Non-Military Drone, Robot, or RC 2S1P Battery Management Solution Reference Design


Design files


This reference design is for a 2S1P battery management solution (BMS) for non-military drone, robot or radio controlled (RC) projects and designs. Quickly add gauging, protection, balancing and charging to any new design for a non-military drone, robot or RC product or use this reference design to add advanced features to an existing design. This design will get you up and testing advanced battery management features quickly and easily.

  • Compensated end-of-discharge voltage (CEDV) gas gauge accurately measures available charge in li-ion and li-polymer batteries
  • Integrated cell balancing while charging
  • Programmable protection features for voltage, current, temperature, charge timeout, CHG/DSG FETS and AFE
  • Diagnostic lifetime data monitor and black box recorder for your battery
  • On-board 3.3-V/5-V 500-mA regulator to run an external controller

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
