eBay item 192900450740

I have not bought anything from them yet but found them very responsive through Ebay. Contact name was Sophia

+1 Sophia was responsive but actually advised me to avoid this particular board (didn't say why) and pick up one of their other active balancers instead (the super capacitor or capacitor ones)

The active ones where the balance rate does not vary based on the voltage delta, are worth paying a lot more.

But this line in particular has got a great rep
