@Nomad... what's your point? EZ Robot already ships lipos in all their robots. Why would it be any different if they added a Lipo to the developer's kit.... I have bought a few (larger) Lipos from eBay with no problems....

here in belgium they check lipo's 3 times. i like the idea of putting a lipo and charger in the kit.

It seems like I remember DJ saying that because the LIPOs were enclosed in the robot, they didn't have an issue shipping. There were some countries that would not allow the battery to be shipped loose in the box. I could have made that up but I think I remember seeing this a while back.

that is correct david.

Thanks guys I charged the batteries again and tried it with 2 servos it worked for like 1 minute until it discnnected but then I tried with 1 servo and it carried on for long I hooked up 3 servos and the camera it worked for a very little while before it disconnected but I think I'll need new batteries. Thanks Richard R for answering first

;) Hunter's robot ran great on 1350 Ni Cd rechargeable batteries. He is using continuous rotation servos. His robot ran prior, and recorded 4 videos after that. He gave it a good test following the red ball, many servos, and was using the 6 cell developer kit package. The 2500 rated batteries ran even longer. The battery charger said it takes 9 hours on the 1300 series batteries and 12 hours on the 2500 batteries. Make sure you charge them long enough, and keep similar rated batteries in the charger.

:D

NiCads produce more current than niMh.... But lets be honest here, the best batteries are NOT "AA"s no matter if they are niMh or NiCad... I recommend Lipos, Sub C Nimh or SLA... and in that order...

We all know that, but the Op was using rechargeable batteries for developer kit as instructed , and they work! Don't talk them down for a user unless you tried them. I think his issue was charging them.
