Six-cell A123 battery packs with a nominal voltage of 19.8V. All of our A123 packs are produced using genuine A123 LiFePO4 cells from A123 Systems.
When charging A123 battery packs comprised of six cells in series (6s) do not charge above 21.6V.
When using 6s A123 packs in your RC model, do not discharge below 12.0V, this will ensure a long service life.
Each pack is fitted with a JST-PQ type balance tap, which has the same pin-spacing as JST-XH but the housing is slightly different with a clip on the top.
