Their website hasn't had any updates about their new Pathfinder BMS since Sept. ??? I would support a product designed in the USA, with good documentation and software support.

I recently saw the price of the SOK SK48V100-NCBT drop to $1,099. which I thought was an incredible bargain, considering Will liked it at $1,300.
However, on Current Connected's website it now says, "*NOTICE* Discontinued by the Manufacturer" and they are "Out of stock until May ~ June"...
