I have bought one from Linukas. If you guys think it will be better to get it from manufacturer, forget it. I have tried. It takes lots of time just explaining them what you want and in the end it costs more with TAX and shipping. 300USD is pretty cheap, you get sophisticated BMS, OK none of them will have all the functions each individual wants (unless u pay big bucks 1000+), but consider one sold here designed by ES members which is 250 + Shipping, TAX and still you have to assemble it your self and certainly will not b gettin fancy LCD
. I am not comparing those units just saying its convenient. The man is good with communications, and dispatch was swift, no problems what so ever. He was saying that he is testing BMS so in the end someone will be buying tested product.
I have not tested it and will be prob in summer as doing smaller project at the moment to familiarize myself with components and the way all fit together but will be posting experience with this unit later.
All the best
