The BMS and Charger came the other day way earlier than promised. Both 
packages came from an address no more than 10 miles from my house....maybe 
there are stockpiles in the US? But why would they say from China using speed 
pack.  Any way no instructions came with the package. The BMS looks 
professionally manufactured. Has a 5 and 20 pin connector. It is the size of a 
small smart phone and very heavy. I have no idea how to hook up the negative. 
The diagram(on ebay) assumes a lot of knowledge I don't have.  I am not even 
sure I can safely start this project.
 If this is a common BMS with maybe a video somewhere that might help me. Maybe 
someone here has used this model.  About all I know is the 20 pins go on each 
parallel connection of which there will be 20. The P will be two. Plenty for a 
small battery for a bicycle. But documentation in the form of diagrams is 
lacking.  But for the money if I can figure it out not bad.  Lawrence Rhodes
