hi guys and girls i have a question for any one that know whats wrong. ok i just bought a venom lipo 3400 mah battery and i have a onyx 2300 lipo charger and i have a equinox lipo cell balancer now i hooked it all up and set up the charger and the balancer will not light up at all and when i push start on the battery charger it says no battery and the battery is new i got today and the charger and balancer is new but it is about a year old but this is the fist time i used it.

sounds like a dead battery or bad connection test the battery output leads with a voltmeter.

dude he can have his hair any way he wants and can pay as much he want for a charger dude he posted this vid to help people not for people to judge him

[on2you]

what are you the hair police or something? This dude is helping people and saving them money. Why be negitave and make a comment to that regard. He is not showing you a video on a barber shop, if you were after that this video is not for you. Congratulations on the Captain An@! award for the week.

p.s. cool vid wish i had looked at it before i stuffed my lipo.

hi

it happened after 2 cycles,i wont be sending it back to hobbyking, id rather nurse it better or reduce the pack to 4s.

[BigMat478]

@1521joe

Yeah that can happen with cheaper lipos. It will still work fine but will give you less charge time on the battery. Was it like that from the beginning? or it happened after using it for several times?

@BigMat478

hi

thank you for the info.

may i ask 1 more question.

in a 4 cell battery, what would you do if you noticed a weak cell or a cell that wasnt as good as the others.

for example... after finishing a balance charge, all cells are at 4.2v except 1 of those cells is at 4.1, while balance charging, you notice that cell falling behind so when all other cells are at 3.9v, this 1 cell is at 3.6v.

some of the far east lipos are particularly prone to doing this.

sincere thanks

@1521joe coz if u fully charge the battery and you don't use it for quite some time it may get damaged. Lipo batteries are very good but delicate. You must take good care of them in order to serve you for a long time

@wheelyking23

did you plug in the main red and black wires?

1 year on...you should have solved it by now

right?

[1521joe]

@energyrc

no.

every charger im aware of will need the main blk/red wired plugged in also.

A balancer like the hobbyking medic doctor will charge your battery through the balance port, thats only because its desighned to balance out of sync cells, and it should be noted takes several hours to do so.

hope this info helps
