Think of a large rack battery topping up the smaller 48V packs in an electric boat, vehicle, robot or off-grid setup.\u003c\/p\u003e\u003cp\u003eJoining two 48V banks directly is risky: if one is flat and the other full, the rush of current can trip a battery's BMS and nothing charges at all. The BB484830 limits the current to 30A and applies the correct charge voltages across a 39-60V DC range. It can be switched on by any 8-80V ignition signal, or by a selectable vibration-sense mode that wakes it when the vehicle is moving.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCurrent limited, so mismatched 48V banks can be connected safely\u003c\/li\u003e\n\u003cli\u003eCorrect charging voltages for lithium or lead acid 48V banks\u003c\/li\u003e\n\u003cli\u003eIgnition feed activation from any 8-80V signal\u003c\/li\u003e\n\u003cli\u003eSelectable vibration-sense mode\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput \/ output:\u003c\/strong\u003e 48V to 48V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating voltage range:\u003c\/strong\u003e 39-60V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharge current:\u003c\/strong\u003e 30A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e About 1600W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery types:\u003c\/strong\u003e Lithium or lead acid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition signal:\u003c\/strong\u003e 8-80V\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGenuine Sterling Power with Sterling Power's warranty.
