ELERIX Lithium Cell LiFePO4 Prismatic 3.2V 50Ah - 4C

An industrial lithium cell with high energy density and a capacity of 50 Ah, based on safe LiFePO4 technology. The battery is made of high quality materials and contains no toxic chemicals, guaranteeing a long service life.

LiFePO4 is a very safe technology, without spontaneous combustion, fire and explosion. The self-discharge rate is very low. There is no memory effect - cells can be recharged in any state of discharge.
All ELERIX cells are thoroughly tested in Tier 1 factories prior to distribution, including during production and prior to shipment. The ELERIX brand is distinguished by the high quality of its cells, which are primarily Class A.

• Aluminium housing (case)
• High power up to 4C, 200 A discharge
• Provides high currents at peak discharge (5C, 250 A)
• 3000 cycles / 15 years lifetime
• No toxic chemicals
• Suitable for electric vehicles, energy storage, solar and light duty applications

Discharge Test
The following graph shows the discharge capacity test.

Operating Instructions

• Always charge the cells to full voltage before first use.
• Initial charging must be carried out at a low current of max. 0.5C - i.e. 25 A for a 50 Ah cell.
• Protect the cell terminals from dirt, damage and short circuits.
• Cells must be monitored and protected against deep discharge and overcharging.
• Charging and discharging must be supervised.

Initial charge
Cells are pre-charged by the manufacturer to a conservation charge (typically 30-50%). Cells should be charged at low current before first use. The first charge should not exceed 0.5 C - e.g. 25 A for a 50 Ah cell.
When charging multiple cells for the first time, connect them in parallel and the charger outputs should be connected to both ends of the parallel rows of cells.

We recommend using chargers specifically made for LiFePO4 cells. The first charge and initial balancing of the entire set is an important step in achieving long life.
Alternatively, you can use a regulated (laboratory) power supply as a tool for initial charging.
