I need help. I'm trying to solve this comm issue for my son and keep striking out. I copied and pasted as much info as I've collected, but basically it connects and then disconnects if I try to do anything. It seems as the ezb4 forces the connection to close, but the computer connection still shows the connection active.

Well i will have to look for another charger tomorrow. We were hoping to do it on battery power, we didn't realize it had to be plugged in.
Kind of defeats the purpose if we have to be close to a wall outlet.
If you have 2 batteries, you could connect them together in parallel. That would double the amperage. 2 - 7.4 volt 1300 mAh batteries connected in parallel would give you 7.4 volts and 2600 mAhs. (2.6 amps).
I recommend to use a LiPo Robot Battery 7.4v 1300mAh with a LiPo Battery Harness, which will drive upwards of 16 servos. Power consumption is a physical law governing the universe and not a limitation of ezrobot products
. it may get in the way, but it's something we all must face. Thankfully ezrobot provided a solution with the LiPo Robot Battery 7.4v 1300mAh combined with a LiPo Battery Harness that accompanies the developer kit.
You will not easily find a plugin adapter that will power more than 1 or 2 servos max. Do not even try to find a plugin adapter to suit the needs of your robots power requirements because wall worts aren't designed to provide that much current to electromechanical devices (motors). Use a LiPo Robot Battery 7.4v 1300mAh. Also there is an adapter needed to connect the LiPo Robot Battery 7.4v 1300mAh directly to the EZ-B v4/2 Wi-Fi Robot Controller. The adapter is LiPo Battery Harness.
Either way, a LiPo Robot Battery 7.4v 1300mAh with LiPo Battery Harness is the best bang to cover all power requirements - if using ezrobot servos.
The LiPo Robot Battery 7.4v 1300mAh with LiPo Battery Harness will most likely damage other manufacturer servos because they're generally designed for a 5v max, which is prettt much impossible to find in a battery. only use ezrobot servos with EZ-B v4/2 Wi-Fi Robot Controller
I tried the 6 battery pack that comes with the developers kit, it looks nothing like the LiPo battery. Using the included battery holder did not work either. I have a power supply capable of providing around 8.3 volts at around 2 amps but dont feel comfortable pluging it in to the EZ B. We will have to wait for the battery in order to proceed. Thanks for the help.
Just to make sure did anyone have a chance to review the script. I just want to rule out any programing issues.
The 6 AA battery pack is great for small projects with expirementing using the developer kit. It doesn't have enough juice for more than 2 or 3 servos. The 8.3v 2 am power supply will not have enough juice either. 2 Amps is barely enough for one servo.
The LiPo Robot Battery 7.4v 1300mAh will provide up to 25 Amps
It's the battery used in revolution robots. It will be perfect for your use. Remember to get the LiPo Battery Harness as well! That makes it easy to connect to the Power Shell
@DJ
It seems like we answer this question at least once a week. I would suggest increasing the dev kit cost and just including a LiPo, charger, and harness, or at least moving them up in the "related items" tab when you view the dev kit in the store. Maybe even prompt shoppers to add them to the the order like Amazon does with their "people who pirchased this often also ordered" prompt.

It's been considered - and the related items does exist but should be more prominent during checkout. Although that only solves ezrobot customers, not resellers.
Price cannot be altered and the product cannot be changed without a new sku/product due to registered msrp agreeements.
Something will happen if issues rise above 2% of sale volume. That's the threshold to consider change.
I didn't think about the re-sellers, although you could provide them guidance, no way of enforcing without a new sku. Even on the related items tab, it could be more prominent. It is at the bottom rather than top of the list -- just saying.
Just curious, and you don't need to share if this is considered proprietary, but what percentage of your sales are direct vs re-seller?
Good to know you have a planAlan
