Radio - Servo - Gyro - Gov - Batt > New Futaba BLS servos NiCds only?

I was installing my new servos this weekend and I saw this on the back of the package.



Anyone know why Futaba would request NiCds only? I thought LIPOs could put out more current than NiCds anyways.

From what I flew today they do use a little more power than the standard S3152's but it did not seem like that much more.

I think the key item I'd take away from that picture is 6.0V max.

There was a time when NiMh packs couldn't cut the mustard when it came to high current demands due to a higher than usable internal resistance. The internal resistance of NiCd packs was relatively low compared to those NiMh packs, and that would be the reason Futaba puts that notice on the servos.

You can get decent quality NiMh packs these days that don't exhibit that problem, they would work fine.

As for LiPo packs, they can supply the current without a noticeable voltage drop, but you need to make sure you don't exceed that 6.0V rating to the servo.

Not to worry, it's basically legacy lingo on the packaging. People have been using them with NiMH, Lipo, Lion, A123, etc for many years now.

I figured it was not a big problem, I am running NICDs right now anyways, I just though it was a strange thing to put on a package.

Thanks for backing up my thinking.
