4S 14.8V LiPo 5-Pin Balance Adapter (TY1 HS3911)  [HS3911]

5-pin balance lead adapter for 4S packs

The TY1 HS3911 adaptor links a 4S 14.8V LiPo battery's balance port to a charger's 5-pin balance input, providing a neat connection for balance charging and per-cell voltage monitoring. It is intended for hobby chargers that accept separate balance leads rather than replacing any main power leads or safety circuitry.

Installation is straightforward: with the charger switched off, attach the adaptor to the battery balance plug, then insert the adaptor into the charger's balance socket. Double-check that the charger is configured for LiPo and set to 4S prior to starting a charge cycle. This piece only transmits the balance tap signals and is not a substitute for proper main leads.

For workshop use the adaptor is handy for quick cell scans and routine balancing during battery maintenance. Inspect connectors regularly for corrosion or bent pins and follow the charger manufacturer's safety recommendations.
