I just received the beta version of the new TME Xtrema Lithium
Charger/Wattmeter. It allows you to set the charge cut off voltage to 3.6
volts/cell for A123 M1 packs. I've only had it on the bench for an hour so
can't tell you much more.
Here are the specs found at: http://www.tmenet.com/xtrema.htm
a.. Charges 1 to 10 Cell Lithium Batteries at up to 8 Amps
b.. Includes battery temperature sensor with programmable limits for extra
safety!
c.. Temp probe attaches easily with unique Velcro® strap!
d.. Programmable safety timer feature.
e.. Battery memory stores your favorite pack settings.
f.. NO need to calculate volts or amps, simply enter cell count and mah
rating!
g.. Volts per cell is programmable at 4.2V, 4.15V, 4.1V etc. to let you
choose between maximum power charge or conservative charge to lengthen
battery life!
h.. Unique Safe Storage Charge mode at 3.7volts/cell for Safe Long term
LiPo storage!
i.. Special 3.6 volt per cell for m1 Hypersonic Lithium Ion cells from
A123 Systems
j.. 10.5 to 15 Volt input range perfect for the field!
And a wattmeter feature is also included;
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? 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 optimize motor performance while
measuring, testing, and matching your components.
a.. Large 4 x 20 LCD simultaneously displays:
b.. Volts - up to 60 Volts
c.. Amps - up to 100 amps peak (50 amps continuous)
d.. Watts - up to 6000 peak watts (3000 watts continuous)
e.. Temperature up to 300 deg F connects to motor or battery while
measuring watts!
f.. Horsepower - up to 8.1 Hp peak (4 Hp continuous)
g.. Alternate display records: Peak Amps, Voltage minimum (droop), Peak
Temperature, Calculated Watts and Hp from min Voltage and Current Peak
And it is made in the USA! This one is one to watch, it is going to be a
winner form what I have seen so far.
