DEYE GB-L-Pro-Pack4.1 Battery module, 4.09 kWh, HV, used

We offer a completely new battery module (with approx. 3 cycles), which was used during the testing of the entire stack. This module was diagnosed, charged to SOC 100%, and is suitable for expanding the existing battery storage. We supply it complete in the original box and with the original 10-year warranty.

The high-voltage stack architecture provides wireless connection of modules, which increases efficiency and significantly simplifies the installation and expansion of the system up to 16 parallel stacks. Thanks to the modular configuration of 2–6 units in series, capacity can be flexibly scaled from 4.09 kWh and output voltage optimized at 102.4 V for demanding energy applications. Modern LiFePO4 technology ensures long lifespan, stable performance, and high operational safety even with intensive daily use in an outdoor environment.

Safety, Control, and Long Lifespan

Comprehensive protection includes integrated explosion relief and quick fire response within 3 seconds, minimizing risks in critical situations. Intelligent thermal management with precise sensing of key components maintains stable operation in the range -20 to 60 °C. A clear LCD display, remote updates, and instant alerts provide smart and visible system management. The robust floor-standing design with IP65 rating and corrosion protection guarantees long-term durability even in demanding outdoor conditions.
