Hi, wondering if this board will function correctly if only 2 batteries were connected?
If not, do you carry a 2 battery version?
Thanks, Alex

Hi Alex,

Due to the fairly unconfigurable nature of this module, I’d say it wouldn’t be happy with just two batteries.

We don’t have a 2-battery version, but we do have larger LiPo pouch cells. What were you hoping to use this for?

Hi, I’ve connected this to three 18650 cells per the diagram but am getting zero voltage out.

Individually the batteries test good, and at the b+ and b- terminals it measures 12ish volts.

But nothing at the P+ / P- terminals?

Hi @Steven39383,

Welcome to the forums! Sorry to hear that you are having difficulties. There are a few things we need to best help out here. Can you:

  • Send through some images of your setup?
  • Check the voltage of your batteries and the voltage between B- and each of the other Bs?

If you can get this to us we are more than able to help out.

Hi Jack,

All good, I sorted it out. I just needed to connect it to a charger momentarily to wake up the BMS.

Thanks,
Steven P.

Hi Jack

I don’t think it would hurt to include this little gem somewhere in the product text.

A little trap for young players.

Well done Steven.
Cheers Bob

Thanks for that one Bob,

The description for this product should have a link to this forum thread and that handy tip added now!
