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. The additions make the model 235 the most versatile Onyx charger yet and a great buy for every modeler.


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.
