Questions
Buying a used EcoBoost Hybrid 48 V pack
Still unsure which pack is right? A specialist can check fitment with you.
Talk to a specialistA belt-driven integrated starter/generator takes the place of the alternator. It recovers energy when the car brakes or coasts, stores it in the 48 V battery, then works as a motor to assist the engine when accelerating. The car cannot drive on the battery alone.
Ford EcoBoost Hybrid 48 V battery packs with a fixed price on ReBattery are listed from £42 to £168 right now. The price depends on condition and measured health, and some sellers take offers instead. Fitting by an EV garage costs extra.
Under the front passenger seat. Ford put it there so the Focus keeps its boot and cabin space.
Not confirmed. Ford built a 48 V air-cooled lithium-ion battery into all three, but no two sources confirm it is the same part. Check the label and part number against your car.
Check the car is a 1.0 EcoBoost Hybrid, then read the label on the battery. Send us a photo of the label and we will check.
You have 7–14 business days to inspect it. Raise it with evidence and the seller is not paid until it is resolved.
