Product details
A 3S JST-XH balance lead extension cable designed to bridge the gap between your 3S LiPo or Li-ion battery and your charger, parallel board, or voltage checker. Ideal for drone builders charging packs inside protective enclosures where standard factory balance leads fall short, this cable eliminates awkward positioning and prevents mechanical strain on your battery's internal solder joints.
Key features
- Connects a 4-pin JST-XH male plug to a 4-pin JST-XH female socket for 3S battery charging and individual cell balancing.
- Removes tension and bending fatigue from the battery's factory balance wires during repetitive charging setup.
- Acts as a sacrificial wear adapter, protecting costly battery packs from the pin wear caused by daily insertion and removal cycles.
- Fully compatible with all standard FPV smart chargers, parallel charging boards, and field cell checkers using the JST-XH balance format.
Specifications
- Connector type: JST-XH Male to JST-XH Female
- Pin count: 4 pins
- Supported battery configuration: 3S LiPo, LiHV, and Li-ion packs (11.1 V / 11.4 V nominal)
- Length: 10 cm or 20 cm (choose the variant)
- Wire: silicone insulated; 20 AWG on the 10 cm version, 22 AWG on the 20 cm version
Essential for safe FPV charging workflows, this extension lets you keep your batteries securely sealed inside fire-retardant LiPo safe bags while your charger and power supply remain easily accessible on the workbench.
