The Hacker TF ECO-X is a high-performance lithium-polymer battery designed for RC flight models. With 4500 mAh capacity and a 22.2 V nominal voltage across six cells, it delivers the sustained power output required for demanding aerial applications.
4500 mAh capacity provides extended flight times per charge cycle
20C continuous discharge rate supports high-draw motors and aggressive maneuvering
XT90/AS connector ensures a secure, low-resistance power link to the ESC
MTAG balancing connector enables precise cell-level monitoring during charging
What sets the TF ECO-X apart
The ECO-X series uses Hacker's proprietary cell formulation and construction to balance energy density with thermal stability. The compact 140 × 43 × 48 mm profile and 595 g weight are optimised for the size and payload constraints of modern RC aircraft without sacrificing capacity.
Ideal for...
RC pilots and builders who need a reliable, high-discharge LiPo pack for 6S configurations — from sport flying and freestyle to mild 3D manoeuvres. The 20C rating suits moderately aggressive flying styles; for full-throttle 3D, a higher C-rate pack is recommended.
Application of the Hacker TF ECO-X
Verify that your ESC and flight controller support 6S LiPo input (22.2 V nominal)
Connect the XT90/AS plug to the power leads; ensure polarity matches
Use a charger with LiPo balance support and connect the JST-XH balancer port
Store and charge in a fire-safe bag; never leave unattended during charging
Hacker is a German manufacturer specialising in RC power systems, including LiPo batteries, chargers, and speed controllers for the model-flying market.
It powers RC flight models that require a 6-cell LiPo pack, such as sport planes, trainers, and freestyle aircraft drawing moderate to high current.
The main power leads use an XT90/AS connector, and the balance port uses a JST-XH connector for cell-by-cell voltage monitoring during charging.
Lithium-Polymer chemistry, 22.2 V nominal (6S), 4500 mAh capacity, 20C continuous discharge rate, 140 × 43 × 48 mm dimensions, 595 g weight.
