hi Zerover, my battery say 1800 mah but i think not have more than 1200 or less, i'm trying to find your model in a local or European shop.

a lot of thanks for your information, i don`t have wall charger and today its very dificult to find :-(

...

yes, i need buy a good solder and chek again, i'm charging with the original charger.

Since power is power no matter what the source, you can use any type of battery as long as you are comfortable with how the robot performs. As far as optimum performance, there are certain things I considered when choosing how to replace the original pack:

Weight--although I-Cybie is a quadraped, balance and timing are needed to execute an efficient walk (for an I-Cybie). The batteries should be about the same size and weight as the original.

Size--The battery pack must fit within the compartment with little or no modification to the robot--because I am lazy and I don't want to perform a complex modification for every robot I use.

Power--the battery pack must perform as good or much better than the original.

Availability--I do not want to be at the mercy of a single company to get my batteries. I want them to be inexpensive and I want them quickly.

The best battery that I have found to meet those qualifications is a 10 cell 12 volt battery pack made by combining two readily available and inexpensive 5 cell 6 V battery packs. The only tools I need to make this type of pack are electrical tape and a soldering gun. Because the resulting pack is slightly longer than the original, care must be taken during construction to make it as short as possible so that I need not modify the battery compartment. The only modification I have to make to the robot is removing the small retaining clip in the battery compartment--and that is a reversable process. To assist in removing the battery because it will be a tight fit even after taking the precaution of shortening the overall length, I use a bit of twine wrapped around the pack to create a "puller" and a little lithium grease for lubrication.

Tonino, I don't know why your original pack failed but it was not because of the design. The circuit diagram works, hopefully the batteries work in the way they were designed. As you know, unplugging and plugging in an I-Cybie battery is often a violent affair. Sometimes the plug sticks, or a wire is pinched or crimped. Sometimes the plug itself is defective or worn and the pins don't seat properly. In addition, if your solder points are not solid or they are positioned where they are repeatedly flexed during the process of plugging/unpluggin the battery, then the solder point will eventually fail. I-Cybie will not run if it does not continuously receive both the 6 and 12 Volts it was designed to accept. Experimentation is necessary to find the best way to route the connecting wires. I have found that having the connector originate at the center of the pack allows for the least amount of stress to the solder points.

hello, what do you think about this kind of batterys?

http://www.amazon.com/PowerGenix-ZRPGX-AA8-High-Voltage-Rechargeable-Batterie..

with 4 have 6,4V and with 8 12,8 V, the only thing is test if can put 8 normal battery inside and will be a good option for us.

The problems associated with your choice of those particular batteries is connecting the individual batteries. If you have the equipment to weld (not solder) to the endcaps of the batteries then you are lucky. Welding together batteries--even with the proper equipment is potentially dangerous. You cannot solder to this type of battery. Also, standard batteries have a extrusion at one end--a nipple if you will. This increases the length of the battery and makes the overall pack less likely to fit without extensive modification to the battery compartment--and we are talking disassembling the robot and cutting out an end wall of the battery compartment type modification. That's a lot of work to make a battery fit.

I think you can easily get it at general robotic thread in this forum. I have seen there, so I tell you. I hope that it would be useful for you.
