9.6 in paralell-longer runtime?

[lykan]

If I hook up two 9.6 volt battery packs in parallel (nicad) Will the output still be 9.6 volts?

With my limited knowledge of electrcity it would seem that if you hooked them in paralell, it would cut the load on the batteries in half, and provide a longer runtime, and a cooler load on the batteries. Is my assumption right?

I think hooking them up in series would double the voltage and be disastrous.

Has anyone tryed hooking up ni-cads in paralell? What are the problems associated with it?

I wouldn't think it would be a problem. I guess the only downside would be more weight, mounting, and more batteries to charge.

I'd make sure to match the cells 1:1.

I could be wrong though.

 

[lykan]

I think I am going to try it out heh. I'll let you know how it works.

Hrmm maybe i'll wait for another response Hate to waste two good batts

no it will be cut in almost half!
be careful as I have done somethin similar and it fried my batteries!!

 

[lykan]

Did you hook them in parallel, or series? Tell me how you hooked them up.

*edit* I do plan on charging them seperately.

 

[jon2]

parallel and i shorted them out..so you can see how I F'd them up..lol

 

[lykan]

LOL, I'm not looking to short mine out. Just the positve to positve, and negative to negative.

I know car batteries are DC as well. To hook up an extra battery for my stereo equiptment all i did was run wires from one battery to the other just liek I am jump starting.

The voltage stays around 13.5 (same with one battery) the only difference is more stereo time with the truck off, and more cranking power.

I'm just wondering if there is anything different on a nicad

If you hook 2 9.6 volt packs in parallel, you will essentially double the pack's current capacity. But the voltage will stay the same. So you can feasibly run 2 packs in that way. Think of it as doubling the size of the gas tank.

If you hook them in series you're doubling the voltage. And you will most likely bake your electronics. I wouldn't recommend that.

Lycan, I think the answer is, NiCad are the same as any other batteries when it comes to connecting them.

You already know how to hook them up, so go nuts!

 

[lykan]

Right on, thanks as always Candyman I'm going to hook up some connectors tonight so I can charge individually, and run them together.

The cool thing about 9.6 er's is they are light. (the little aa packs) Just about any car that uses them can handle the extra weight no problem.

How about load? Since hey are in paralell will each battery essentially be providing half the power? If so I could possibly run a larger motot without heating up the packs.

Wish me luck.

 

[jon2]

If they already set up then you should be fine. if you are assembling them I would throw caution to the wind. Good luck buddy.

You're right. Half the power from each battery. Or more specifically, half the current from each battery. So you can run a larger motor without heating up the packs, but just make sure you esc can handle the larger motor too.

And for what its worth, I've run 2 packs in parallel in my rc vehicle with no problems. But I do recommend both packs being made with the same type of cells. Same brand, same # of cells, etc. And do charge them separately like you are already planning. I understand charging in parallel is not a good idea at all.
