What a piece of ****. I just used the discharge function on two of my Turnigy nano-techs, hooked up through a parallel charger board, to see what their capacity was. At the end it showed that it had discharged the first cell down to 2.5 volts. Thanks a lot for f#*king my lipos hobbyking, you're the best!
Well I found another issue with Storage mode. On all of my other Turnigy chargers Storage mode does not care if the cells are below or above 3.8V/cell, they charge or discharge as necessary. With this charger if the cell is below 3.8V, the charger stops so the pack is below the correct storage value!! What a crock! I wonder how many batteries I have damaged because I put them away with one or more cells too low???
Another reason to recall this charger!
This charger definitely needs a calibration option. Balance charging does not complete properly. If the battety under balance is moved to another charger right away, the balance charge cycle on the 2nd charger completes in 30 seconds or less.
To think this is a Version 2 charger and the quality control plus Engineering departments missed such an essential feature. Quite a shame actually as this charger now is dangerous and could burn someones house down as in my case it is overcharging the batteries and can lead to a disaster.
One one think that Hobbyking woukd do the right vthing and either recall and fix the chargers, put out a 'stop use' warning and credit every customer who bought one or supply a new Version 3 with a calibration option.
This is vthe kind of event that will either distinguish them as an organization that is striving for quality and customer satisfaction or just another money grabbing swindler hiding in China.
Yes, if they request you to send back. The mail cost is by you.
Unless they accept your youtube video as proof. Then they normally will creadit back the charger cost only to your account to purchase again.
Most of the times, when I turn on the charger it stays frozen on "TURNIGY MEGA 400W" and buttons are not working. I have to reconnect it a lot of times to get it working again. Should I send this to HK service ?
For all of you: I tested this charger with 3 blue Turnigy lipos on a Hobbyking parallel board, each lipo being 6S/4Ah/40C. Combined with a good, stabilized 13.8Volt/40A PSU, which equals 550 Watts. That is plenty of current and power, but the voltage should not be high enough for this charger to reach the maximum power. 15 Volts is adviced. I programmed the charger to charge at 20 Amps, to make it run flat out. Knowing that it would never exceed 16 Amps, because that already equals 16A x 25V = 400 Watts. And with the low voltage, I expected it not to reach 16 Amps, that would be logical. More like 12-14 Amps or so.
To my surprise, it nicely went up to 16 Amps, and stayed there !
Conclusion: to reach 400 Watts with 6S lipos, you only need 13.8 (stabilised) Volts, which many common PSUs can produce. That was a nice surprise for me, thx HobbyKing.
As explained you then need 26,4A
3S is 11.1V
P=IxU (Power = Amps x Voltage)
As long as you powersupply is enough it works.
Then you are using just ONE balancer so be sure of some things:
- Same type of batteries is recommended
- Same charge
- ALWAYS check individual batteries after charging.
It appears to be a moot point. I am having no problems charging at 20A from a single 12v deep cycle marine battery at the field. With this charger I have stopped charging at the house.
I really like this charger.
I have the Turnigy 400w V2 charger together with a Hobbyking 540w power supply. When discharging a lipo battery I can't get any higher discharge than 1A. In the lipo discharge menu I can choose 5A as the discharge current, but when discharging begins it will not get any higher than 1A. This is on a 6s 2600mah lipo. Is there a setting somewhere in the menus that limits the current that I might have overlooked? Or is there something wrong with the charger?
Thanks for this reply! You are probably correct. So if I discharge a 3s battery I should be able to draw a little over 2A If my calculations are correct. The info on the charger should be changed to show discharge effect capacity in watts instead of amps... That would be a bit more explaining. Now it just says "1-5A discharge", it should say 25W discharge capacity to avoid confusion :)
Well I order one recently,and have my hopes up,I had Icharger for 3 months,and one of the mosfet blow up,and damage the tracks,they make the Icharger a very compact charger,never had a problem with the Icharger,but even if it was a faulty mosfet,will not buy again,because I was lucky it was inside warranty,finger crossed to see if they assume it,at least this charger if something burns is easier to fix it,the Icharger not really,a mosfet burned,and damage tracks.I advice you this charger for the price it is,of course the Icharger is superior,but I will never buy again,and I loved that charger,but well things happen,not risky again having one.
Wha do you mean by max rated and actual voltage? All my chargers charge up to the maximum actual voltage and capacity of the battery, which is 12.60V 2200mAh, for example. I think all the Lipo chargers "senses" the internal resistance and voltage of the battery and charge it based on this value. I just taking a guess here, correct me if Im wrong. Im new to this hobby :)
Can someone help me? In the charging menu, you can charge lipo or balance lipo. Where are the differences? The charging mode doesn't balance the cells?
I tried both today with 2200 3s Nanotech batteries. Can't see the difference at the end with a lipo cell checker, all cells are well balanced with both modes (0,05V max per cell)
In charging mode the voltage of the individual cells are only displayed but not balanced. In balance mode each cell is balanced. With a Lipo in good condition the cells should remain balanced. Charging mode is also faster than balance mode as time is not spent to balance the cells, only charge pack to 12.6 volts
You DO NOT cycle Lipo batteries. DO NOT cycle Lipo batteries, it is extremely dangerous to do this.
Lipo batteries do not need cycling like NiCad batteries.
If you want to store a Lipo for a long period (>3months) then the charger will have a function to discharge it slowly to about 30% charge rate.
10A/12V powersupply will work but will not reach its full potential. P=UxI or UxI=P U= voltage I=Amps P=Wattage so 12Vx 10A = 120Watt you can use the charger only just above a quarter of it's potential with a 10A powersupply.
well, you can charge up to 15-20 Amps, wich is probably more than the battery can handle. but a Turnigy nano-tech will handle it easily. You might also need a power supple that can supply enough amps for the charger!
Do u own this chrger sebastian??if i'm not mistaken we cannot chrge 20 amp with 6 cell btry!crrect me if wrong..let say if i chrge 6cell 5000 mah at 2c meaning at 10 amp,what will be the charging time?
I charge my 6S 5000 Lipo's with 6A max. The limit is by my 20A powersupplies, not the charger. P=UxI 400=22xI 6S=22V I=18A charge current at 22V But the power supply only delivers 13V so the power supply must deliver (22/12)x18A= 33A(12V) to use the chargers full potential
When I turn on I see USER SET **** Program
Every time I push battery type it changes to PROGRAM SELECT
Life - Nimh - Nicad - pb. I have tried leaving it on life and pushing other buttons but nothing gives me the choice of life/lipo/lilo.
I can't move it off Life.
I've got the same problem on my Venom charger, it's quite unusual but selecting between different type of Lithium is made in another menu, the one where you changing charging limits (mah, time, temp and so on). So the solution is: choose LiFe in one menu and then go to the other menu and select Lithium type between LiFe/LiPo/LiIon. That all!
Thank you for your reply.
I have already tried to find another menu that could do this but with out success. When I select Life there are only 3 other buttons I can push & none of them seem to take me to where I have the choices I need. Not having a manual is a curse.
I tried using 10amp 12volt PC power supplies with the smaller turnigy 10amp 200 watt charger however the Max volts registered by the charger from these was between 10 and 11 volts which meant I was only getting Max of 110watts to the charger which was OK with 3 cell batteries but hopeless with 6 cell ones as I was limited to a Max of 4 amps. I've just purchased a 540watt turnigy 30 watt power supply. This is putting out just under 18volts and has been the best purchase I've made so far. This sup
Very nice, Charging my 5000MAH 3cell at 15 amps no problem. Sounds like a jet engine. But me and my charger are both cool with that.

Solid design and the looks pre-calibrated as I compared the Charger cell voltages with my Lipo checker. They match perfectly. The charching per cell also seems to work fine as I tried this on a lipo with a unbalanced cell with a difference of 0.2V. My old Turnigy 150W charger with passive balancing could not quite handle these balancing differences. The active balancing of this charger can. Very helpfull on Zippy and Turnigy lipo's
Disadvantages: - Howling loud fan - No manual available - No calibration option found yet, but as it seems not required - The normal calibration sequence (Start and decrease durin power-up) shows a weird hidden menu which I do not understand.

I found the cause and solution to the howling fan which is REALY LOUD !! The cause is that in the construction they used to fans as a tunnel cooling. The slight difference in fanspeed creates the very anoying howling sound.
Solution: Disconnect the right fan by unplugging the right side small fan connector on the board. Tested this for a extensive period and the cooling is still very sufficient. But most of all: QUIET !!!!! Of course this is not a supported solution, be aware
Great charger, much like all of the Turnigy and Accucel versions. Would be better if there was a manual included, the fan noise was decreased by changing airflow design and if it ran off a maximum voltage of 24v DC.
