Well, an update... this battery system you folks helped me design has worked well... very well.. In fact it seems to be so good, that I suspect that it might carry on for the whole three days we need it, rather than recharging at night every day.
But, I don't want to take chances and be without...
Covers? Covers? You mean to guard against shorting out between the two?
Hmmm.. it would be nice if there was some sort of material I could heat shrink around the terminals like I did with the joins in the wire..
I'm gonna look for large diameter heat shrink stuff..
Thanks
Total cost?
Ammo Box $20.00
Spray Paint 5.00
Battery 50.00
Charger 45.00
Converter 40.00 (included $22 for shipping to Canada!)
Small parts 25.00
----------
Total 185.00
I could have got a power pack for somewhat less at the local Canadian Tire...
Ok, job done!
Thanks to you folks, I have a neat little portable power supply for my device. This will give me more flexibility in my work and make life easier. Thanks so much for all your help.
If you have any questions about the components I ended up using, or anything else about this...
"The time spent in reconnaissance is never wasted"...
I dunno who said it first, but it appeared several times in the books of one of my favorite authors, Ted Allbeury.
I've been mulling this whole project over in my head today and trying to come up with an idea for a suitable carrying case...
I cannot seem to make the link work for that page... the model number of the one I mean is PST-DC292.
Its the second or third one down the list.
Will that one work as well?
In looking at the converter, I see another one offered by the same supplier... will it do the job as well? I see that its switchable allowing me to use this unit for other devices.
Thanks

Ok, more questions...
If I put all these parts into a carrying box of some sort and hook them up together, will they conflict with each other?
The converter is wired to the battery, and so is the charger. Is there any risk of damage to the converter while charging? Is there any risk of damage...
It just occurred to me... is there any special need for ventilation for the battery, converter or charger?
In use, the battery and converter will be in a building at a trade show.... a convention center.
I see the battery is sealed, so I assume if I carry it at a shallow angle from time to...
Now you have me interested in building it from parts... I needed a project!
The battery you mentioned is the Panasonic P174-ND and weighs 14.3 lbs.
The converter only weighs 7 oz. and charger is 3 lbs, so all the parts, plus cables, etc will not exceed 20 - 25 lbs. I can lug that to where its...
Yes a 24 Ahr battery, and an inverter, and a battery charger will do the job. And, i'll probably end up with an off-the-shelf power pack.... my question was what size power pack should I get?
As for staying in 9 volts DC, that would be the most efficient, wouldn't it. The Roland site does not...
I am going to be buying a Roland CD-2e recorder and using it in locations where I cannot plug it in.
The tech specs of this unit tells me that it has a current draw of 540 mA, and when using batteries it takes 6 X LR6 (AA) type alkaline batteries - so 9 volts DC, right?
The specs also say I...
