|Charger||Odyssey OMAX 25A -1B|
Individual charger-monitor per battery.
|DC/DC Converter||Sevcon 622/11086|
72/80 300W. This unit drops out for 330ms if the input voltage drops below 60V. To prevent this I have set the Zilla to limit the batrtery voltage sag to 63V.
|Top Speed||52 MPH (83 KPH)|
Speed limited by gear ration and batterhy voltage
|Acceleration||Limited by voltage sag. Congtroller limit set to 63V to prevent DC-DC dropout. |

I've noticed a reduction in range when th eweather gets cold, below 50F here in AZ.

|There is no instrumentation or on board battery charger. I occasionally connect up my laptop to the Zilla and dosome data logging. I have been commuting to work for 16 months as of 12/3/08. Charging time is about 2.5 hours. Normal commute round trip of 13.5 miles draws the batteries down to 55-60% SOC according to the battery charger/monitor. The longer 22 mile round trip gets them down to 40% SOC. The Zilla controller starts backing off on power when the battery voltage gets to about 50V. I can really feal this on the long round trip when it is cold now that the batteries are gong on 2 years, one is a year older and I think it is the culpriate for the loss of performance......I might add another battery, 7 total, to compensate.|
