I would spend due diligence to find out where they are made and anything about quality. I'm highly suspicious that the are junk. Also beware of the warranty, though they do say "seller pays shipping". I once bought a product on Amazon from a US vendor but, when the product failed, he said I needed to send it back to China. (I ate the loss.)

 Is it possible to use individual chargers and no BMS on discharge? Is using spring loaded battery 
boxes feasible? We are taking about a 48 to 72 volt 10 to 20 ah battery. Is my design a recipe for 
failure or simplicity? Lawrence Rhodes
