Two-cell A123 battery packs with a nominal voltage of 6.6V. All of our A123 packs are produced using genuine A123/LiFe cells from A123Systems.
When charging A123 battery packs comprised of two cells (2s) do not charge above 7.2V.
When using 2s A123 packs in your RC model, do not discharge below 4.0V, this will ensure a long service life for your battery pack.
These batteries make ideal receiver battery packs and a great replacement for 6-cell NiMH packs.
