Power to the Super Rebound





Introduction: Power to the Super Rebound

Some days ago I bought a Tyco Super Rebound at eBay. The Super Rebound is a toy, it's a remote controlled car driven by a rechargable battery.

The car is really fun. But because the car is used and the batteries are old, the capacity of the batteries do not last long. I needed to recharge often. I thought about buying a new battery pack. The thing is that the battery pack is very special. I got a shock seeing the prices, around 29,-$. I took a look at the batteries and found out that these things are poor nicad types. The capacity is rather low and nicad batteries are likely to have the memory effect. Then I took a look at the charger ... oh no, it was one of those cheap and simple constant current chargers. These beasts kill the batteries!

So I decided to buy some nimh batteries with mre than 2500mAh capacity. More as twice the capacity of the original ones. To keep the batteries in good shape I also bought a charger that works with delta voltage charging. Using this charger it is possible to charge the batteries in short time without destroying them.

You need:
- soldering iron
- cutter
- proxxon (or dremel)
- glue

BTW. the "Reading Man" is one of my greatest supporters! He always knows how to do things and he tells me .. ;-)

Step 1: Removing the Old Cells

First of all you needed to break the plastic case of the battery pack. I don't like to dremel .. I like to proxxon .. ;-)
Cut the case along the side and cut deep enough so that you can see the cells inside. Do only cut the main plastic case not the cut the hinges. Because you can not cut the case complete the rest has to be done by putting a screwdriver in the slit and break the case. Be careful but steady ;-)
Take out the batteries and remove the wires.

Step 2: Preparing the New Battery Pack

Now solder the new battery pack. Soldering of batteries is not the easiest task. Be shure not to put to much heat on them. Batteries don't like that. Use short soldering time, work slowly and let the batteries cool down.

All batteries need to be put in series. We like to get 7.2 V out of six batteries with 1.2 V each.
Put attention to the polarity of the batteries and the connectors. On the plastic case you can see a small + and a small -.
The new batteries fit exactly into the case. I used AA size batteries, NIMH with 2700 mAh capacity and 1.2 V cell voltage.

After putting everything back into the case, close it. Pay attention to the small guiding slids!
Fix it with glue.

Step 3: Modifying the Charger

As you can see in the picture, the charger is a really cheap module. A real batter killer! The only thing that is worthy is the case, because the special battery pack for the Super Rebound fits exactly into it.

To be shure that no one ever puts the charger into the power socket ... I cut of the pins. Now I can lay it on a table beside of the new charger.
I removed the cheap charging parts and soldered some wires on the contacts to connect the new charger.
The new charger is connected via a small power plug. On the picture you can see a test setup. I did not have a power plug by hand ...

After charging I put the new battery pack into the car and ... whow ... more power than ever!

    Anyone know the dimensions of the tyco 6v battery pack?

    Im aware that the batterys are 6 AA in series which would put the box at 14*14*70mm but I need to know the exact dimensions as Im trying to figure out what lipo battery will fit in the default compartment best. I want to restore this with better batteries which fit into the void.

    Hi anthonyprov,
    I didn't make a new or modify the old charger. I just made an adapter to use lipo accus with the rebound. Frickelkram modified the charger, so maybe he can answer your question...

    I have decided to modify my rebound for the use of lipo-accus - I've just modified an old rebound accu so that I could put a 2s 1300mah lipo in it. Works flawlessly.

    how much did it cost to make the charger for your tyco rc super rebound?

    @ralf-instructables and @frickelkram how much did it cost to make the charger for your tyco rc super rebound?

    I find this website quite good for batteries, chargers, radio equipment etc, very reasonably priced:
    Maplin is quite good for most things (not radio equipment)but can be a little expensive
    rc tanks fan

    By the way ... is someone out there who added white LEDs to the car? I try to add the LEDs so that the "light" goes on while driving forward (whatever direction forward is ... ;-). Think of what to do if the car turned upside down ... is there a need to add a sensor that can detect where actually "forward" is ??? Then add another pair of white LEDs and use these as front lights? ). After adding the white ones it would be nice to add red ones in case of stopping the car ... brake lights :-) After that also yellow ones could be added to show the direction in case of driving in circles ... ohhh I should'nt think of that ... there seems to be no end ... ;-)

    if you havent found a solution yet, get some of those cheap glass lightbulbs from cheap dolar store toys. they look like small glass bulbs and can have voltage run in either direction so they would be perfect for attaching to the motor directly. you may need a resistor though.

    I have one of these cars too.  Unfortunately, I lost the remote.  Any advice on how to get that project off the ground would be good.

    Buy another RC tank, rip the control circuits out and transplant them...

    That, or look for someone selling just the remote. These usually used only one or possibly two different frequencies (that's why you could never race your friends with the same kind of car), so buying another one would probably work.
