Onyx 245

AC/DC Dual Balancing Charger

Onyx™ 245 AC/DC Dual Charger with Balancing Radio Control Car Action 2014 Readers' Choice Charger of the Year!
5 Year Warranty

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.


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!
