Resolved by Nomad 6R!
My battery charger is not charging and the green light is always on? I have been able to charge a few times now without issue and this happened just yesterday. Cannot charge my robot now....
Is there anything I can check/do to get this working again?
@Richard, charge voltage is higher than 7.4v. The voltage across the outside 2 pins should be around 8.4v and it should be 4.2v between the first and second pins and 4.2v between the second and third pins.
Here's a good guide on everything Lithium Polymer
Blimey... It's a Christmas miracle, it is... Nomad just received a store credit...
Oh, man I am going to get crap for this one....
Good on ya' @nomad....
Cheers...
@Rich, I was just explaining the normal voltage of a 2S lipo battery itself... Yes, I do know the charger will charge a 2S battery to around 8.4v when fully charged...

i got two wright this time.
thats two brain cells activated hehe
thanks
@nomad... awesome.... Doing great... and good eyes by the way...
Well, you didn't exactly get it right, you gave a solution...
Tto be honest, buy a new balance charger isn't an ideal solution and it's not actually been determined that the charger isn't charging. It could be a coincidence that the green light is always on but if the battery is under volt it wont charge, this would be a battery problem and a charger problem.
We don't know the voltage of the battery at the moment, we don't know the output voltage of the balance charger either.
The green light remains lit on one of my balance chargers despite it being fully charged and balanced. On occasion it has turned off but it does remain on too. It's not one of my ones from EZ-Robot but it is the exact same design, just rebadged as something else.
Another user may see this topic and instantly think the balance charger is faulty when it may not be.

well i disagree, using a faulty charger can ruine your batt too. the learn section tells you how the charger works,red&green led. and averyone is asumed to read the hole topic.
We haven't determined that the charger is not charging though, all we know is the green LED remains on all the time.
We also haven't determined if the battery itself has become damaged. A new balance charger for a battery that has been damaged due to under voltage (possibly through the use of a faulty charger) will not solve the issue either.
The whole topic doesn't give this information. Diagnostics is incomplete.
