Inspired Energy NC2040 & NC3040 Batteries

The NC2040 and NC3040 are 10.8V Lithium Ion Standard Smart Batteries from Inspired Energy. There are currently three models available, each with a different combination of Ampere-Hour capacity and discharge current / power capabiliy and regulatory certification.

  • NC2040 batteries are optimised for energy - i.e. long runtime at low to medium discharge current/power.
  • NC3040 batteries are optimised for power - i.e. shorter runtime but capable of discharging at higher levels of current/power.  

The list below provides the main specification details, click on a model number to go to the dedicated model page, download full technical information, view compatible chargers / accessories and purchase your battery on-line.

NC2040 NC3040 batteries contain three Lithium Ion 18650 sized cells in a 3-series, 1-parallel format. The embedded electronic fuel gauge features 'impedance tracking' technology which provides highly accurate state of charge prediction. The fuel gauge electronics also provide a protection function, preventing the battery from being over-charged, over-discharged, over-loaded or short circuited. The NC2040 NC3040 also include a redundant over-charge protection circuit for additional safety. The NC2040 NC3040 are fully SMBus (System management Bus) and SBS (Smart Battery System) compliant which means they are simple to integrate into your product.

NC2040 NC3040 batteries meet all current transportation testing regulations, are FCC / CE marked and are RoHS2 and REACH compliant.
