More information about DuraTrax Onyx 255 AC/DC Dual Charger with Balancing DTXP4255

This is the Duratrax Onyx 255 AC/DC dual charger with balancer. If you can own only one charger, it should be the Onyx 255. It can peak charge a 15-cell NiCd at the same time its balance charging a 6S LiPo—and do both anytime and anywhere there's AC or DC power. Push-buttons let you program up to 10 battery charging routines for easy reuse and reverse backlit LCD lets you easily view eight types of pack/cell data and safety alerts even when lighting conditions are at their worst.



  • Duratrax Onyx 255 AC/DC dual charger
  • DC power lead with Alligator clips
  • Two Banana to Star Plugs
  • Two Banana to Standard
  • Two 2-6S balancing boards with JST XH connectors
  • Instruction manual





Note: Charge rates up to 6A, plus the ability to charge 1-15 nickel-based or 1-6S lithium cells make the Onyx 255 a match for any charging need. Dual outputs make it an especially good choice for models that use two packs simultaneously and modelers who run and recharge multiple batteries in a single session. Both outputs can peak charge NiCd/NiMH cells and balance 2-6S lithium packs for maximum voltage. Separate jacks make it as useful for radio packs as power packs. Simple menus, push-button controls, and a backlit, reversed LCD make it easy to use anytime, in any lighting anywhere there’s AC or DC power.
