Very new to FPV & Quads...
I am building a couple micro quads to be the step up from some indoor FPV tiny whoops. In gearing up, I went with the SkyRC B6AC V2 charger for parallel charging 2s and eventually 3s/4s LiPos.
I picked up a couple balance boards and put the charger through some tests last night. I am thinking the 6S port on the charger is bad, but want to see if I might be missing something instead.
The charger will balance charge a 2S when the battery is connected directly to the 2S port on the charger's balance port. When I try to use either of the balance boards, I get a balance connect error. I have checked the balance board and the 6S cables that each uses to connect to the balance port on the charger. All the ports on both boards have good connectivity to the cable's 6S plug and the pins seem to be correct. Power also seems to be fine through out all the board's connections.
I don't have a 6S battery to test that connection on the balance port, so all I can imagine is that:
A. the charger will only allow 2S charging via the 2S socket in the charger's balance port, or
B. the charger has a faulty 6S port.
I really don't want to open up the charger to test the port, as it is literally fresh out of the box. Am I missing something that a typical boneheaded noob would overlook here?
Thanks. ![[-]](https://intofpv.com/images/collapse.png) • Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 Sounds like you're doing it right. I am not real sure how to check the 6S port on the charger.
Can you post some pics in case we are overlooking something else? I have an older B6AC but have not had this experience. • Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I had a balance board that was incorrectly soldered. And caused all kind of charging issue. I got a replacement from the vendor. They didn't want the defect board back, so I open it up and saw the incorrect soldering. I ended up fixing it.
I would contact the vendor.
If you want to fit it, you can take a photo of the board, and open up the back and take a photo of the traces. Maybe one of us can spot something.

The battery's balance lead voltages are perfectly readable from the plug. Pretty sure it's the charger's balance port connector. • Posts: 23 Threads: 5 Likes Received: 6 in 4 posts Likes Given: 4 Joined: Aug 2018 Reputation: 0 (10-Aug-2018, 10:22 PM)voodoo614 Wrote: I had a balance board that was incorrectly soldered.

I get the same results with both of them and I tested each pin on each connector to verify it's wired up correctly and not shorting anywhere. Looking on the inside of the board, nothing out of the ordinary. • Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 I actually have the same charger. Balance board works fine for me. Have you considered updating the firmware? • Posts: 2,410 Threads: 136 Likes Received: 1,790 in 1,052 posts Likes Given: 3,302 Joined: Jan 2017 Reputation: 50 Just a thought, but are you still setting it up for a 2S charge and not 6S right?
Firmware update could be worth a try as Voodoo suggested too.
Just some thoughts, hope you get it figured out man. • Posts: 5,324 Threads: 674 Likes Received: 3,161 in 1,748 posts Likes Given: 2,034 Joined: Jan 2016 Reputation: 139 check continuity of each pins in the balance port of the Parallel charging board. Make sure all the pins connects to the balance lead of the para-board.
Try a different slot see if you get the same error? I think the problem is more likely to be the board. • Posts: 3,533 Threads: 265 Likes Received: 2,610 in 1,545 posts Likes Given: 3,893 Joined: Feb 2018 Reputation: 78 You say you have checked the board several times. Have you checked the 7 wire connector from the charger to the board for continuity and cross shorting?

I have checked the board on all pins from the male 7-pin connector that plugs into the 6S female connector in the charger's balance port, to each pin on each connector on the balance board. Continuity is good to from every pin, and no shorting.
Basically, I am getting the results I would expect on all the balance board components. With a 2S battery on the board, I get the same reading at that connector as I get directly from the battery's balance lead. Also, no shorting on any other pin on the board. Either board, actually. Remember, I have two boards and both produce the same results.
I will try updating the charger's firmware and see if that does it.
Oh, and it is set to 2S on the charge program. • Posts: 155 Threads: 33 Likes Received: 17 in 15 posts Likes Given: 172 Joined: May 2018 Reputation: 2 • Posts: 23 Threads: 5 Likes Received: 6 in 4 posts Likes Given: 4 Joined: Aug 2018 Reputation: 0 (12-Aug-2018, 07:09 PM)Fisherking Wrote: your battery led is not connected. but I'm sure you are on to that. ??? • Posts: 3,533 Threads: 265 Likes Received: 2,610 in 1,545 posts Likes Given: 3,893 Joined: Feb 2018 Reputation: 78 Well, if it's not the battery, the board, or the board cable, then it has to be the charger. If firmware update doesn't fix it, take it back....frankly I doubt firmware update will fix it as it should do basic functions like you're trying to do with original firmware. Let us know what the fix is....

Let us know what the fix is.... Yep. I've checked everything. the boards and cables all check out. I know the charger works on the 2S balance port, so it really is down to the 6S balance port. Already had the latest firmware, so no change there. I'll update this once I get another charger... • Posts: 12,098 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 Here is a possible reason you get the error and how to fix it. https://www.rcgroups.com/forums/showthre...nect-error • |
