Hi,
What problem with my EZB4? When I start to run few heavy duty servo (4pcs), it is running normally. But It will auto restart when I add more servo (up to 8pcs)! Anyone can help to answer what problem with my EZB4 and any solutions?
Thanks your attention!

That is a simple answer. You are not providing enough power for the servos. Servos use electricity, the more servos you add, the more electricity is needed. If you do not provide enough electricity for the servos, the circuit will fail.
Use a better battery. What battery are you using? I recommend using a LiPo Robot Battery 7.4v 1300mAh combined with LiPo Battery Harness
You have a power problem... or more precisely lack of it... Use a 7.4v lipo or 7.2V nimh battery... If that doesn't help, then you are drawing too much power from the ezb... The ezb4 can only supply 5 amps continuous and 20amps in brief spikes.... If your servos are drawing more power than 5amps continuous then the poly fuse on the ezb may trip causing it to reboot
Good Morning DJ and Richard,
Thanks for your reply. I have used AC adaptor for the EZB4( last time DJ suggested me). So, what can I do to give more power to servo when it running and safety to work with EZB4?
Thanks for your help! Ricky Ma
What voltage is the adapter? How many amps is it rated for? You really should use Lipo batteries for projects that require many servos....
Here is my adaptor photo
Thanks
You have started a few conversations in the past regarding power adapters.
https://synthiam.com/Community/Questions/6301 In this thread, a low amperage power adapter was discussed and advice was given for more amperage
https://synthiam.com/Community/Questions/6163 In this thread i recommended a 6 amp power supply. Can you verify that you're using a 6 amp power supply? That may not be enough for the number of servos which you wish to run, which is 8.
In tests to use JD with an AC Adapter, we use a power supply of 20 amps. That robot uses 12 servos. The challenge with using an AC adapter is that you're limited because AC adapters are not generally designed for motors, at least 8 motors. Also, in order to achieve a high number of amps, 220 volt mains is required.
@Ricky.
In addition to what DJ and RR have mentioned above , I also suggest that you take a look at the tutorial and the end of this post, specifically, the amps, batteries and power supplies sections. This should help guide you to in to finding the correct power source for your robot and reduce the chances of running in to problems in the future.

Hi DJ,
Thanks for your reply! Yes, I used your suggestion AC adapter with 6amp power supply!
In this case, Is it I need to use others AC adapter with 20amps? If yes, I will buy one to try.
Actually, my human robotic will be finished in coming January 2016. Now, just how to use EZB4 program and solve the power problems!
Besides, I want to say EZB4 is really help to success my dream my work. And I don't mind to spent time and money to finish my robotics. In future, I will introduce EZB4 to Hong Kong because it is really good product for anyone!
Cheers! Ricky Ma
