£9.99
Bare 4-pin blade-contact connector spare for Hailong 01/02/03 battery bases — for repairing worn or corroded contacts, not a replacement for the full mounting rail. Not compatible with Hailong 01 Pro’s 5-blade connector.
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.
Bare connector-block pair · 4 blade contacts · ~20–25A · For repairing an existing base or pack
A bare pair of connector blocks — the female receptacle and matching male header — for repairing or rebuilding the internal connector inside a Hailong-family battery case or its base mount, without replacing the whole rail or assembly. Useful for a custom pack build too.
Fits Hailong 01/02/03-family battery cases using 4-pin blade contacts — not the Hailong 01 Pro, which uses a visually similar but non-interchangeable 5-blade connector. If you need the complete mounting rail and lead rather than a bare spare, see our 4-pin base mount plate.
Every Connector 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’s connector and we’ll confirm whether you need this spare or the full base plate.
