This is the DuraTrax Onyx 235 AC/DC Advanced Balancing Charger. Built on the proven features of the Onyx 230, the Onyx 235 balances each cell for maximum voltage and longer life! There are a lot of chargers out there. But there’s only one that started with the design of R/C Car Action’s 2010 Readers’ Choice Award winner — and went it one better: the Onyx 235. The Onyx 235 improves on the features of the proven 230 with balancing and other extras drivers have asked for. These additions make the model 235 the most versatile Onyx charger yet and a great buy for every modeler.

TYPICAL APPLICATION:
The Model 235 is the most versatile Onyx charger to date. With charge rates of 0.1-8A, it's the right choice for nitro and electric cars and boats, as well as transmitter and receiver packs. It peak charges up to 10 NiCd or NiMH cells, balances and charges up to 4 lithium cells (including LiFeSource™ LiFe packs) and includes adapters for the five most common battery connectors. In addition to radio battery and balancing jacks, the Onyx 235 also includes a USB jack for charging cell phones, music players and other accessories at the track, plus a mini USB jack for downloading firmware. Detachable AC and DC power cords, a backlit LCD visible under all lighting conditions and a 5-year warranty round out its impressive performance options and protection.

Features:

  • Charges the 5 most popular kinds of power packs: NiCds, NiMHs, LiPo, LiIon and LiFeSource™ LiFe packs.
  • Includes output adapters for standard, Traxxas® High-Current and Deans® Ultra Plug® connectors, plus ElectriFly® and FlightPower®/Thunder Power balancing boards.
  • Balances and charges up to 4 LiPo, LiIon and LiFe cells and peak charges up to 10 cell NiCd and NiMH cells.
  • Charges all packs at up to 8A — and lithium packs at up to 4C!
  • Detachable AC and DC cords reduce tabletop 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.
  • Built-in fan kicks in automatically, to keep heat down and performance high.   

Features special-purpose jacks for added versatility:

  • Universal radio jack (for charging radio packs)
  • Balancing jack (for lithium-based packs)
  • USB jack (for charging cell phones, MP3 players and other small electronics)
  • Mini USB jack (for downloading firmware updates)

Great charger for the price. It's perfect for my bashing and rock crawling needs. Very easy to set up and has an easy to read display. The 10 batt memory is awesome, and comes with all the basic charge and balance leads. I have been (ab)using this charger for a while with no problems. It is my second Duratrax charger, and I will certainly recommend them to others.

I purchased this bundled together with an RC used. I knew nothing about the charger, I was just told it would work. In the last 6 months I have found that I love this charger. I never once read the manual (I am new to this hobby) and have been able to figure out how to setup a battery profile and then charge. Very easy to use and seems to be built very well.
