I am considering buying a 17 DOF kit from China, its ready with brackets.
This kit can be used with 17 servos.

Thanks for pointing that out! Thanks both!
I have been reading me up on this subject now for 1 month. My approach now will to buy the shell from
Alibaba and by luck I found an article about EZ.
Wish me luck:)
Next question: should I buy my robot kit complete with servos or not.
The ez-bv4 can handle 5A continuous current draw total, up to 20A spiked current. Servos do not actually draw all that much current until they are stalled or a number of them are being used at the exact same time. In most applications of 24 servos all the servos are not being moved at the same time.
I will get the kit with the servos and build it from there.
Now I need to find a good power source. In the sales post they state I have to buy a "HM battery X 1" because they can't ship it.
I guess they think about "MH" battery.
@Leaderone You should buy a lipo or niMh for your power needs...
I don't think you'll burn the main fuse drawing 5amps, since it is a 20amp fuse...
Here's the manual for the ezb4 EZB4 Data sheet
Once I tripped the poly fuse (because of 5 locked servos), my ezb did not reset (I was using a 10amp niMh D cell pack)... All that happened was the ezb4 stopped responding... servos would not move nor did the digital ports respond... Powering it off for a few minutes reset the poly fuse and all was normal after that...
I suspect the issue might be the brand HDservo. I have never used that brand and have have no experience with them. I'm guessing they draw quite a bit of current which Anthony's power supply, wiring, or connectors possibly cannot handle and it's browning out the ez-b.
I could be mistaken but If we could get a sample servo I could do some tests.
If you were to do a lot of movement, you might want to power off of an external power source. I have not had the issue you are having with any of my 8 ez-b v4's. To be fair, one of them has the servos being powered from a different supply due to brown out issues I was having and to provide some components with 5v, some with 6v and some with 7v. The side effect of this is that it allows me to power the devices off of multiple battery packs, but I haven't had the poly fuse flip on me an any of the robots.
The difference is that switching power supplies, or even linear voltage regulators, have a very hard time meeting the burst current demands of multiple servos which is often over 10Amps. This was one of the largest reasons we are now using LiPo batteries connected directly to the servos (Fuse protected of course) as opposed to using voltage regulators.
For my inMoov project I am looking at a 60 or 100amp power supply....
