Turnigy Smart6 80w 7A Balance Charger with Graph Screen
The Turnigy Smart6 will handle LiPo/LiFe up to 6S and NiMH/NiCd up to 17S with a charge rate up to 7amp. The Smart6 also offers unique functions usually found in much more expensive equipment. The LCD screen shows an amps/volts graph throughout the charge/discharge process giving you easy to read, realtime data. Also shown are individual cell voltage during charge with realtime updates throughout the charge cycle. There is also resistance display for checking the condition/performance of your packs, no more guesswork! Features; Charge/Discharge paremeters Graph Display Adjustable cut-off for charge/discharge functions Measures the internal resistance of your battery for perfromance checking Microprocessor controlled Delta-peak sensitivity (NiMH/NiCd) Individual cell balancing Li-ion, LiPo and LiFe capable Ni-Cd and NiMH capable 7A Max charge current Store function, allows safe storage current Time limit function Input voltage monitoring. (Protects car batteries at the field) Data storage (Store 10 packs in memory) Battery break in and cycling.
Spec. Input Voltage: 10~18v Circuit power: Max Charge: 80W / Max Discharge: 5W Charge Current Range: 0.1~7.0A Discharge current range: 0.1~1.5A Ni-MH/NiCd cells: 1~17 Li-ion/Poly cells: 1~6 Pb battery voltage: 2~20v Weight: 255g Dimensions: 135x80x25mm
This charger has built in JST-XH balance ports, which makes it compatible with Flightmax,Turnigy, Rhino and any pack with a JST-XH adapter.

Car Cigarette Lighter Adapter for Battery Chargers
Recently, I figured out that each battery cell voltage is slightly over 4.2V after charging.
As far as I know, the general rule of using LiPo battery is each battery cell voltage shouldn't be over 4.2V
So, I'm really wondering if this is OK or Not.
Any comment will be appreciated.
Thanks in advance.
This review is based on very quick test. I deliberately selected a worn 3s Lipo for this test knowing that the middle cell was beginning to give up and running lower than the two others. I had used a balancer but apparently the imbalance was too bad for it to fully deal with it and it could not charge the battery completely any more.
To my surprise, this charger noticed what was going on, dropped the charge current to 300mA and kept the other two cells at 4.20V while the middle one was charging up. It took a little while but it looks like the middle cell was charged up to almost full capacity as well. Probably this battery is close to the end of its life but this test proves that this charger does something right!
Being a skeptic person, I also followed the charging voltage with a Fluke 189 multimeter which has accuracy of ±0.025 when measuring DC voltage. The results were pretty good here as well: On the first three cells, the measurement differences were between 6mV and 15mV to the multimeter. In all cases the charger was underestimating the voltage which causes it to overcharge slightly but the error is very well within acceptable limit. I have not checked all the 6 channels (cells) since I had only 3s batteries to test with. There is a way to adjust the maximum charge voltage for each chemistry if you want to make sure that the cells are kept below recommended maximum. I

Turnigy Smart 6 The unit Work very good, have charge 2200/4000 mamp 3S Lipo and 4000 4s Lipos w/o a problem, balance is very good (check or QC with a good voltmeter) so no complaints, I like very much this little charger, the Graphs is OK to understand how the battery is performing but I wish they had provided a manual with some explanations to interpreted better the graphs, HobbyKing should MINIMUM supply a manual in PDF format so you can download that is why one less star. Pros: Good Quality, small foot print (easy to port to the field), accurate, user friendly (very intuitive menu), good quality Cons: Letters on the screen are a little small (in my opinion), it don’t come with a complete set of charging cables (basically it only come with XT60 charging connector no deans or etc.) so you better get the others if you need then, no manual, No banana plugs to connect to the Power Supply (it only come with alligator clip connectors), discharging is only 2 Amps will be better is it was around 4 or 5 amps.

i tested with 2200mah 3s lipo battery after full charge with smart6, cells are 4.20x4.20x4.20 full charged. easy menu, good cooling (not more noise), what i need i can see with one touch. and i plug "Temperature Sensor w/ Futaba plug (product id 11777)" to smart6 then i can read of battery temperature correctly. and the smart6 charger manual link is www.link stars product to this price. thank HK and turnigy
