Charging A123 M1 Cells?

[starscream]

The "Dapter" cuts the connection to the charger when the cuttoff voltage is reached. Yes, you have to manually count the number of blinks per cell. I don't find it hard to count to 6 though :005:
Counting blinks beats the $200 price tag for the Xtrema, especially when I have never used the cells before. If I invest more into the M1's, I'll reconsider the Xtrema.
My multimeter typically shows my 6S pack at 20v when the "Dapter" cuts the charge. Thats 92.5% capcity in 16 minutes at 7.5 AMPS. I can live with that for now. I sent my Xtrema back because I couldn't justify keeping it when the $40 LipoDapter charges my packs just fine.
