Description

The JBD (Jiabaida) 14S 40A BMS is a protection board for 14-series NMC lithium-ion packs (51.8V nominal / 58.8V full charge). It monitors each cell and protects the pack against overcharge, over-discharge, overcurrent, short circuit and over-temperature, while balancing cells during charging. With charge and discharge on a common port and a 40A continuous rating, it suits 52V e-bike, e-scooter and energy storage pack builds.

Key Features

  • 14S NMC Support – Built for 14 Li-Ion (NMC) cells in series; 51.8V nominal, 58.8V full charge
  • 40A Continuous Current – Rated 40A continuous for both charge and discharge
  • Common Port Design – Charge and discharge through the same terminals for simpler wiring
  • Cell Balancing – Equalises cell voltages during charging to extend pack life
  • Complete Protection – Overcharge, over-discharge, overcurrent, short circuit and over-temperature
  • Low Internal Resistance – Low MOSFET circuit resistance for minimal heat and voltage drop
  • Low Standby Drain – Very low quiescent consumption protects stored packs
  • Wide Operating Range – Works from -20°C to 75°C
