    hey thats great man! Can you give me more specifications about it? If i guessed right, it's actually an inverter with a battery incorporated right? can it be used with windows software like normal computer ups ? how long does it take the computer to drain the battery?

    can you tell me where did you get it from?

    Why don't you just put the ups on a switch that simple that's how my ups is in my car just use a 30 or 50 amp relay on the power + side and that works sweeet!

    Cool

    Remove the UPS battery, and just connect it to a 12V source in the car instead. Do not parallel the small batteries with the large car battery. Bad things will result from voltage differences, etc.

    thanx aaron and radioman, i was going to connect the two batteries together ... but with a diode to stop the starter motor draining the ups battery, by not using the ups battery, i will save space, and can fit everything in one box.

    Instead, i will leave the ups switched on, and use a relay to switch power to the ups from the car battery.

    armoured: correct! i got it from ebay uk, try www.apc.com 4 more info... i got the apc back ups 400, btw

    i should have it going by sunday, i`ll let u know how it goes.

    thanx again
