Bantam BC6-10 to Parallel charge board.

[GIR8]

I have the above charger and just purchased a board from nexus not knowing the balance plug that goes into the charger would be different.
The Board also has 7 pins and the charger has 8 pins so looks like swapping the plastic plug end over isn't an option.

So folks what do I do? Obviously changing the balance board is cheaper than replacing the charger or is there a way to use the board with the charger?

[Rob Barnes]

I would change the board .

To what though? I was told this one would do but clearly doesn't.

The charger has 8 pins? If it's a 6S charger it should have a max of 7. I think we need some pics.

I've put 7 pin balance leads into an 8 pin port, but it needs to be lined up on pin 1 and obviously it's not recommended.

Hey buddy.

If it's the usual JST-XH balance connector you can get the housings, so could easily swap over the pins one by one once you know the first pin on the charger in the chain. Which is usually the negative pin to be honest.
Then with the right plastic housing orientation wouldn't be a problem in the future.

Ok so the top pick is the new balance/parallel charge board with 7 wires and below it is the plug from my old balance connector that fits the bc6-10

Hey Buddy.

Ah yea. Right, I think the one on the charger is called Hyperion/Polyquest and the one on the new board is the usual JST-XH standard found on most LiPo batteries. So it's looking like you need a Polyquest 8 pin to JST-XH, which you could make using the leads you have, but at the expense of cutting and soldering.

The charger appears to use the black wire as the first negative balance connection and then connects to each cell in series accordingly.

What would I do with the extra wire though considering there is 7 on the new board and 8 on the old one?
Soldering is not a problem I can do that as soon as I get my heatshrink I've ordered.
Thanks for all the help.

Hey buddy.

You're welcome.

Just leave the last wire out of the charger end, it's only to get the volrage of the 7th cell in the pack so isn't required to be there if unneeded.

The two black wires are tied into each other, wiring diagram here: https://commonsenserc.com/product_in...oducts_id=1367

So based on that diagram the way to do it would be pair up two black wires that come out of the Polyquest together and run as a single wire into the black wire position on the JST connector.

Just found that diagram a few mins ago. Thanks for all the help folks.

Quite funny I popped the back of the old Bantam balancer and that old black wire is soldered but not too any track or wire nothing. Why bother? just wasted 2 pins and a bit wire lol

Hey Buddy.

It was a good spot by Grumpy, but it did get me wondering why they would use two pins on the balance negative as the amperage won't be higher enough to warrant it. Seems they couldn't be bothered to wire it in after all.
