i want to make a picture tracing light box/board and i was planning to use batteries to power it instead of a dc power adapter and i need to know what is a good battery that wont fry the strip.

 

you need to know what voltage and current the led strip needs, then choose a battery with the capacity that will last.

 

oh yeah lol, sorry. http://www.ebay.ca/itm/371305992754?_trksid=p2057872.m2749.l2649&var=640425017958&ssPageName=STRK:MEBIDX:IT
They're 12 volts, and i ordered 5050 strip 2 quantities of 1 meter.

 

12V @ 1.2 to 5amp, a Sla type battery would work, need to work out how long you want to use it in a continuous time, then get the amphour to suit.

several sizes available

like i said i want make a light box/board to trace with, so maybe a couple(2) hours for sure if possible more.

 

looks like the leds take 1.2amp per strip, so 2.5amps total, for two hours is a 5ah battery, go for a 7ah 12v battery.

 

ok i'll look for some thanks, um btw is this too much http://www.be-electronics.com/product_p/mn21.htm
or this one too

Not even close to enough..
Those are only 18mAh (thats milliamp hours).. You need 7aH (thats amp hours)
1mA = .001 amps

You need something like this

oh yeah sorry lol, didn't see the "m" on mAh.
Anyway isn't there anything more portable i can get.

 

reduce the leds, or power consumption and then you can use a smaller battery.

 

oh yeah ok then, i was thinking of cutting sections and putting a little bit of wire in between each section of 3 led's possibly reducing some led's. About 1"-2" of wire

 

what about a power bank?

 

You could use something like this http://www.hobbyking.com/hobbyking/store/__9184__Turnigy_5000mAh_3S_20C_Lipo_Pack.html
Lithium Polymer (Lipo) batteries will be the lightest you will find for your application and they come in all different shapes and sizes.They can be a little pricey though and they need a quality charger to go with them. You would need a 3s Lipo which just means it has 3 separate 3.7 volt batteries inside it. They are labeled 11.1 but when they are fully charged they are 12.6 volts, which
is right around what your bulbs need. And remember you can always run multiple smaller batteries in a parallel configuration which will raise your amperage but your voltage will not be affected.

i'm still looking for something like this...
but what if i took apart a dc adapter or other power supply, is there anything i can get

 

this is just a what if... but what if i wired several of these together batteries together. http://www.thesource.ca/estore/Product.aspx?language=en-CA&catalog=Online&category=Specialty Batteries&product=2300471
or if i connect mobile phone batteries together

 

No and No! You need gobs of current and small batteries will not give you gobs of current for any length of time.

Why cant you use an AC power supply? Is portability the issue?

Yeah i know i'll have to use an AC power supply, it's just that its nice when people have things that are portable... you know right.
Is this good or too low Amps http://www.be-electronics.com/product_p/68-121a-1.htm

 

no good, its only 1amp rated, if your going with a psu, try a laptop psu, they give out 5 amps and are ready available.
