LiFePO4 is a very safe technology, with no spontaneous combustion, fire and explosion.The self discharge rate is very low. There is no memory effect – the cells can be recharged at any state of discharge.
|We suggest to use the cells in parallel to achieve higher capacity, i.e. 100 Ah (2 cells), 150 Ah (3 cells), 200 Ah (4 cells)|
Take a look at using the long and short connectors for EX-L50.
The following chart shows the discharging capacity test. Even the Discharging current 0.5 C, 4 C, in voltage range 3.58 V - 2.5 V.

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 100 Ah cell is 50 A.
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.

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.
