Default Lipo Balancing question.

I have a Orion 3s Carbon edition lipo for my scaler and have a question about balancing for it. I finally found a balancing adapter for my hyperion that works for it (its made by pro-teck). Now my question is, on the lipo battery, there is 2 balancing ports. A port A and a port B. There is the two balancing wires that come off the adapter (a red and a black) port B is on the posative side of the battery while the A is on the negative side.. I plugged the red balancing wire in port B and the black on port A. With this setup it should charge and balance at the same time. But while I do this, it never seems to end. I let it charge/balance for over 3 hours and it still was going. Its a 3500mah lipo, so I know it shouldnt take that long.. Am I doing something wrong? Any help would be appriciated. I can take pictures if needed.

What are your charger settings?

Thats a 3S hard case so it uses a special harness (for 3S, has an extra bullet coinnector) you mentioned from Protec. I'm guessing, but are you sure the 2 wires that plug into the lipo case are correct polarity wise? Otherwise, your symptoms sound like cells are just way out of balance cause thats typically what makes balancer work for a long time. This would be the 1st Orion that I've heard of with the cell voltages that far off. Makes me think the wiring is not correct.

Do you see all 3 cell voltages on the charger panel? When correctly connected, you'll be able to read the voltage on each cell. I guess the other potential issue is that there's something work inside the lipo with the balance wiring - usually a small circuit board that all this is wired to. Something could be wrong there, bad solder joint is usually prob if there is one.

If you connect the harness to your lipo, you should be able to read the 3 cell voltages off the plug that goes to the charger. Have you tried checking it that way with a dvm to see what the voltage spread is between the 3 cells??

I'd be curious to see a picture of your balance lead. This may be a dumb question on my part but, you mentioned you had the two wires connected to the balance ports (A/B) but you didn't say anything about having connected the other 2 wires to the main power (+-) leads/ports. Are you aware that you need to have all 4 wires connected?

Your balance lead should look something like this



Except for the fact that it would have an extra wire right next to that skinny black one. One end of the middle wires go to A/B balance port on the pack and the other end goes to the balance plug that connects to your charger. The layout/order of all 4 wires is the same on the plug as it is on the batt. So...neg-A-B-pos on the batt, and they'd follow that same layout in the plug that connects to the charger.

The lead in the pic is for a 2 cell and the balance plug and leads on the left go to the charger's balance port and +- charge connections. The leads on the right go to the main +- ports on the batt, and the skinny black one goes to the balance port in between them, as a 2 cell only has one "balance port". All the wires on the right have to be connected to the batt. Only the balance connector on the left has to be connected for "balance only" mode w/out charging. The main leads can be connected w/out the balance plug being connected if you want to use "charge only" mode w/out balancing.

Some people that opt to have their main leads soldered to the pack and use a (female) Deans (or whatever) connector on the pack, replace those main +- bullet connectors on the adaptor/balance lead with a (male) Deans (or whatever) but they still have to be plugged in.

Sorry bout the wordiness.

He has this adapter - note the 2 smaller bullets for his 3S hard case lipo which has 2 balance ports in the lipo versus a single balance port found on a 2S. Has a total of 4 wires, 2 each black and red.

Yeah, that's exactly what I described. I just didn't have a pic of a 3s adapter handy. So the question remains...is the OP aware that all 4 wires have to be connected to the batt? For the adapter in the A Main link, it doesn't matter if the larger bullets or the Deans connector goes to the batt's main leads but they do need to be connected along with the smaller bullets to the A/B ports. As far as which of the smaller bullets goes to which port, the wires lay out the same on the batt as they do on the white connector. In other words, you could label the wires in the white connector as Black-A-B-Red in that order. So looking at the connector, the wire next to the black wire connects to port A on the batt the wire next to the red wire connects to port B on the batt. I apologize if I'm pointing out the obvious here.
