I am wondering what can be 'V2' about it too...considering the battery is the smart bit. Any info anyone? Is it shiny and new and better ... I'd hate to miss out if it is
The Battery Management System (Smart Battery) does the balancing internal to the Solo battery (just like the stock charger). You just tell the LiPo charger to "charge", not "Balance charge". In fact I'm just using the stock charger battery lead that I added an XT60 connector so I could swap it back and forth with the stock charger if needed.
These were made available on eBay last month. I don't see them now, but if the connector will work for you reach out to the seller to see if he has more.
I can't get any eBay links to work. The seller's eBay user ID is 13308256
