The EcoFlow 4kWh Independence Power Kit couples the Independence control set — Power Hub, AC/DC Smart Distribution Panel and Console — with two 2.048 Wh LFP batteries for a total of 4.096 Wh at 51,2 V nominal. It is the middle rung of the small-battery ladder, best suited to compact conversions where every kilo matters but a single 2 kWh pack would still be too tight. Each of the two 17,1 kg batteries measures 34,8 × 19,8 × 28,5 cm, so both can be tucked under a seat or against a bulkhead without the space penalty of a 40 kg block.

• 4.096 Wh usable storage split across two matched 2.048 Wh packs — enough for two to three days of light off-grid use in a small van.
• Combined 64 A charge and 160 A discharge headroom (32 A / 80 A per pack) keeps the packs comfortable even with a X-Boost 5.000 W burst.
• Three MPPT solar inputs (15-150 V, 30 A each) accept mixed panel orientations across the roof and, optionally, awning-mounted arrays.
• AC/DC Distribution Panel with 6 AC outlets and 12 DC circuits (6 adjustable + 6 fixed, 20 A each) removes the need for a separate DC busbar.
• Console touchscreen at 1024 × 600 pixels shows both packs and each circuit individually, useful for tracking down parasitic loads.
• Room to add a third 2 kWh pack later, up to 6.144 Wh, without changing the hub or the cabinetry.
