When I ordered my Exceed crawler, I asked the seller if my Sanyo Eneloop battery charger would charge the batteries. The answer was yes, but the first time I tried it, I am not so sure. Here's the charger:

Batteries are EMB NiMH 2200 mAh.

The reason I thought they were dying is the car would begin to backup on it's own if I left it idle for a few seconds. It would stop on it's own in a foot or two, or if I intervened with the remote. On cheaper RC cars I had, I remember this being due to low batteries in the controller.

Actually, I just checked that the voltage on all the batteries is 1.35V. So they appear to be ok, just charged much quicker than I would have expected.

Anyway,maybe I have an underlying issue instead? Frequencies here are different and it is possible that I might be getting interference with something else, but I have had this truck out before and not experienced this interference.

Any ideas?

Also for future charging, it appears there is a connection on the remote. It's labeled as 6V, 250mA. Are there wall chargers for this?

You should be able to pickup a charger that will connect to the remote. Just need to make sure the voltage, amperage, and polarity are correct.

Something like this should work.

I like that. Could have many uses! However, there may not be an overcharge protection built into the remote...

At that low of a current you should be fine leaving it on overnight or even a few days. Or just set the current even lower if that is possible.

How do you like that Exceed? I am looking at them...

Love it! I'm no expert and this is my first hobby-grade RC, but it's been a blast! I had to replace the steering servo, but that was a simple Plug-n-play operation after some help from the guys here.

This is what I have and the price has dropped, which makes it an even better buy:

hmmm, should I get a second??

I was looking at the 1/10 Mad Crawler they make.

They also make planes and a bunch of other stuff.

If you are looking to charge batteries remotely, you are going to want to build a reproduction of Tesla's Wardenclyffe Tower (http://en.wikipedia.org/wiki/Wardenclyffe_Tower). This tower was a critical component of Tesla's still-developing concept of Wireless power (http://en.wikipedia.org/wiki/Wireless_energy_transfer).

The tower design will need to scale to how far away the batteries are, as the power diminishes as per the inverse of the square of the distance. (http://en.wikipedia.org/wiki/Inverse-square_law) Depending on how remote your batteries are, the base of the tower alone could be as large as a single family home, and the attendant amplitude of the transmission power could require specialized FCC and/or ITU2 licensing.

Sounds like a fun project! Post pics!

Um yeah, sure. I'll get right on that. Do I have to grow out my hair so it'll stand up as I get closer to the tower as to gauge when I am close enough?

I like how you have already taken my idea and made it your own. I have a strong suspicion that this is going to work out really well for you.

Well, except for the growing my hair out part. It's pretty well thinned out on top, but it gets bushy around the perimeter pretty quickly. I guess that adds to the character!
