Description
Massively expand your DELTA Pro Ultra system’s storage at a flash sale price with this exclusive bundle — 2x EcoFlow DELTA Pro Ultra Smart Extra Batteries plus a free trolley for easy transport. Each battery adds 6,144Wh of LiFePO4 storage, and together they bring 12,288Wh of additional capacity to your DELTA Pro Ultra system — enough to power a home’s essential loads for an entire day or more during a grid outage, all at an exceptional flash sale price point.
Each DELTA Pro Ultra Smart Extra Battery connects to the DELTA Pro Ultra Inverter via a dedicated expansion port and is auto-detected immediately. Multiple batteries combine to scale the system’s total storage — with two batteries added to the base system, total capacity reaches 18,432Wh, and with additional units the system scales all the way to 30,720Wh per inverter. LFP chemistry provides over 3,500 charge cycles, and the inverter manages all charging and discharging automatically, prioritizing solar input when available for maximum renewable self-consumption.
The included free trolley makes moving these substantial battery packs simple — roll them between rooms, position them during installation, or store them conveniently without lifting the full weight. At over 100 lbs per battery, having a dedicated wheeled trolley is a practical essential for any DELTA Pro Ultra multi-battery setup. Flash sale pricing makes this the most cost-effective time to expand your EcoFlow home energy system’s capacity.
Compatible with EcoFlow DELTA Pro Ultra systems only. Backed by EcoFlow’s standard product warranty.
