I have a project to decorate the family "Little Red Wagon" with
Christmas lights. So I stated experimenting with LED light strings and
battery combinations. *I finally decided to use an Inverter and not
cut up any light strings. *The LED light set that I found has 80
lights and the specs state it uses 12 watts. *So as a test I connected
two 6v lantern batteries in series and ran the leads to the inverter
(rated at 100watts), connected a lamp with 40 watt bulb.

The inverted started up and seemed to be working, but when I connected
the lamp, the green led on the inverter turned to red and lamp glowed
at 60% of what it should. The voltage from the battery dropped from
12.6 to 11.5v. *I need a battery with less internal resistance.

What would make a better 12v source ? *Most NiCad drill batteries are
up around 18v+
What is the voltage of battery in APC backups ?

Your family has one of these?

Holy crap! That one always filled the park at National Speedway on Long
Island in the 60's & 70's. *Funny Cars, The Green Monster, Big Daddy Don
Garlits, talk about popping memory bubbles.



Just run the inverter off of the truck's battery.

Do you mean on Sunday Sunday Sunday at National Speedway?

I grew up in Queens during the 60's & 70's.

Well, "grew up" would be stretching things a bit.
