Compact Expansion Power for EcoFlow DELTA 2 / DELTA 3: The WattCycle 48V 50Ah GC2 LiFePO4 Battery with Bluetooth & Free Monitor stores 2560Wh of energy in a compact 51.2V 50Ah design, making it a practical external battery solution for compatible EcoFlow DELTA 2 and DELTA 3 Series power stations. When connected through a compatible WattCycle 48V Expansion cable, it can provide additional stored energy for longer off-grid stays, campervan travel and mobile power use. 2560Wh in a Compact GC2 Footprint: Despite its compact dimensions of approximately 264 × 183 × 331mm, the battery stores 2.56kWh of energy. Its narrow GC2-format enclosure makes it easier to position inside campervan storage compartments, garages or mobile power setups where floor space is limited. Portable at Only 20.1kg with Built-In Handle: At approximately 20.1kg, the battery remains manageable for a 2.56kWh LiFePO4 energy source. The integrated top handle makes it easier to move between a campervan, campsite, garage or portable power setup, giving users more flexibility than a permanently installed large-format battery bank. 100A BMS for Up to 5120W Continuous Output: The built-in 100A BMS supports up to 100A continuous discharge, equal to a calculated maximum continuous DC output of approximately 5120W at 51.2V. It also provides protection against over-charge, over-discharge, over-current and abnormal temperature conditions, helping protect the battery during charging, storage and high-load use. Bluetooth Monitoring Plus a Free LCD Monitor: Monitor the battery in two convenient ways. Built-in Bluetooth connects to the WattCycle App for real-time battery information on your phone, while the included LCD monitor provides an independent display for checking battery status without opening the App.This dual-monitoring approach is especially useful in campervans, where the battery may be installed inside a storage compartment. Expandable up to 10.24kWh: One battery provides 2560Wh, while up to four compatible batteries can be connected in parallel to create a calculated 10.24kWh battery bank. This allows users to begin with a compact single-battery setup and add more stored energy later as campervan or off-grid power requirements increase. Low-Temperature Protection for European Travel: The intelligent BMS includes low-temperature protection, cutting off charging when the cells become too cold and protecting the battery during winter use. The specified charging temperature range is 0°C to 55°C, while discharging is supported from -20°C to 60°C, making it suitable for a wide range of seasonal travel conditions. 6000+ Cycles for Repeated Deep-Cycle Use: The LiFePO4 cells are rated for 6000+ cycles at 80% depth of discharge, making the battery suitable for repeated charging and discharging in campervan and off-grid power systems. Compared with traditional lead-acid storage, LiFePO4 also provides a lower-weight, maintenance-friendly solution for users who regularly travel with portable energy equipment. Metal Housing for Mobile Power Environments: The rigid metal enclosure provides additional mechanical protection for the internal cells and electronics during transport and installation. Combined with the integrated handle and compact footprint, it creates a battery designed around mobile applications where the unit may be moved, stored or installed in confined spaces.
