High quality 20Ah special cell (battery) GWL/Power based on lithium iron technology - LiFePO4 allows 3C discharge continous current and 10C max. current. The cell is in metal housing for high energy density (98.5Wh/kg).



The tiny dimensions (178x71x28) and weight only 0.65 Kg makes this cell suitable for EV and lightweight applications as well as for energy storage.

Main advantages of the ZG-LFP020AH

  • Supports high speed discharge (3C, 60A)
  • Provides high currents at peak discharge (10C, 200A)
  • High quality of production for long lifespan (over 2000 cycles at 80% DoD with 80% residual capacity)
  • Narrow tolerance of the specifications
  • Metallic housing (case)
  • Cells are provided with nuts for easy connecting

Hint: we suggest to use the cells in parallel to achieve higher capacity, i.e. 40Ah (2 cells), 60Ah (3 cells), 80Ah (4 cells)

Technical information

  • Nominal voltage 3.2 V, operational voltage is 2.8 V - 3.65 V
  • The maximum charging voltage for initial charge 3.8 V
  • Recommended subsequent charging is to 3.65 V
  • The minimum voltage is 2.6 V
  • Maximum discharge current is 3C continuously
  • Peak discharge current is 10C (for 15 seconds)
  • Operating temperature -25°C up to 50°C (discharging)





The following chart show the discharging capacity test. Even the Discharging current 3C (60A) the cells have capacity still over the 20Ah - 20.83Ah in voltage range 3.65V - 2.8V and 21.34Ah in voltage range 3.65 - 2.5V!

Application notes
These battery cells are suitable for all traction applications including, electric bikes and scooters. They support high current discharge rates. The cells can also be used for the stationary applications - such as energy storage and solar applications. The self discharge rate is very low. There is no memory effect – the cells can be recharged at any state of discharge. LiFePO4 is a very safe technology, with no spontaneous combustion, fire and explosion.

Important: Always follow the guidelines in the USER MANUAL.




Operational instructions:

  • All goods is supplied as new, directly from the manufacturer
  • Before the first use, always charge the cells to full voltage
  • The initial charge must be done with low current at max 0.5C - i.e. 10A for 20Ah cell
  • Protect the cell terminals against dirt, damage and short-circuit
  • The cells must be monitored and protected against deep discharge and over charge
  • The charge and discharge must be carried under supervision

Initial, first time charging


Cells are precharged from manufacturer to conservation charge (usually 30-50%).
The cells have to be charged with low current before the first use.
The first charge should not exceed 0.5 C - eg for 100Ah cell is 50A.
FAQ: Initial charging information

For initial charging of multiple cells, connect them in parallel and the charger outputs should be connected to both ends of the parallel rows of cells, exactly as it is described here:
FAQ: The initial charging of the number of cells

We recommend to use chargers specially made for LiFePO4 cells First charge and initial balancing of the whole pack is important step towards long lifetime.

Alternatively you can use regulated (Laboratory) Power supply as initial charge tool. Short description how to proceed.
