can someone point me in the direction of a good charger that will do it all ? I want to be able to charge/discharge my dnano and mini-z batts as well as lipo and others for larger scale cars.

check out the PN Charger. I have a couple and they are very nice.

+1 for PN charger. Not expensive at all, lots of options, and NO false-peaking either, it pumps the cells full of juice and you can feel it when you drive the car.

PN charger is the way to go. It does Nimh, NiCad and Lipo. I've had two for a while now and I haven't had any issues with them. I believe someone makes an adapter that allows you to charge dNano batteries from the PN and similar chargers as well. To my knowledge there is no charger that can do AAAs and dNano batteries without an adapter.

The PN charger is an excellent choice but you must carry around a 12V power supply as well. If you don't already have one it can add a significant amount to your start up cost. Especially if you get a real good one. Say like a Novak N-Power.

Thanks ,I don't have a dc power supply. What's a good one?

PN chargers also. A good power supply......MuchMore makes a couple good ones.

If you dont need a discharge function, the DTX Onyx is a good option. I have had very good results with it, and it is AC/DC so you dont need a seperate PSU. I forget which model number I have, could be the 220... but bang for the buck, it could be the best available.

The best charger I have used is the Graupner Ultra Duo Plus 40 (or if you have more money, the Plus 50), that's is the one I own.
The best thing that this chargers have, and other don't, is the possibility of equalize nimh chemical.
In the case of miniZ, this means you don't need a discharger/equalizer for nimh aaa batterys.
Using the balance port, you can equalize, balance and match a 4 aaa pack, viewing individual volts, internal resistance, etc ....
You can do breaking in motors, attach a wheel hotter, use the second port as a power supply, and it have 2 ports of charge/equalize.
King regards.

I have never heard of this charger... I am very interested in learning more about it :D

google it. It is a way cool rig. The 50 is even better. At that price point you should be able to live in it as well.

It has Reflex charging, I may need to get it for that reason alone :rolleyes:

hmm what is reflex charging?

also wondering if there's a pn charger or something similar that is ac/dc?
so that you don't need to lug around a 12v power supply...

Herman, I really dont know, but my comment was meant as a joke... to go with Reflex Racing ;)

lol... sometimes i can really be that dense...

went as far as googling it up.. and came up with this...

Abstract

In this paper, a reflex charging strategy with the energy recovery function for a bidirectional converter (BC) is proposed to build a novel reflex-based BC (RBC) for increasing the battery charging efficiency in an uninterruptible power supply (UPS). The proposed RBC can provide a reflex charging current profile to charge the battery to obtain a high battery charging efficiency and prolong the battery life cycle. Specially, negative pulse energy of the reflex charging current profile in the proposed RBC is recovered to reduce the battery charging dissipation. A 400 W prototype is design and implemented to verify the feasibility of the proposed RBC. Compared with a typical bidirectional converter, the battery charging efficiency and the battery charging speed are improved about 10% and 8.8% by the proposed RBC, respectively.


and it all sounded greek to me...

then found this...

NiMh and Reflex (Burp) Charging (http://www.rcgroups.com/forums/showthread.php?t=77231)

and it still sounds greek to me...

sorry to be off topic...

did some comparison between
PN Racing S6 NiMH/NiCd/LiPo/LiFe Multi Balance Charger (http://www.rckenon.com/public_html/shop2/catalog/product_info.php?products_id=4311)

and..

Thunder AC6 Smart Balance LiPo/Nimh Charger/Discharger w/ AC Adapter for 1-6 Lipo/ 1-15 Nimh w/ PC Analysis Software (http://www.nitroplanes.com/thac6smbalic.html)

looks like the only difference is that the thunder ac6 can take ac/dc...

anybody try this charger out?

Hahaha, there is a "REFLEX" charging mode for NiHm batteries!
See this article.

This is the top one with ac input and the more expensive ones!

Well, you need to do a balancing wire and connector and attach it to aaa battary charger stand (atomic, pn, etc.. the one you like).

I will try to post latter a photo of mine.

the PN Racing charger, Route 246 etc... all have the same functionality basically. The other chargers that ppl have suggested look like a good option.

These are not cumbersome by no means. Nice and small and put out more then enough for what your looking to do if you want to go the PN charger, Rte 246, etc route

The PN Charger is also available in the shop here (http://shop.tinyrc.com/product.php?productid=20187&cat=0&page=1). :) also carries Maha (http://shop.tinyrc.com/search.php?mode=search&page=1) however they are out of stock at teh moment.

Power supply cost next to nothing now. Any laptop power supply will put out 12-15V at 4-5 amps. That is probably very clean power too because is for a computer. That is enough to charge 4 packs at once. Most people already have several around the house from old laptops. They are cheap on ebay or garage sale or surplus store. Of course, if you do need one right now, you can't find one :)

For mini-z, there is no reason you need a 10 or 20A power supply unless you are going to charge batteries for your entire club. Forget about modifying a desktop power supply either. Not worth the trouble for mini-z. I once had a 40A one from a server. Way way overkill. Could probably fry every single battery I have in a minute.

246 Euros???
I agree, it could bring you a beer and make you a massage whille the batteries charges... :D

I have an accucel 6 (turnigy), and it does the job for a fair price (something like 25 bucks on hobbyking), but I'm considering a Maha charger for my AAA's!

ok, so i can buy the pn charger and pick up a laptop plug at goodwill to power it ? also, i think i could just remove the guts from the stock charger and solder on a deans plug and use it to hold the battery for charging right ?

Oh... just to say, I bought an Maha C9000 Charger this morning, a few minutes after I post. So, I'll give it a shot on it and see what this charger is capable of!

That is what I have been doing for about 2 years. Just turn the laptop power supply over and read what the output voltage is. PN charger need around 11-18V. That probably covers about 95% of laptop power supply. Just strip the wire from the laptop and solder to the charger cord. If you get the polarity wrong, the charger have reverse polarity protection. Try not to do it though.

Older charger like the DuraTrax Ice had a smaller input range of 11-15V. the charger didn't like being at the limit with a 15V power supply that was lying around. All newer chargers should have a larger input range though.
