HydriMax Ultra
Rechargeable Nickel-Metal Hydride Batteries (NiMH)
Hydrimax Ultra packs
Battery of choice for Greg Hahn - 2-time Top Gun champion!

With huge capacities of up to 2000mAh and 4200mAh, these new HydriMax Ultra rechargeable nickel-metal hydride (NiMH) packs deliver longer flight/run times than any batteries we have previously offered! And with NiMH packs now being more affordable than ever, you get more for your money. Choose from 4.8V and 6.0V flat and square receiver packs, and 9.6V square packs for transmitters.

  • Almost twice the capacity of NiCds — in cells of the same physical size!

  • Proven quality and dependability!

  • Ideal for any radio system — and perfect for power-hungry computer radios and digital servos.

  • No special charging equipment is necessary; use a standard 50mA radio charger for trickle-charging, or the Hobbico Quick Field Charger MkII (HCAP0290) or Accu-CycleTM Elite (HCAP0280) for safe, quick peak charging.

  • All with universal radio connector.

  • Eliminates the "memory effect" that is possible with NiCds.

  • More environmentally friendly, with no disposal restrictions.
