The first charge should not exceed 0.5 C - eg for 400Ah cell is 200A.
FAQ: Initial charging information

HINT! For initial charging multiple cells, must be connected 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

Please see practical examples of installing cells and recomended SBM protection of operation:
the Simple Battery Management.
Example of the 16 cells in series with protection module SBM16.



Check recommended accessories:
the terminal connectors.
Flexible terminal connector for safe connection of cells.


the terminal covers for the LFP cells.
They protect the terminals against dirt, damage and short-circuit.
