Ready-to-use JST XH2.5 balance leads

This set provides ten pre-wired 3-pole JST XH2.5 connectors with 140 mm leads in assorted colours. They are intended for 2S 7.4 V LiPo packs in RC helicopters and similar models, letting you extend or replace balance connections without soldering.

Verify connector pitch and cell count

Confirm that your battery uses the 2.5 mm pitch XH series and a 3-pin balance plug matching a 2S configuration. The wire length is 140 mm, so measure the routing path in your airframe to ensure the leads reach the charger or flight controller without strain.

Lightweight plastic housings with colour-coded wires

Each lead weighs about 18 g for the full pack of ten, adding minimal mass to a helicopter build. The colourful insulation helps identify individual cells at a glance, while the male and female plugs included allow quick series or parallel hook-ups during field charging.
