BMS 48V 30A suit LI-ION LIPO 48VOLT battery packs
HI QUALITY PROFESSIONAL BMS
YOU HAVE MOST LIKELY SPEND A LARGE AMOUNT OF CASH ON YOUR BATTERY CELLS SO WHY NOT PROTECT THEM WITH THIS PROFESSIONAL BMS FROM ONE OF THE LEADING PCB RESEARCH AND DEVELOPERS IN THIS FIELD
Function: Detect and protect the battery from over-charge, over-discharge, over-current short-circuit, temperature-detecting protection and automatic voltage balance function.
Built with high end electronic components (High End IC and MOSFET), simple structure design will let it have more stable quality working performance, flexible application (it can be used for less series battery by leaving some connection pins at empty status), full set of protection measures let it works well without any influence from external unexpected accidents.
