Xima Lhotz Posted February 8, 2017 Share Posted February 8, 2017 Hi. I was in the process of rebuilding my 340wh Lhotz, adding a standard 180wh battery with its own BMS to have 520wh total. I accidentally shorted the charge wires with catastrophic result. Batterypack started to smoke, the plastic melted and the charge wires started to melt. Luckily the chargewires didnt melt completely before I managed to separate the short, if i hadn't I'm sure a batteryfire was imminent. So now to my question, doesn't all BMS have short protection on the charge wires? To me it's mental not to have. It's just as dangerous as not having it on the output wires. How is it that I could draw this high current from the charge wire anyhow? feels like a faulty design. Is this standard manufacturing practice or is this BMS a really bad one? Batterypack in question. https://m.aliexpress.com/s/item/32686348373.html?trace=wwwdetail2mobilesitedetail&productId=32686348373&productSubject=32686348373&shortkey=VJ77Vfia&addresstype=600 Link to comment Share on other sites More sharing options...
