Stand alone charger questions

bigboi24 · Post by **bigboi24** » Thu Jan 10, 2008 11:54 pm

Hey, everyone. I made my self a stand alone charger because I was bored and I had an extra controller. So it uses 4 AAA bat's. I was wondering I I could hook up a DC? or which ever charger that plugs into the wall to charger it. I have a wall charger that outputs 4.8 volts and then 180 mA. Is that good? would I jsut be able to hook up the wires to the pos. and neg. side of the battery plates?
Here are some pictures of it.

And those blue batteries seem to not work. They are Ni-Cd 350 MAh 1.2v
They ar from my AEP airsoft gun

4.8v 180 mah is perfect for charging a 2.4v battery. I use a 300mah one and it gets the batteries done in 2-3 minutes. So I'm guessing that'll warm your battery in about 5 minutes.

I striped the cables and everything, but It won't charge. Dunno why. Anyone know why?

You've probably already checked but just to start with the obvious...make sure the polarity (+ and - ) are right. If they're backwards it'll just roach the batteries. I cant think of anthing else to check before that (other than that the wall charger is working)

Yeah, I already checked that.
This is what I was doing:

Am I supposed to do this? connect every plate?

EDIT: Opps, forogt to resize them

Update:
Ok, so I'm not gonna use the adaptor I mentioned before. So now I'm Stuck w/ 2 other adaptors. I got a 7.2 V 250 mA and then a 4.9VDC 450 mA. Are any of these good? the 4.9 VDC is a cell phone charger.

def go with the 4.9v it should charger your batts in just a few min, plug it straight up pos to neg.

Well, none Of them seem to work

What;s wrong?

if there not working your not doing something right.

take the pos directly from the wall adapter and the neg directly from it, put it directly on the car's pos and neg. it WILL work. if not, time to buy some new batterys.

yeahn I tried that already.

Well, i guess I'll jsut buy some rechargable AAA batteries and charger for them.

if the wall adapter wont charge it, aaa Ni-mh's def wont make a difference.

? really? I mean it chargers on the controller. just not on the stand alone charger

There's a circuit board in between the battery terminals and the charging tabs for the car. If the power coming into it is different than it's expecting, sometimes it won't work. Here's what I would recommend:

and just substitute your controller for my Motorworks base, and it should work.

Take the controller apart and find where the battery power enters the circuit board. Solder some new wires to those locations and get a female jack (like a M or N at Radioshack), and add the corresponding male jack to the end of your adapter.

Oh jezz, that was kinda hard to understand.

So, All I do Is use the controller to charger it, just instead of bat.s its an adapter? I think i scrapped the contoller, let me check

If you connected the batteries this, we might have the problem.
