Firmware features
Description of the Universal Charger features


The Universal Charger firmware is the natural evolution of the Advanced Charger. The Universal Charger will use the same hardware of the Advanced Charger (HV or not HV) changing only the PIC firmware. For new hardware development we do not recommend the manufacturing of the Advanced Charger but refer to the dedicated hardware developed for Universal Charger. It will fast charge/discharge this types of batteries:

1. Nickel Cadmium
2. Nickel Metal Hydride
3. Lithium Polymer
4. Sealed Lead Acid

Changing the charge maximum cell voltage and the discharge cutoff value this charger can charge and discharge also the Li-Ion cells and in general the Li-xx cells. With the same adjustement the user can manage the VRLA batteries (Valve regulated Leaded Acid - automotive batteries). The key points of this new firmware are the following:

  1. Accurate calibration to meet LiPo cells voltage and current measurement requirements
  2. The usage of the charger does not require the PC, software needed only for advanced users
  3. 12 battery pack profiles stored into the charger
  4. 17 different parameters per battery pack, 5 editable on-the-field, 12 by PC software
  5. Parameters editable on-the-field (directly on charger)
    • Battery pack chemistry
    • Battery pack capacity
    • Number of cells
    • Charge current
    • Discharge current
  6. Parameters editable off-line (via PC software)
    • Cell cutoff voltage (all types)
    • Cell delta peak voltage (NiCd and NiMh)
    • Cell maximum voltage in charge (LiPo and SLA)
    • Charge final current (LiPo and SLA)
    • Maximum pack capacity charge
  7. General charger parameters (via PC software)
    • Selection of battery profile
    • Maximum charge current
    • Maximum discharge current
    • Voltage and current calibration
    • Customizable "hello message"


Please refer to the user manual in the file section for more details.
