CellShield Temperature Probe - Part No: 1072-052
A thermal sensor probe for use with the CellShield 1072-051. When using the thermal probe, CellShield alerts the user to temperature faults by flashing the red Temp light. The thermal probes are extremely thin, and can often be inserted between the innermost cells of the pack, where pack temperature is highest.

1. CellShield Lithium Cutoff (Ref: 1072-051)

CellShield Lithium Cutoff - Part No: 1072-051
CellShield is a low voltage cutoff device which provides cell-by-cell protection for lithium battery packs. By monitoring each cell individually, CellShield prevents individual cell overdischarge due to pack imbalance or cell variations.

CellShield provides a soft cutoff when the lowest voltage cell of the pack reaches the set minimum voltage. The minimum voltage is adjustable from 2.5v/cell to 3.5v/cell. This lets you set the proper cutoff voltage for your specific pack. For example, 8-10C cells typically use a 3.0v/cell cutoff, while 20C cells work better with a 3.2v/cell cutoff. CellShield’s cutoff voltage is set with an easy-to-use potentiometer. There are no programmers to buy or complicated programming procedures. With CellShield, you turn the arrow to the cutoff voltage you want and go fly.

LipoShield Intelligent Lithium Cutoff - Part No: 1072-050
LipoShield is a low voltage cutoff device which enables any ESC to be used with lithium battery packs. It installs easily between your receiver and ESC and provides a reliable 3.0V per cell soft cutoff to prevent over-discharge damage to your expensive lipo packs.

LipoShield is a soft cutoff, so it is appropriate for any plane, even 3D types. The soft cutoff gradually reduces power to the motor allowing you to make a controlled landing.

Xtrema Lithium Battery Charging System

More than just a 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.

Or 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?

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 TME website as new features get added. For example the XtremaLog feature is a FREE update. How is that for a good deal? The expansion port does not stop there, the balancer system also plugs 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!

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 charger 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.

Xtrema Lithium Charger & Wattmeter - Part No: 1072-010
The Xtrema Lithium Charger / Wattmeter from TME is the next generation lithium charger that sets a new standard for safe, simple operation while offering a virtual toolbox of capabilities.

More than just a charger the Xtrema is a useful wattmeter than can be used to solve cutoff and overheating problems out at the field. Not only that, but with the included expansion port, the Xtrema becomes much more with the optional USB lead (see 1072-011). 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 Lithium Nano-Phosphate (commonly known as the "M1" batteries from A123 Systems) was entering the market. Within weeks TME 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 using the USB lead.

Xtrema Multi-Cell Lithium Balancer - Part No: 1072-012
The Xtrema Lithium 6 cell balancer along with the optional Xtrema Balancer Interface Module (1072-013) brings fully integrated balancing to the Xtrema Lithium Charger in a way no one else does to maximum 24 cells. The optically isolated interface supports two balancers each and can be paired up 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.

Use a 6-cell balancer in stand alone mode to directly balance your packs. Use the optional USB lead (1072-011) to connect the balancer to a PC for many more facilities.
