Jan 17, 2011 No Comments by

As battery Technology continues to develop and evolve, so should your chargers. The new Onyx 235 is extremely versatile and is ideal for your needs for a portable (and affordable) field charger. The Onyx 235 is all the charger you’ll need for power and radio packs.  It also features cell balancing for up to 4 Li-Po, Li-lon or Li-Fe cells. I can also peak charge up to 10 NiCds or Ni-MHs cells and includes 5 connectors/adapters.

I can charge at up to 4C for lithium packs and at 8A maximum.

Includes output adapters for standard, Traxxas and Deans Ultra Plug connectors, plus ElectriFly and FlightPower/Thunder Power balancing boards.

Features 3 special-purpose jacks for added versatility:

·         Universal radio (for charging transmitter and receiver packs)

·         USB (for trackside cell phone and accessory charging)

·         Mini USB (for downloading firmware updates)

The AC and DC power cords reduce clutter but leave power options open. Balances lithium cells with +/- 5mV accuracy – and ensures maximum voltage in each one. Features push buttons and audible cues for simple setup – and 10 battery memories for instant recall and customized results. Protects packs with an automatic safety timer – and itself with reverse polarity and current overload circuitry.


·         Battery Types:  1-10 NiCd or NiMH (1.2-12.OV) 1-4 LiPo, Lilon or LiFe (3.7-14.8V)

·         Fast Charge Currents:  0.1-8.0A linear, adjustable 4C limit for lithiums
