More than just a high powered programmable charger, the Xtrema is a useful wattmeter than can be used to solve cutoff and overheating problems out at the field. You won\\\\\\\'t believe how handy a tool this is. Not only that, but with the included expansion port, the Xtrema becomes much more!. With a FREE download of our powerful XtremaLog program, the Xtrema\\\\\\\'s usefulness expands to include charge and power analyzer features via an optional data cable and your computer. Here is a screen capture of the XtremaLog output displaying a graph of a 10s1p \\\\\\\"m1\\\\\\\" pack that was charged.
Have you ever tried to use a wattmeter to study a new motor/battery setup and realized you had to write down a bunch of changing numbers while you ran up your motor to see if your system was in spec?
|Click on the image to enlarge|
With the XtremaLog program used as a power analyzer, you can let your computer log the numbers and analyze your results later! The dual superimposed display lets you compare your performance to a previous run for more powerful analysis!
What's more exciting is that the same data cable can be used to download FREE FLASH updates from the Internet as new features get added. For example the XtremaLog feature is a FREE update. How is that for a good deal? The expansion port will not stop there. A future balancer will also plug into the expansion port as well as other future options.
The included Wattmeter is an indispensable tool for testing and troubleshooting your models' setup. It is critical to check each new setup to make sure there are no surprises. The temperature probe provides a safe and reliable method of shutting down the charger should one of your cells go bad. Plus it can be used to monitor ESC, Motor or battery temperature while using the wattmeter!
Big Display means much easier operation.
Remember when computer radios first came out? They were awesome but programming them required an open manual in one hand or a great memory to remember all those cryptic parameters. Today\\\\\\\'s computer radios are much easier to program. Why? Well as most have noticed the displays have gotten larger so the functions are written much clearer and the options are not buried under menu after menu. So what do we see with most chargers on the market?. The displays are small and navigating through menus is cumbersome.
The next generation charger, the Xtrema, eliminates this problem with a big over-sized display.It features an extra large 4 line x 20 character LCD that displays all important data simultaneously! Also features ultra-simple, easy-to-navigate, intuitive menus with simple UP DOWN RIGHT LEFT joystick navigation! Feels more like web browsing than operating a sophisticated charger.
So when we say the Xtrema is super easy to use, we don't mean easy like the other charger manufacturers like to hype! We mean REALl easy straight forward and logical. Lets just say intuitive. Instead of being scared you will burn up your expensive lithium cells you feel confident your settings are correct.
Xtrema BALANCE CHARGING SYSTEM
Included with the new Xtrema Charger model XTR-LWMXG are two Xtrema Lithium Balancers ( XTR-BAL) capable of stand alone and direct computer controlled operation along with theXtrema Balancer Interface Module (XTR-BIM) bringing fully integrated balancing to the Xtrema Lithium Charger in a way no one else does. This conbo supports balancing for up to 10s cells. However the optically isolated interface can be expanded to support two more balancers to provide up to 4 optically isolated balancing connections! This means you can simultaneously balance up to 4 series or 4 parallel balancer plugs connected to separate balancers but charged as one giant pack! The isolation makes connecting balancers WORRY FREE since there is no way to get dangerous shorts if the sequence or polarity is wrong. Yet another TME first! Bringing the most sophisticated and flexible integrated balancing system to high end Lithium chargers on the market.
Future Proof vs Planned Obsolescence
If you have been following electric powered RC equipment for awhile you know that change is inevitable. Everyone is tired of the cost of upgrading equipment. It seems that no sooner you make the commitment and purchase a hobby item, new technology soon makes it obsolete.
The next generation charger, the Xtrema, was the first charger to eliminate this problem with FREE lifetime updates and ample power and capacity for your needs now and in the future. When the Xtrema first came out it was designed for conventional Lithium-Ion, Lithium Polymer and Lithium Manganese technologies. At that time a new and emerging battery technology LiFe Lithium Nano-Phosphate (commonly known as the \\\\\\\"M1\\\\\\\" batteries from A123 Systems) was entering the market. Within weeks we had written and beta tested an update to accommodate the new voltages associated with these new cells. This made TME the first in the US to support the new Lithium nano-Phosphate M1 batteries from A123 Systems. All our customers instantly had access to the update via the web or by simply returning their unit for a free upgrade. Our competition was months behind and with no web support.
The cost of upgrading equipment is also dependent upon how durable the item is. That is why the Xtrema Charger / Wattmeter carries a 3 year warranty. We have over-specified key components to make this a hard working durable tool. And we have so much faith in our design and workmanship that we offer a 3 year warranty. You get a quality unit built using rugged Surface Mount technology to ISO 9001:2000 quality specifications and designed, manufactured, tested and supported right here in the USA.
Our Future Options include::
- FREE lifetime software updates! Either send it back or update it yourself with the optional data cable.
- and more features to be announced!
Please note that our specifications are truthful when comparing them to cheep import chargers on the market. We specify continuous OUTPUT POWER instead of peak INPUT POWER. Thaalso t means we don't start at a higher power and fall back to a lower power when our circuitry gets hot. Also we meet the FULL specification on a standard 12 volts automotive battery and do not require you to have an expensive 17+ volt power supply or dual 12V batteries to acheive full specs! So please be digilent when comparing specifications.

Our wattmeter has features not found anywhere else! Like simultaneous display of the standard current, volts and watts along with temperature and horsepower displays!. The large LCD allows us to do this and the temperature probe functions to monitor motor or battery temp while you are testing. Peaks are also being recorded and are displayed in a separate window.
Why do you need a wattmeter? On a new installation it is critical! It helps you determine if you are stressing or damaging your electric motor or battery with the prop / load you have placed on it. Can your battery actually hold up to the demands you place? Are you on the verge of burning out your motor? Do you have a short in your motor? Out of balance battery? Is your cutoff on your speed controller working properly? To summarize you need it to verify and optimize motor performance while measuring, testing, and matching your components. Solve your problems before it\\\\\\\'s too late!
