Hi,

I want to know how to check the max charge current for battery pack (Series+Parallel). Now my battery is litium ion battery. max charge current is 6.8A (1C) for single. Now I connected 12 batteries in 2S6P and I want to charge it. But I don't know whether I need to consider for the whole pack (40 Ah) or max charge current for single cell (6.8A).
how to set up the charging current in battery charger.
Please kindly advice me.

Thanks

The charging current in any cell should not exceed that recommended by the manufacturer. In the case of a pack of cells be aware that several cells packed together will not dissipate heat as easily as when each cell is free-standing and the temperature of each cell should be considered, and the charge current adjusted if needed. As always, consult the datasheet.
