During prolonged electrical grid blackouts, at remote industrial facilities, and in off-grid base camps where the built-in capacity of a primary power station falls short of sustaining heavy multi-day workloads, a dependable and scalable energy expansion solution is essential. Expansion battery 2560Wh VIDEX OASIS BG1-2500 VPS-BG1-2KW5 | gray – extra LiFePO4 power module for station capacity expansion is a heavy-duty energy storage reservoir engineered exclusively for integration with the VIDEX OASIS 3000W portable power station (VPS-SG1-3KW). This module delivers an additional 2560Wh of energy storage without the investment of purchasing a secondary inverter unit, allowing construction teams, emergency rescue crews, and off-grid facilities to construct a tailored, high-capacity electrical system.

The electrochemical core uses high-security Lithium Iron Phosphate (LiFePO4) battery cells delivering 2560Wh of rated energy capacity (50Ah at 51.2V platform operating voltage). LiFePO4 chemistry provides superior thermal stability and guarantees 4000 full charge and discharge cycles while maintaining at least 80% of original capacity, translating to over a decade of dependable daily service without cell degradation. The gray chassis is internally reinforced with structural aluminum load-bearing braces that isolate the cells from mechanical shocks, heavy transport vibrations, and physical impacts, with external dimensions tailored for vertical stacking alongside the primary power station. The unit incorporates a parallel scaling architecture: utilizing the supplied heavy-duty connection cables, a single OASIS 3000W power station can interconnect with up to 6 of these expansion battery blocks in parallel, expanding total storage capacity to a formidable 17.92 kWh.

The interconnection terminal handles substantial electrical throughput: input power during charging from the base station reaches DC 40–57.6V at 50A, while in discharge mode the pack supplies up to 70A continuous current (DC 40–57.6V) to drive the primary station's AC inverter. An integrated Battery Management System (BMS) continuously monitors cell voltage and temperature thresholds, shielding the battery against thermal runaway, low-temperature charging damage, overcharge, deep overdischarge, overcurrent, and short-circuit faults (with a 1720A short-circuit cutoff threshold responding in 9 milliseconds). System activation requires a short press of the power button, with an onboard LED status indicator confirming operational readiness, while precise charge levels, real-time power flows, and thermal data are synchronized and displayed on the host station's color LCD screen and within the Life mobile app. The pack operates across ambient temperatures from -20°C to +45°C during discharge and 0°C to +45°C during recharging.
