The built-in MTAG chip also offers the ability to manually or automatically count and store 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 they want to utilize the MTAG function or not. The TopFuel battery can be used without MTAG like any ordinary 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 through 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 capacity.
