FDK (formerly Sanyo) AA 2000 Twicell (formerly Eneloop) TX pack made to fit Hitec's new Aurora 9 and the Airtronics SD-10G. Excellent way to go when replacing a weak factory pack. 7.2 volts and 6 cells just more capacity. Comes without plug, choose below or reuse your old plug. Although these are advertised as charged and ready to go right out of the package, we recommend a forming charge period prior to use. Our tests have shown them be factory charged to 60% or less. Twicell (Formerly known as Eneloop) NiMH cells have a lower daily self discharge than typical NiMH cells.
Break in (first forming charge) for 2000mah pack on 50mah charger - 54 hours, 70mah charger - 40 hours. Individual Cell Internal Impedance 96.0Ω
Although Sanyo's website shows Cx1 (capacity x 1) fast charge rates with a NiMH rated charger, I'm not prepared to warranty any packs damaged by fast charging or peak charging in any form. If you insist on experimenting with fast charging and damage a pack, call Sanyo, not Radical RC.
