About This Part
Battery pack impact bar assembly for the BYD Seagull, referenced by OE 13644586-00 and EQEA-5103930. This steel cross bar mounts under the floor along the traction battery, taking side-impact and stone loads before they reach the pack. It fits Seagull Smart Driving (2025-2026), Seagull Glory (2023-2025), the 2023-2025 Seagull and the 2025 Seagull (2023-2025). The battery guard bar bolts to the factory brackets at each end, so the underbody impact beam seats on the original mounting points. Fit it back with the correct torque to keep the pack protection intact.

Frequently Asked Questions: OE 13644586-00
The number on my old bar does not match, what do I do?
If the number stamped on your old bar does not match 13644586-00, do not fit this one on the assumption it is close enough. Check the model and the model year as written on your registration document, then compare that against the fitment table on this page. Matching the year first is the safest way to confirm the correct impact bar, rather than relying on the number alone if it does not agree with what is printed here.
When can I expect this impact bar to arrive?
Delivery time is confirmed with your quote. When the parcel arrives, check the outer packaging for any damage before you sign for it. While you wait, take the old bar out and note its fixing points, then compare them with the photographs on this page so you can confirm the shape before you start fitting. The shipping cost is confirmed with your quote.
How will a part this size actually turn up at my door?
Delivery time is confirmed with your quote. The packaging details are shown on this page. While you wait, check the side of the car the bar sits on underneath, and look at the position and the fixings holding the old one in place. That way you can see straight off whether the fixing points line up before you start the fit, rather than working it out with the new part already in your hand.
What is this bar actually made from?
Made of metal, this bar is a structural piece rather than a plastic trim, so it is fitted to protect the battery pack underneath rather than for appearance. If you are cross checking part listings elsewhere, this is also listed as EQEA-5103930, which can help confirm you have found the right item when searching under a different reference. Have that alternative reference to hand if you are ordering through another source or checking stock against it.
Will I need to get this painted to match the car?
Supplied in black, this bar is not something you need to send off for finishing before it goes on. As it sits underneath the car rather than in view, matching paintwork is not part of what you need to sort. What does matter is confirming fit, so check the number stamped on the part you are taking off against OE 13644586-00 before you order, to make sure this is the correct replacement for your Seagull.
Where does the impact bar sit under the car?
It fits underneath the battery pack on the underbody, positioned to guard the pack from below. The photographs on this page show its mounting position and orientation from several angles, which is the clearest way to confirm you are looking at the right area of the car before you order. This is a new metal assembly, listed for the BYD Seagull under OE number 13644586-00, also listed as EQEA-5103930. Have that number to hand when you check the images against the underside of your own car.
