Title: Different Batterys Per System
Post by: ReplicatorBuilder on October 08, 2007, 01:21:34 PM
For parts that need great power and need to work if the other parts go dead should i use seperate batterys on them

thanks

no, if another part goes dead that doesn't mean the battery it's attached to is dead to. So you can still use that battery with all other systems attached to it.

And if you need alot of power, just buy one big battery pack, that's cheaper than two or three smaller ones that have the same power combined.
Plus one part may use more power than the other, causing one of your smaller packs to be be depleted sooner than the others, thus limiting your operation time.

i beieve rebelgium is saying is to have one main battery pack which supplies power to all the systems so that you wont have to go checking and charging each individual battery pack

That is a good suggestion to do. Have a main battery( or batteries)  giving 12V out @ whatever amperage there is. Then use voltage dividers or regulators or transformers to provide power to each other system.

I believe Replicator is saying that he doesn't want the entire robot to die simply because he doesn't have power to move the motors..

IE, he still wants it to send out video, regardless of motor battery life.

In which case, yes seperate batteries are the way to go.  If you do use just 1 big battery once it dies, your done.  Also it can be electrically noisy to use just one battery.  On occasions even, when the big 20a motors(or whatever your using) hit on to max.. it could cause such a voltage drop it may reset your computer brain..

Of course if you do use a big one, simply attach proper sized capacitors to all of the motors(which shoudl have some anyways), and also to the brain.  So that huge voltage drops won't effect it as often..
