Hey I just got this 9.6v 1400mAh battery pack for my Kyosho Mini Inferno ST.

I was just wondering what charger I need to get to charge it.

I have a AC/DC Adapter for an airsoft gun with the same plug as the battery pack..
Can I use that one?
Here are the info on it.
Model: TY 18(35EC)
Input: AC220v.50Hz
Output: DC 7.2v 220mA

So I see that this adapter output 7.2v but can I still use that to charge the 9.6v pack?

If not can someone tell me what type of charger I need to get.
Someone showed me a charger they had in a web shop but I cant buy that one because it would not work with the Norwegian power grid.
I need to buy one from a Norwegian web shop so it works here but I don't know what to search for.
Do the type of charger that I need have a name?

Thanks.

There are a lot of choices, from cheap peak chargers to high end computerized chargers. My opinion: invest in a good charger which is able to charge nimh packs and the now popular LI-PO 's. This (http://cgi.ebay.nl/E-Station-501DX-Digital-Charger-Discharger-06BLH_W0QQitemZ160005257885QQihZ006QQcategoryZ5030 1QQrdZ1QQcmdZViewItem) is a good choice orthis (http://cgi.ebay.nl/New-Digital-Auto-NiCd-NiMh-Lipo-Battery-Charger_W0QQitemZ290005174124QQihZ019QQcategoryZ34 056QQrdZ1QQcmdZViewItem) . IT chargers a kind of batteries and it is not too expensive. Hope this has answered your question.

The problem is that I dont have much money right now.
Can I use a simple AC/DC adapter.
You know the ones that you get with all toys and stuff that have a battery pack in them.

Like the one in the picture that I got with an airsoft gun.
That one has the same plug as the battery pack.
But the batterypack is 9.6v and this adapter has Output: DC 7.2v 220mA.

Can I use it?

If not, can I use one with 9.6v output (if I can find one)?

I have been looking on some pages on the net about charging battery packs but none of the pages say anything about what voltage to use. So I guess you need to give the bettery the same voltage as it outputs or what?

Please help.
Thanks.

To be honest: NO! This is a trickle-charger for nimh/nicad. The batteries we use are developed for r/c applications like cars. Therefor they are made for fast-charging. The Intellect batts on the first page are made for charging at 2 amp or 2,5 amp charging zo you have the most voltage ( the more voltage the more revs your motor will spin) and the most milli-amps ( runtime) it will give. I use for my 1/10 car Intellect 4200mah and we charge them on 6amp. This will give me about 6 minutes runtime in my 1/10 touringcar (4wd) with 11 turn single motor (topspeed is 85-90km/u)

Ok thanks for helping me understand :)
I guess I have to wait til I get some more money then.
And use AA betterys for now.
I hate takeing them inn and out of the stupid battery holder.
Anyway.
I'll try and get one of the two you recommended.
I think I'll get the one with the lowest price.
Witch will not be wary low anymore after paying import duty (I think thats like US $15 - $25) and VAT (witch is 25% if the item price).

Thanks for the help.

Thanks for the help.I use this charger, it does ethier 8 cells (Nicd and Nimh) and 1-3 cell lipos. It is definitely worth the $90 in my book.

for $90 dollars, wouldnt a triton charger be better than that? 1-24 NICAD or NIMH and 1-4 LI PO/ION. those are better numbers.

I just got myself a Duratraxx Intellipeak Deluxe Charger.

I was thinking of charging the packs as slow as possible at 0.5A.

The Charger is also able to trick charge (0.1A).

What is the right thing to do charge a new pack ?

I got this from a note together with Xray's battery packs.

"Cycle the battery pack before using for the first time."

Set the charge current to 1/10th of the capacity.
-in your case, 140mAh

Charge for 14-16hours.(restart your charger if it peaks or set the trickle charge to be at 120mA

After the 14-16hours of charge, Let the pack "rest" for 1 day.

Then discharge the pack @ the capacity of the pack
-in your case, 1.4A
Set the cut off voltage to 0.9V. this equal 7.2V for you.

After discharging, Let the pack rest for 6 hours.

After all these, your pack is ready for use. You can charge @ 1.4Amp and use it in your car.

Hope this answers your questions and doubts.

Hey.
So winter came and I ended up never buying one last year.
I'm going to buy one now.

The old links in this post dont work anymore.

But I'm looking at this one:

http://cgi.ebay.com/New-Duratrax-Piranha-AC-DC-Digital-Peak-Charger-4005_W0QQitemZ160094251662QQihZ006QQcategoryZ44028 QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

http://www.duratrax.com/caraccys/dtxp4005.html

Its around half the price of the other ones that was linked to in this post.
So is this one any good?
It will work fine with my battery pack (picture in first post), right?

looks great. I opted for the deluxe peak and had constant problems. had to buy a good 13.8V powersupply. now works great.
