The Xtron is our best-selling battery series, which we have had in our range for almost 15 years. Of course always up to date with the latest technology.

The battery combines maximum performance with balanced properties.

It is deliberately massive and heavier. The slightly higher weight has a positive influence on heat development and thus on stability. The Xtron stays cool even under high loads and difficult conditions, which increases durability (cycle stability).

We can safely say that the Xtron series is one of the best performing yet most durable RC lithium batteries on the market. It is therefore the first choice for both beginners and professionals.

If the use of a lightweight cell is required, we have a perfect alternative in the Quantum.
