15S Battery
Monitor and
Balancer

The 15S Battery Cell Monitor & Balancer is a precision instrument that ensures multi-cell batteries are maintained in an optimal state, improving system reliability and prolonging battery life.

The 15S Battery Cell Monitor & Balancer does exactly as its name suggests: it monitors cells within a battery, and it balances those cells if and when they require it. Compre-hensive data detailing the battery’s internal state is sent via the CAN interface.

Features

  • Transforms a “dumb” battery into a smart (self-balancing) battery
  • Supports multiple battery chemistries – LiPo, LiS and LiFe
  • Supports 9 to 15S batteries
  • Galvanically isolated 80 Amp current sensor
  • External current sensor input for > 80A
  • CAN interface provides control and monitoring of voltages, currents, temperatures
  • Battery temperature monitoring with up to 3 external sensors
  • “Heat” / “Cool” control outputs for temperature regulation
  • User-friendly configuration software
  • Rich variety of balancing control options
  • Seamless integration with our Generator Control Unit
  • Weight: TBA
  • PCB dimensions: 62 x 72mm

Usage

The Battery Balancer is intended to be connected to a battery, installed into a UAV and interfaced to the vehicle’s CAN bus. A pair of indicator lights on the front panel give a “go / no go” indication of the battery’s state of balance and state of charge. More detailed battery information is available via the CAN bus.

Use of the battery balancer confers a number of operational advantages:

  • Batteries do not need to be removed periodically to check for balance
  • Battery status is available instantly, either directly from the front-panel LEDs, or remotely from the telemetry data sent on the CAN bus
  • Batteries are maintained in a state of balance, improving flight-readiness
