Description
Overview
XT30U extension and adaptor leads made from 18AWG silicone wire and rated at 15A. One end carries an XT30U connector with upgraded gold-plated terminals; the other end is either a matching XT30U connector or bare tinned leads for soldering. The set covers five configurations and five lengths, so you can extend, convert or tap into an existing battery lead without cutting the original plugs off.
Specifications
- Connector: XT30U male / female, upgraded gold-plated terminals
- Wire: 18AWG silicone rubber, high temperature resistant (marked 200°C)
- Rated current: 15A
- Available lengths: 10cm / 20cm / 30cm / 50cm / 1m
- Available configurations:
- Female head — XT30U female connector + bare tinned leads
- Male head — XT30U male connector + bare tinned leads
- Male to female — XT30U male on one end, female on the other
- Male to male — XT30U male on both ends
- Female to female — XT30U female on both ends
- Wire colours: red (positive) and black (negative)
- Housing: yellow flame-retardant nylon
Purpose
It solves three common problems in one part: reaching a battery that sits too far from the ESC, joining two leads that use the same gender, and providing a solderable pigtail where a device has no connector of its own. Because it is a pre-made lead, the original battery or ESC connectors stay untouched.
Applications
- RC cars, boats and aircraft — LiPo battery to ESC connection
- Drones and multirotors — power distribution and battery leads
- Lithium battery packs and charging harnesses
- DIY electronics that need an XT30U pigtail soldered to a board
- Bench testing batteries and small power equipment
How to Use
- Decide which connector you need on each end, then pick the matching configuration — the “head” versions give you bare leads on one side.
- For head versions, strip and tin the bare leads if needed, then solder them to your board or device and insulate with heat-shrink tubing.
- Observe polarity: red is positive, black is negative. Reversing the leads will damage the ESC or the device.
- Plug the XT30U connectors fully home until they seat firmly — a partially inserted connector will heat up under load.
- Keep the continuous current within 15A, which is the rating of both the connector and the 18AWG wire.
- Check the connectors periodically for heat discolouration, especially after high-current runs.
- Connector Model: XT30U Male / Female, upgraded gold-plated XT30U terminals
- Wire Spec: 18AWG high temperature resistant silicone wire, rated current 15A
- Optional Cable Length: 10cm / 20cm / 30cm / 50cm / 1m
- Plug Material: Flame-retardant nylon housing, gold-plated copper pins, low resistance, anti-oxidation
- Wire Core: Multi-strand flexible silicone wire, bend-resistant, wide temperature range
- Structure: XT30U connector on one end, tinned bare wire on the other end for easy soldering
- Feature: Anti-reverse polarity design, locking connection for small-current lithium power supply
- Used as lead wire for lithium battery packs, power connection between battery, ESC and charger.
- XT30U male/female plug for quick plug & play; tinned bare wire for soldering to PCB or power modules.
- Gold-plated terminals ensure good conductivity. Silicone wire supports stable 15A continuous current and high temperature resistance.
- Multiple lengths available to fit different internal wiring layouts of equipment.
