So i've been looking at these two chargers.

Thunder AC6
http://www.hobbypartz.com/thac6smbachw.html

Specification
Operating voltage: DC 11~18 volts
Charge/discharge power: max. 50/5 Watts
NiCd/MH: 1~15 cells
LiIo/LiPo/LiFe: 1~6 series
Pb: 2~20V
Charge current: 0.1 to 2.2A
Discharge current: 0.1 to 1.0A
No. of cycle: 1 to 5 times
Battery data memory: up to 5 data
Weight: 260g
Dimension: 140*95*28mm
Computer USB port
Temperature sensor port
Built in AC adapter

But for this, they say it charges up to 5 amps. but it specifies 2.2

Thunder AC680
http://www.hobbypartz.com/73p-ac680-accharger.html

Specs
Operating voltage: DC 11~18 volts
AC in: 100v-240v
50/60Hz
Charge/discharge power: Max. 80/10 Watts
NiCd/MH: 1~15 cells
LiIo/LiPo/LiFe: 1~6 series
Pb: 2~20V
Charge current: 0.1 to 6.0A
Discharge current: 0.1 to 2.0A
No. Of cycle: 1 to 5 times
Battery data memory: Up to 5 data

which one would you recommend purchasing? Or anything you guys suggest? Im not sure about Turnigy, but i heard its crap.

I can guarantee you the AC6 does, in fact, charge up to 5A rate. I owned one. Of course, it's only a 50W charger, so it's not going to charge 6s packs at 5A. In fact, it'll only charge 2s packs at 5A. Even 3s packs can only be charged at ~4.0-4.5A.

Both are decent, although limited charges. If you do not need AC input, I'd recommend something with more power as you will most certainly grow into it. 200W and a 10A charge rate really come in handy for either 6s packs and/or parallel charging multiple lower voltage packs. HK has the EC06-10 for a great price, but it's backordered.

If you don't mind spending a bit more for quality, however, its hard to beat an iCharger.

Tight! but yeah im looking for an AC/DC charger. I have a Trakpower 5600mAh 2s battery. I'll be also picking up a sky lipo of a 5000 mah 2s battery. i run a drift RC so then i was just thinking about going with the ac680. yeah? unless there is another charger that charges 2 batteries simultaneously.

Pretty much any charger will do multiple batteries simultaneously, either in parallel or in series, with the correct adaptors. Neither of the AC chargers are power houses, but you can do parallel or series charging with both. The difference between the AC6 and the AC680, as I understand, is 30W total power and a 6A vs. 5A charge rate. The AC680 will charge 4s packs at around 4.5-5.5A, so you could get a series adapter and charge two of your same capacity packs together as 4s. You would not want to charge a 5800mAh and a 5000mAh pack together is series, but you could do them in parallel.

I'm not familiar with other brands that accept AC input, so I can't help you there. Most chargers out there are DC only.

oh well. i'll just choose between the two. but im still debating between the ac6 and ac680. which one is most recommended. i'll end up getting the ac680 after what you have told me. but you charging them at parallel? dont charge them at the same time if they are at different mAh?

For parallel charging, they must be the same cell count but can be different capacity(mAh). For serial charging, they should be the same capacity but can be different cell count.

Hey Reeefo, if you don't mind me asking, which charger did you end up with? I had the Turnigy Accucell 6 and it was a good charger... for the smaller packs. Currently I don't go over 4s so I was considering getting the AC680. The accucell 6 still works, just can't read the display anymore after dropping my drill press vice on it. I've got to set it up REALLY carefully and remember the last setting so I can change it by feel (you might say).
