Anti‑Sparking Pre‑Charge Module for Heavy‑Duty UAV
Auxiliary Pre‑Charge Module for Heavy‑lift Cargo Drone Power Loop, prevent XT interface sparking & burning upon power‑on
1. Basic Specifications
Product Name: Anti‑Sparking Pre‑Charge Module for Heavy‑Duty UAV
Core Component: High‑power current‑limiting pre‑charge resistor
Connector: XT60 male & female plug
Wire Insulation: High‑voltage silicone wire
Outer Protection: Abrasion‑resistant braided sleeve, flame‑retardant heat‑shrink tube
Working Temperature Range: ‑20℃ ~ +85℃
Applicable Battery: 10S‑18S lithium battery pack
Applicable UAV Payload: 100‑200KG heavy‑duty drone
Pre‑charge Duration: 2‑8 seconds according to model

2. Key Performance Parameters
Function: Pre‑charge main‑loop capacitor before battery connection, eliminate instant large‑current sparking on XT power connectors
Safety Notice: Temporary auxiliary device only. Must remove module & restore original main power cable before flight mission. One module for single battery loop, parallel multi‑battery system requires independent module for each battery branch.
Resistor Tolerance: ±10%
Installation Requirement: Keep ≥2cm clearance for heat dissipation, do not attach resistor to carbon‑fiber or lithium‑ion battery surface.
3. Structural Features
Integrated wiring harness with XT60 plug‑and‑play structure.
Fully heat‑shrink sealed wiring terminals for complete insulation.
Separated pre‑charge port and main power port to avoid mis‑plug.
Compact harness layout, suitable for UAV internal routing & cable tie fixing.
4. Application Scope
Widely used for 100‑200KG heavy‑lift agricultural UAV, cargo transportation drone.
Suitable for high‑capacity multi‑cell lithium battery power system.
Solve spark, burn, adhesion risk of high‑current XT power interface caused by capacitor inrush current.
5. Customization Options
Custom resistor resistance value
Custom harness total length
Custom compatible connector types
Custom wire gauge
