That smart bms comes programed, or you can buy them from a trusted european forum member set however you want. Not for the same price though, he has to program and test them, after paying just the same as us to get them. I reckon he would put some leads on though to make it plug n play if you asked. Bmsbattery send them set to your provided cell count and your chosen voltage thresholds. I have seen three from them, but they didn't actually get one right. I pay about $75 delivered from my european neighbour now.
