The EcoFlow 4kWh Prepared Power Kit combines the Prepared bundle — Power Hub and AC/DC Smart Distribution Panel — with two 2.048 Wh LFP batteries, for a total of 4.096 Wh at 48 V. It is aimed at compact camper builds and small off-grid installations where two lighter packs are easier to place and service than a single heavy one, and where a custom display or the EcoFlow app takes the role of the Console. Both packs use LiFePO₄ chemistry rated for 3.500 cycles to 80 % capacity.

• 4.096 Wh usable storage split across two matched 2.048 Wh packs — roughly two days of light off-grid use.
• X-Boost inverter delivers up to 5.000 W AC for kitchen appliances or workshop tools despite the moderate battery bank size.
• Three MPPT solar inputs (15-60 V, 30 A each, up to 1.600 W per string) cover mixed roof orientations on a compact vehicle.
• Alternator input 13-60 V, 60 A / 1.000 W max keeps the bank topped up while driving.
• AC/DC Distribution Panel with 6 × AC outlets and 12 DC circuits (6 adjustable + 6 fixed, 20 A) keeps installation wiring compact.
• Two lighter packs can be split across two mounting locations to balance axle loads in a vehicle build.
