# VECTRIX POWER!!

You know,...thinking about this, what if I went behind the head light to grab the higher amp circuit to backfeed outside power of 12v power into the system feeding at a low volt, but helping the amps for distance,...and maybe have a refreshing affect on helping the front first out cell that everyone keeps talking about that fails. I would think that I would have to go back before the switching at the feed of the 12v, so it will be not after the headlamp command.

The VECTRIX D.C. converter, that supplies 12 volts to the headlights and other low voltage items, is ONE WAY, and cannot be used to feed external 12 volts back into the VECTRIX 125 volt battery! (This converter takes the 150 to 100 volts or thereabouts voltage of the VECTRIX battery, and converts it to 12 to 14 volts for the low-voltage lights and other needs.) A D.C. source of around 150 volts, with a means to control charging current, is required to fully charge a VECTRIX battery.

However what could be done is remove the 12v DC-DC converter from the system, and run all the 12v Auxilliary stuff off their own 12v battery. Would leave a little more juice from the main pack for distance.

### Re: VECTRIX POWER!!

The truth is: The VECTRIX DC/DC converter, takes its INPUT from the entire 125 volt battery, and converts it to a (Nominal) 12 volts DC, at about ten times the current drawn from the 125 volt battery, and this lower voltage, higher current powers the 12 volt VECTRIX items. (Example: ONE amp at 125 volts gives about TEN amps at 12 volts)--Applying 12 to 14 volts DC at this converters load teminals will NOT reverse the converter and "Charge the 125 volt Vextrix battery"!--If your Vectrix will travel 50 mph for 1/2 hour, you would cover 25 miles, and if, during this trip, the 12 volt load was 6 amperes (72 watts) you would use LESS than 1/2 ampere-hour of capacity from the Vectrix 125 volt battery, as the current drawn at 125 volts would be near 0.6 to 0.7amperes, for 1/2 hour (0.3 to 0.35 AH/ or about 1/100th of the battery capacity.) Switching this load on, off, or supplying it from another battery would make very little difference in your range! --Bob Curry
