Complete 4-pin Hailong-style battery base mount plate with a pre-wired XT60 output lead. Hailong-1 (4-pin) and Hailong-2 (5-pin) bases use different cradle shapes and aren’t interchangeable — confirm your battery’s connector before ordering.
For any order above £19.90 shipping is free of charge.
You have the right to return your orders within 30 days.
12 months warranty from date of purchase.
4-pin discharge socket · Pre-wired XT60 output · 2-hole bottle-boss mount
This is the frame-mounted rail and socket that a Hailong-style downtube battery clicks onto, with a short pre-wired lead terminating in an XT60 connector for the rest of your build. It bolts to standard bottle-cage bosses, and the battery case’s own base slides down over the rail to make contact automatically.
This is the complete mounting rail, socket and output lead assembly — not the same product as our bare 4-pin connector spare, which has no rail or lead and is meant for repairing an existing base rather than replacing the whole mount. Choose this if the rail or mounting mechanism itself has failed; choose the spare connector if only the socket contacts have worn out.
Suits Hailong-1 generation 4-pin battery cases. If your battery case uses a 5-pin connector instead, see our 5-pin base mount plate. If you suspect the fault is electrical rather than mechanical, our battery diagnostic service can confirm before you buy parts.
Every Base Mount Plate purchased from All4eBikes is covered by a 12-month warranty against manufacturing defects, alongside a 30-day return window.
Send us a photo of your battery case’s base and we’ll confirm pin count and cradle shape before you order.
