Yeah Racing Angle Type 4mm & 5mm Connector Plug WPT-0121

The Yeah Racing angle type 4mm & 5mm connector set (WPT-0121) is built for anyone wiring up battery or ESC leads and wanting a low profile finish. Unlike a standard straight bullet connector, this one sits at an angle, so leads route neatly over or around a battery instead of sticking straight up and getting caught or snagged.

The real flexibility here is interchangeable pins, the same connector body takes either a 4mm or 5mm bullet, so you're not stuck buying separate sets if you run mixed battery sizes across your fleet. Swapping between them is as simple as unscrewing one size and screwing in the other.

Gold plated, solid bullet contacts keep resistance low, which matters for minimising voltage drop and heat under load, and the plastic housing protects against accidental short circuits during wiring work. Coloured O-rings are included so you can mark positive and negative clearly once everything's soldered up.

Worth knowing before you order: Specification for this exact connector states it's rated for 2S/3S batteries.

Soldering is required to attach these to your leads, this isn't a plug and play connector, so factor that into your build if you don't already have suitable tools.

FEATURES
Angle type design for low-profile, tidy wiring routing
Interchangeable 4mm and 5mm bullet pins in one connector body
Gold plated, solid bullet contacts to reduce resistance
Plastic housing for short circuit protection during wiring work
Coloured O-rings included for positive/negative identification
Rated for 2S/3S batteries (per specification, see note below)

BENEFITS
Low profile angled design keeps leads tidy and out of the way of the battery
One connector covers both 4mm and 5mm, so you don't need separate sets for mixed battery sizes
Gold plated contacts help minimise voltage drop and heat under sustained load
Plastic housing reduces the risk of accidental shorts while you're wiring
Colour coded O-rings make polarity easy to identify at a glance once fitted
