Duratrax Onyx 245 AC/DC Dual Charger

This is the DuraTrax Onyx 245 AC/DC Dual Charger with LiPo Balancing (DTXP4245)

The Onyx 245 charger handles all of these batteries; LiPo, LiFe, NiCd, NiMH with built-in balancing that maximizes the safety, longevity and performance of your cells. Its dual charging capability can keep bashers in action whose vehicles require two batteries for operation — as well as racers running in two classes that need to charge both receiver or race packs at the same time.

Two independent outputs both with balancing and lithium-capable! 

LiPo, LiFe, NiCd, NiMH...the Onyx 245 charger handles all of these batteries, with built-in balancing that maximizes their safety, longevity and performance. Its dual charging capability can keep bashers in action whose vehicles require two batteries for operation — as well as competitors running in two classes who need to charge both receiver or race packs.


  • Charges 1-3 cell LiPo and LiFe (3.7-11.1V) and 4-8 cell NiCd and NiMH batteries
  • Both outputs are compatible with LiPo, LiFe, NiMH and NiCd batteries and the Onyx 245 can charge two batteries of the same or different chemistries simultaneously
  • Each output includes a jack for charging transmitter packs and 4-5 cell receiver packs
  • Advanced LCD display with backlight
  • FIVE YEAR warranty through Hobby Services (U.S.A and Canada only) beginning at date of purchase


The Onyx 245 is two chargers in one. Identical twin outputs make this an excellent choice for models that use two battery packs — and for modelers who rotate through multiple batteries at home or at the track.

A built-in balancer for each port ensures optimal charging of lithium packs, including LiPos and LiFe cells such as LiFeSource packs. AC/DC flexibility, an advanced LCD with backlight, and simple menus and controls make it easy to use anytime, anywhere, by anyone.

Compact, lightweight, powerful and versatile, the Duratrax Onyx 245 gives racers yet another advantage on race day!
