This is a male-side WMB battery connector plug set from EG4, used to terminate or repair the battery-side wiring on compatible EG4 battery systems.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Battery connectors are a small part with an outsized job: every amp your system draws passes through this junction. A mismatched or poorly seated connector is a common source of resistance-related heat buildup at the battery terminal. This WMB male plug set is intended for EG4 battery systems that use the WMB connector standard — confirm your battery's connector type against manufacturer documentation before you order, since connector standards are not interchangeable across brands.
- Connector type: WMB male plug (mating female connector sold separately)
- Color: Black
- Intended use: Battery-side connection point on compatible EG4 battery systems
- Does NOT include the female counterpart connector — order both halves for a complete connection
- NOT confirmed compatible with battery brands or connector families outside the WMB standard [NEEDS VERIFICATION]
- Wire gauge, pin ampacity rating, and crimp specifications: [NEEDS VERIFICATION] — not provided in current manufacturer data
Battery connectors like this one see repeated mate/unmate cycles over the life of a system, and every cycle is a chance for the pins to seat slightly off-center — a loose or misaligned WMB connection raises contact resistance and generates localized heat under load. Prevent this by inspecting the pin alignment and seating each connector fully until you feel the positive lock, rather than relying on wire tension to hold it in place. Verify a solid connection with a multimeter (resistance check across the mated pair) before energizing the circuit. This aligns with standard practice under NEC guidance on maintaining low-resistance connections at current-carrying joints — a connector running warm to the touch under normal load is a sign to disconnect and re-seat it, not to keep monitoring it.
- Male half only — designed to mate specifically with the WMB female connector
- Black housing for visual polarity/color coding at the battery terminal
- Manufactured under the EG4 brand for use with compatible EG4 battery hardware
- Straightforward drop-in replacement for a damaged or worn existing WMB male plug

FAQ
Is this the male or female half of the connector set?
This listing is the male plug half of the WMB connector set. You'll need the matching female connector to complete a connection.
What color is this connector?
This plug is black.
Will this fit any EG4 battery, or only specific models?
It is designed for EG4 battery systems using the WMB connector standard. Confirm your specific battery model uses a WMB-style connector before ordering. Manufacturer documentation in the Resources tab can confirm exact fitment for your model.
Does this include wire or is it just the connector housing/pins?
Wire gauge, pin, and crimp details are not specified in the available data for this listing [NEEDS VERIFICATION]. Check the Resources tab for the manufacturer's full spec sheet before you plan a termination job around it.
Warranty & Registration: Manufacturer warranty terms for this connector are not included in the current product data [NEEDS VERIFICATION].
