This is the DuraTrax Onyx 245 AC/DC Dual Charger. LiPo, LiFe, NiCd, NiMH...the Onyx 245 charger handles all of these batteries, 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.

Features:
  • Compatible with LiPo, LiFe, NiMH and NiCd batteries.
  • Output adapters for ALL the connectors drivers use most!
  • 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!
  • Can charge two batteries of different chemistries simultaneously — from NiMH to LiPo to LiFeSource™ Lithium Iron Phosphate (LiFe).
  • Each output includes built-in balancing for up to 3S LiPo/Li-Ion/LiFe batteries plus a built-in radio battery charge jack.
  • 5 Year Limited Warranty (U.S.A. and Canada only)
Special Features:
  • Two independent outputs, each with identical features and functions.
  • Each output includes built-in balancing for 2-3S lithium packs (both outputs).
  • Each output includes a built-in jack for charging 4-5 cell receiver packs and even transmitter packs!
  • A small, lightweight, built-in AC power supply is great for cramped pit spaces and easy portability.
  • Each output offers selectable charge currents of 800mA, 1.5A, 3A and 5 amps.
  • Each output includes a backup safety timer which automatically stops charge to prevent accidental battery overcharge.
  • Includes Deans® Ultra Plug®, Traxxas®, and standard connector adapters for each output.
  • Includes ElectriFly® and FlightPower®/Thunder Power™ 6S balance boards.
  • Solid-state reverse polarity and current overload protection ensure trouble-free operation.
  • A DC power lead with alligator clips easily connects to many 12V DC power sources

Very nice charger for beginners or just someone looking to charge and balance two separate batteries. Although it is a very basic charger. It still is very very nice for the price. Things I have found lacking are a discharge feature, and the ability to input many of the batteries settings, such as customizable charge amps. It uses four preset instead of selecting the correct 1C charge rate that is recommended. fortunately most of my batteries are 5000MAh so the preset 5amps is perfect. but for my bigger batteries i have to undercharge then, which certainly will not harm them. Also, the balance feature of this charger is nice no batteries have drifted yet. All in all a very nice charger for the price point. this time choosing the cheaper route will not lead to disappointment

Absolutely amazing!! Best charger yet. Charges both batts. at 5amps with no problems. I love how it tells you the voltage of the batteries this way you know about how much longer the charge will take. If your thinking about buying this go for it.

Just thought I'd update my previous review. I was able to send the charge back to Duratrax and have it repaired.. However I had to buy another charger in order to continue racing.. Now charger is back we have used it for 1 race day cycling roughly 10 batteries thru it at 5amps on each side.. Charger worked as it should, however not going to give it full stars due to the hassle... If you're on a budget I'd recommend buying just be aware that the over heating is a common issue, but repairable if sent in..

This is a great basic charger. It is easy to use and will charge all of the common types of batteries. There are few things that need to be considered before you buy this charger though: 1) Only charger up to 3S batteries (1/8th scale guys need to be aware of this) 2) Some of the supplied charging leads use some really small wires. They work fine or have so far but I would have at least seen some 12GA wire at least on the deans plug 3) Does not store battery settings like most of the other chargers 4) Has limited charging rates (preset numbers: 1, 1.5, 3, and 5 I think) I almost always use 5 because I use 7.4V 5000mAh batteries I would buy this charger again because I was aware of all these things before I bought it so I was not surprised when I got it. For the money, you cannot beat having a charger capable of charging 2 batteries at up to 5amps a piece.
