Please help me, when I turned on the charger everything seems ok but when I press hold the start button what I got is battery check displayed after that battery check low voltage, what to do? Called my dealer said he is inexperience with this. Please give me a simple steps, I have 2s 7.4v lipos one is mystery1250mah other is GE  POWER 1800mah

To power up the charger I am using 12v 3amp smps adapter

check if ur getting correct voltage from your adapter.. 3amp should do !

it might be possible you are using a higher voltage setting on the charger (3s, 4s etc)

ok thanx to both of u, will check the voltage, any advice or suggestion is welcome.

Great!B6 is gooood..
Yes, check what mode you selected in the B6.. even I used to have the same b6 charger.
P.S- How is the battery which you bought?   

to remove doubts use car battery instead..... this will narrow down the issue tracking

But take double precautions for battery polarity else say bye to charger in a split of a second.

b.6 is good charger but balancing is not proper, i think in new version of b6 the balancing is fine,

Hello Rahul battery still in Delhi am dying to use it, my elder sis is officially in Delhi now she'll bring it home, thanks . Just check the adapter, output is 12.2v, I am just a starter I can be wrong with the usage so pls anyone step by step fast charging mode and balance charging. Both batteries are 2s 7.4v 25c. Thanx to all for ur reply

Arey, Check the current of that adapter. atleast get 3-4Amp current adp (power supply)..
If you cant then plug the terminals onto your 12v car battery.( or any vehicle)

There is a possibility that the Lipo was over discharged. Do you have access to a multimeter or lipo voltage circuit to verify this? Even a new lipo that was not stored at the appropriate voltage can off itself over time.

Also, ensure that all connections are secure. The first time I plugged in my Lipo, the balance cable was slightly loose and I got a similar error.

Do you get the same error with other batteries?

Also, if your power supply is not capable of supplying the necessary wattage, you may get this error. Lower the charge current and try again.

If you need instruction manuals, a google search will give you several downloadable options. The manual for a clone will also work fine in most cases.

With both the lipos the same error. Can it be the converter pin that i use to connect on the input of the charger sometimes I have to turn it for my charger to power on. Using car battery dont wanna take risk coz I'm not experienced enough to do this. I removed the sticker of my adapter and the output is 12v 4.0A. My wife's TV repairman said today both the lipos have 3...something volts and the output from the adapter is 12.2 volts. Anyway to charge my 2s 7.4volts how to do.
Blue Screen appears
prog select, lipo batt
press enter
lipo charge 0.1A    7.4v(2s)
press hold enter key for 3 seconds
Is it correct, please tell and thanx

Think I find the cause, its that I used both my batteries until the there is no response so my guess is, both of them are under voltage. Like many people did is it safe to charge it in nimh or nicad mode as i have mentioned earlier both of them are 2s 7.4v one is 1250mah other is 1800mah . At what rate to charge them in nimh or nicad mode.

did ur problem solved............
