Initial, first time charging

LiFePO4 chargers

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 300Ah cell is 150A.
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.

Balancing and protection

Important part of each battery pack is balancing and protection electronic. Most frequent solution is BMS123 Smart. This Advanced solution for battery monitoring and management of LiFePO4 cells support Bluetooth connection with your phone, iPad, tablet or other device. Free Android and iOS application included.

Connecting the cells

Winston produce cells with easy to assemble square shape, terminals are made for screws allowing simple installation with spanner.

Interconnection between cells is important part of any battery pack. Original copper connectors are made of several thin layers for ideal flexibility and conductivity.
Make sure to clean oxidation from both, terminals and connectors (with Sandpaper or similar) before assembly. Oxided contacts may have very high resistance and cause unbalancing of the battery.

Plastic caps are cheap solution to prevent unwanted shortcuts and for easy plus and minus marking (red and black colors are available).
