You can buy an external power supply for 6V 3A with the correct plug and polarity. inside pin is positive.

can I get a 6V external charger, which I can directly connect to the robot and use it in the place of the battery? I don't want to use the battery any more. I just want to charge it using the external power supply. can I do that?

you can use the robot while charging. This is preferred to do motion programming. If the battery is completely drain, you'll need to charge the battery for some minutes first. Certain pose may draw 3A current for the 20 servos, the battery will supply current in addition to the 1.5A from the power supply. This approach can provide programming for a few hours.

Can I use Robophilo while charging it or do I need to charge first and then use it? I want to use it for some experiments, which takes long time. What can I do?

Curiousity killed the cat, so I grabbed my trusty micrometer and took some measurements.......

Stock Philo pack cells are 1.19 in. long in the wrapper, the pack itself is 1.12 in. wide(two cells across).

The 6.0v 5cell 2/3A reciever pack cells are 1.10 in long in the wrapper.

Now remember I have two seperate packs from two different suppliers (one 1000mah and one 1600mah) that are just about the same size. Could be they're not 2/3A cells, but they are certainly easy to get.

I must be doing something wrong. Once he is all tuned up do you save to the file on your computer, then reload those settings onto Philo himself? if that is true then, ,my bad.

The 1000mah pack, I charged with the included charger. I would think it will charge the larger pack, but I have not tried that yet.

I have also used a hobby type charger on all my packs. That seems to extend the run-time on any battery you use. However when you unplug the battery you must reload the fine tuning as philo seems to 'forget' that stuff when the battery is disconnected.

can you use the standard charger with this battery pack?

the charger that comes with the kit is only rated at 1000mah I think.

Yes, I believe they are 2/3a cells. They seem to be slightly shorter than the cells in the original pack. I went to my LHS and got a second pack that was 1600mah, and that fit too. All I had to do is add the zip tie to hold it in. It is just an off the shelf pack, nothing special about it really.

Nice... Looks like a tight fit. Are those 2/3A cells?
I can barely fit the 2/3AA cells in his chest with the cells horizontal, the way you've installed yours and the 2/3A cells are a bit longer.

volts are calculated by the number of cells.
1 cell = 1.2 volts
5 cells = 6 volts
I would have a battery assembled in the same configuration as the stock battery with the same number of cells (5).
