I've never dealt with BestGo, but here's a thread on DIYelectriccar:


I think when it comes to battery importers, IMHO,  it's best go with 
reputable tried & true since there are so many fly-by-night operations 
out there...
BTW, I know you are looking for large prismatics, but for anyone 
interested, I have a couple hundred Headway 10AH screw-terminal 
cylindrical cells I am looking to sell.  $12/ea.  They are currently 
assembled into 4S8P T-shaped packs.  They are a couple years old, but I 
take meticulous care of them, and they are pretty much unused.  All the 
cells have been tested to keep their charge (had about a half dozen that 
were duds) but I haven't tested them for discharge current capabilties.  
I charge them up about once every 3-4 months, so they are in excellent 
condition.  For a small additional charge, I can probably arrange them 
in pack configurations (with nickel plated copper bus plates) for you 
(assuming I have enough holders and plates).
