1. Introduction
Congratulations for purchasing TME's Xtrema Lithium (Li) Charger
–
Wattmeter. You are now
the owner of the most expandable, high end Li charging and monitoring system available. The
Xtrema combines the power of a high end Li charger with the versatility of a high end Wattmeter.
It also features a very useful temperature probe for monitoring your batteries and motor as well
as an over sized LCD display that shows all important data simultaneously. And the Xtrema has
an expansion port that allows for future plug in features and FREE lifetime software updates.
Our promise to you is to keep the Xtrema current with the latest Lithium advances and charger
features. This assures you that Xtrema is a solid value for many years to come. Your unit is fully
calibrated and tested during manufacturing and should provide many years of trouble free
operation.
Safety while charging is an integral part of the design of the Xtrema and a high priority at TME.
Two collective features actively prevent overcharging your battery. They serve as backup to the
normal constant voltage termination. The temperature cutoff provides the first level of protection.
It is set to shut off your charger if your battery goes over 104°F. This default temperature is
easily changeable to accommodate ambient temperature or for a more conservative cutoff. The
second method is a safety timer that aborts the charge if it takes longer than 120 minutes. This
default time can also be changed to match your charge rate.
Most people find that they can easily operate the Xtrema with no manual or with very little
information. However we recommend that you take the time to read this manual to discover
features, tips, and options that may not be immediately obvious.
