My best friday, with that really rare NIB Novak stuff !

[kenooze]

Yes we are in 2008, but When we know where searching ...

A New Novak NES-1A servo:


A New Novak Constant Current Charger:



And a most easy to find, New Digi Peak Plus Charger:

[a01butal]

Great find kenooze and just to illustrate what a small world it is I just got an NEC-1 at my lhs this morning, looks like it had been there a long time.
At first I thought it was an ESC. I wonder what the chances of 2 NEC-1 being found on the same day this many miles away.

Crazy, or funny ???

Yes the world are so small

and while searching ebay I happened on this:

I doubt it will sell with high initial bid but still it's the 3rd NEC-1 I've seen in 2 days, maybe there not that rare.

"It is fully functional, and still charges current batteries including LIpos"

[a01butal]

That's funny I didn't even see that, good one.

"It is fully functional, and still charges current batteries including LIpos"

Someone should notify that guy that charging a LiPo with that charger would yield VERY ugly results.




Why would someone say that about a charger that was made 20 years before LiPos were even used in R/C?

[Erich Reichert]

i can't wait to burn down my shop charging lipo's with it and collect on the insurance!!! I'll let you all know how it goes. LOL

[a01butal]

Erich, in a post on another thread I suggest that you might provide demonstrations at the Vintage Nationals on how to properly charge your LiPos during slow periods between races. In addition members in attendance will benefit greatly from your contribution and may even contribute to help defray hospital and rehab expenses.

I couldn't let it go, so I sent the guy a note about his very irresponsible listing and this was his response...

You are wrong.

I had a professional racer tech this unit of its capabilities. This spponsored engineer and driver who will remain nameless, specializes in electronic testing of components and has been involved in the testing, design, and inventions of rc electronic components for 20 plus years. If he says it can be done, then it can.


Whelp, then I guess I have no idea what I'm talking about. The fact that a charger was designed, produced and discontinued 10 years before a Lithium Polymer battery was invented and 20 years before it ever saw an R/C car has nothing to do with it. While you're at it, he should see if he can fire WWII bullets out of a Glock. Dumbass.






I'm sorry, but it's crap like this guy is pushing that allows everyone [who isn't informed] in the R/C racing world to freak out about the care and charging of LiPo batteries. The sky-is-falling mentality and fear of new technology stems from the fireshows regularly seen on YouTube that are intentionally caused by misuse like this. Just plain stupid. I almost want to buy this charger just so no one else does believing that it will still function on current batteries.

I guess technically he is correct. Any charger can charge any battery, the trick is really charge termination. Heck you could hook a lipo directly up to a 12v car battery and it would charge

It's a semantic thing, like the old saying it's not the fall that hurts but the sudden stop.
It's not the charge that blows up lipos it's not knowing when to stop charging
Still it's an iresponsible/ignorant listing

[a01butal]

Yes, technically correct you could charge a lipo but this particular charger has a temperature sensor or probe which you put on one of the batteries in the pack and it measures heat build up until at the right time it shuts off on its own. In a Nicd charger it charges all the cells at the same time but I was told because I don't have any Lipos or a charger that in the Lipo case they are charged individually so they each grow individually or get hot at different rates. How do you know which cell to set the temperature sensor on. At least that is the explanation I was given as I said I could be wrong but I'm sure we'll find out right here shortly.

[badhoopty]

my simple head thinks of nicads as buckets, nimh as a hose, and lipos as a syringe when it comes to charging them.

i dont see how you could use a charger designed to dump buckets in a battery thats meant to have a very specific amount of water injected in it or it will pretty much combust... especially with multiple cells in high voltage lipo packs...

forgive my analogy, but it works for me.

Actually.......................................................................all current calibers ammunition accepted by the current
Glock pistols were available during WWII, .357sig and .40s&w not withstanding, unless that was your point and
then..............................................good point.

[Eau Rouge]

Absolutely, the point is just because you can doesn't mean you should. Bad things can and probably will happen.




Old chargers weren't designed for a lot of things, and single cells that deliver 3.7v each is a lot different than cells that were of 1.2v. That's massive. 6- or 7-cells in a pack versus 2 in a LiPo. The charger probably wouldn't even recognize a pack connected to it.

With a LiPo, the charge cannot be terminated on a set voltage, either, which is how that charger will shut itself off. The capacity reached at 4.2 Volts per cell is only 40% to 70% of full capacity. You also cannot trickle charge LiPo chemistry because it cannot accept an overcharge without causing damage to the cell—and worse. We all know every one of those old chargers goes into trickle automatically.

I'm glad Erich got that thing, but I'd LOVE to know who his "professional expert" is who looked it over and decided that NiCd charger programming for 1983 was fine for today's batteries. Hell, that charger would screw up a pack of NiMh just as much as a pair of LiPo cells.



Moot point because one of us got it, but this kind of thing gets me as angry as watching the booger-eating goobers intentionally overcharging LiPos on YouTube videos (by hooking them up directly to a car battery) to show everyone how DANGEROUS they are. FUD is a favorite term of mine over the last 8 years or so, but you can also throw STUPIDITY into the Fear, Uncertainty and Doubt list, too.
