Multiple cells (series/parallel) battery charger?

Amer,

If your packs are connected in parallel, it would still be consider as single cell. From charger perspective, it is charging a single cell battery with internal self balance. You mentioned that the pack has three cells, each with 2200mAh, so does that mean it is total of 3x2200mAhr capacity. However, you also said two 1100mAh cells in series, so I am not sure I understand your configuration. Please let me know what is your battery configuration precisely and I can recommend a suitable charger.

If the pack is built by two cells of 1100mAh, and its output voltage is 3.7V, then the two cells must be in parallel.

Thank you Sam for your explanation.

Indeed, the total capacity is 6600mAh, at 3.7 V.  

So it would be 6 cells in parallel?  If so, which charger can I use? If you have any other battery configuration that would allow me to have a capacity mentioned above, I am open to considering it. However, the size and shape of the battery is pretty much dictated by the enclosure that I am given and that is why I chose the packs that I did.

Thank you,

Amer,

What is the charging current or charge time requirements. For charging current conversion to charge time, a good rule of thumb would be BatteryCapacity / ChargingCurrent  * 1.5.

Sam

The charging time can be overnight... about 8 hrs.  So this makes the charging current about 1.2A?

Thank you for your input.
